Description

Technical Field

[0001] The present disclosure relates to the field of logging technologies, and particularly to an optical fiber positioning method and apparatus, an electronic device, and a storage medium. Background Art

[0002] Optical fiber logging is a newly emerging logging technology that has developed rapidly in recent years. In particular, distributed optical fiber logging has attracted much attention due to its advantages such as large amounts of data, high resolution, and a large number of measurable items. Among them, the permanent optical fiber logging project outside the casing, as one of the most accurate and promising technologies in optical fiber logging, has broad application prospects in the field of oil and gas exploration and development.

[0003] However, since optical fiber logging is a newly emerging logging technology, the supporting related technologies and methods have not kept up in a timely manner, and many contradictions have emerged in the actual production process. Among them, the problem of avoiding radiation of the optical fiber outside the pipe (casing) is particularly prominent. If the avoidance of radiation fails, it will directly lead to the failure of the construction, resulting in huge losses. Currently, the main test method for avoiding radiation of the optical fiber outside the pipe is the MOT technology. However, this technology was not developed specifically for avoiding radiation of the optical fiber outside the pipe, but is a technology borrowed from detecting the magnetic signal of the casing collar in drilling. Unfortunately, this technology has great uncertainty because it infers the position of the optical fiber outside the pipe by measuring the magnetic signal of the optical fiber clamp at the casing collar.

[0004] In current production practices, the situation of failure in avoiding radiation of the optical fiber outside the pipe is relatively common. To solve the problem of positioning the optical fiber outside the pipe, the present invention proposes a thermal imaging method. This method is specifically proposed for the deficiencies of the current technology for positioning the optical fiber outside the pipe, is targeted, and is also a dedicated supporting technology in the field of optical fiber logging.

[0005] With the continuous development of optical fiber logging technologies, technologies that can effectively solve the problem of positioning the optical fiber outside the pipe will be widely applied. At the same time, with the continuous improvement of related supporting technologies and methods, optical fiber logging technologies will have a broader application prospect. We have reason to believe that through continuous innovation and technological progress, optical fiber logging will play an increasingly important role in the field of oil and gas exploration and development and make positive contributions to the development of the industry.

[0029] The problem of optical fiber positioning outside the pipe is a major challenge in optical fiber logging. In traditional methods, due to interference from various factors, such as temperature changes and optical fiber losses, the positioning results of the optical fiber outside the pipe are inaccurate. This inaccuracy seriously affects the accuracy and reliability of logging data.

[0030] During the process of external permanent optical fiber logging, a key issue is how to accurately determine the azimuth of the optical fiber outside the pipe in the perforation section (reservoir). When using traditional methods for logging, there are often troubles with inaccurate positioning of the optical fiber outside the pipe. The present disclosure will introduce a new technical solution, which improves the success rate of optical fiber logging by solving the problem of optical fiber positioning outside the pipe.

[0031] Figure 1 A flowchart showing a fiber optic positioning method according to an embodiment of the present disclosure. Figure 5 It is a schematic diagram of the actual application corresponding to a logging instrument or a fiber optic positioning method shown according to an exemplary embodiment. As Figure 1 well as 5 shown, the fiber optic positioning method includes: Step S101: Control the heating element 3 configured at the set target formation position 9 corresponding to the fiber optic 1 outside the casing 6 to generate heat; Step S102: Use the detection mechanism 5 inside the casing 6 to detect the temperature value of the heating element 3; Step S103: Based on the temperature value and the set temperature value, determine the azimuth information of the fiber optic 1 at the set target formation position. To solve the deficiency of inferring the position of the fiber optic outside the pipe by measuring the magnetic signal of the fiber optic clamp at the casing collar. Among them, those skilled in the art can configure the set temperature value according to actual needs. For example, the set temperature value can be configured as 90°C, 120°C or other values.

[0032] In the embodiments of the present disclosure and other possible embodiments, the casing 6 is arranged in the formation 8, and multiple set target formation positions 9 are arranged at different depths in the formation 8. According to the actual needs of logging, it is necessary to perforate the multiple set target formation positions 9 arranged at different depths in the formation 8. Before perforation, it is necessary to determine the azimuth information of the fiber optic 1 at the set target formation position to avoid perforating the fiber optic 1 at the set target formation position 9 during perforation, causing the fiber optic 1 to break.

[0033] For example, in the embodiments of the present disclosure and other possible embodiments, the fiber optic 1 azimuth information includes: the depth information and the horizontal azimuth information corresponding to the set target formation; among them, since the fiber optic 1 is at the set target formation (perforation horizon), the depth information of the fiber optic 1 azimuth information has been determined, and only the horizontal azimuth information in the fiber optic 1 azimuth information needs to be determined.

[0034] Step S101: Control the heating element 3 configured at the set target formation position 9 corresponding to the fiber optic 1 outside the casing 6 to generate heat.

[0035] In the embodiment of the present disclosure, the method for controlling the heating element 3 configured at the set target formation position 9 corresponding to the fiber optic 1 outside the casing 6 to generate heat includes: controlling the detection mechanism 5 to fall in the casing 6 to the set depth corresponding to the set target formation position at the initially set first set speed; at the set depth, controlling the detection mechanism 5 to send a heating control signal to the heating element 3; after the heating element 3 receives the heating control signal, the heating element 3 generates heat.

[0036] In the embodiments of the present disclosure and other possible embodiments, the number of the set target formations (perforation horizons) is at least one, that is to say, the number of the set target formations (perforation horizons) can be multiple; correspondingly, the number of the heating elements 3 is the same as the number of the set target formations (perforation horizons), and a corresponding heating element 3 is arranged in each set target formation (perforation horizon).

[0037] In the embodiments of the present disclosure and other possible embodiments, for the target area that needs to be monitored or located (the set target formation or perforation horizon), appropriate optical fibers 1 and heating elements 3 are selected to ensure that the installation positions of the optical fibers 1 and the heating elements 3 are adapted to the target area. Specifically, the formation height corresponding to the set target formation is obtained; based on the formation height corresponding to the set target formation, the element height of the heating element 3 is determined; wherein, the element height is at least greater than or equal to the formation height.

[0038] Therefore, in the embodiments of the present disclosure and other possible embodiments, before the heating element 3 arranged at the set target formation position 9 corresponding to the optical fiber 1 outside the control casing 6 generates heat, it is necessary to determine the set target formation position 9, and then control the heating element 3 arranged at the set target formation position 9 corresponding to the optical fiber 1 outside the control casing 6 to generate heat.

[0039] More specifically, the optical fiber 1 outside the casing 6 and the heating element 3 arranged at the set target formation position 9 corresponding to the optical fiber 1 have been fixed in the formation 8. The optical fiber 1 is fixed outside the casing 6, and the corresponding heating element 3 is fixed on the outer side of the optical fiber 1 or at a set distance from the outer side of the optical fiber 1. Therefore, the optical fiber 1 is also called a permanent optical fiber. Among them, those skilled in the art can configure the set distance according to actual needs. Specifically, the heating element 3 is arranged on the surface or near-field position (the set distance) of the target area (the set target formation position 9) of the permanent optical fiber (optical fiber 1) outside the casing to ensure that the arrangement mode of the heating element 3 can cover the target area and obtain a high thermal imaging resolution (the heating element 3 is close to the casing).

[0040] In the embodiments of the present disclosure and other possible embodiments, a method for configuring a heating element 3 disposed at a set target formation position 9 corresponding to an optical fiber 1 outside a casing 6 includes: obtaining a plurality of set distances to be determined; respectively disposing the heating element 3 outside the optical fiber 1 based on the plurality of set distances to be determined; respectively controlling the heating element 3 to generate heat at the plurality of set distances to be determined; using a detection mechanism 5 for simulating inside the casing in a laboratory to detect a plurality of temperature values of the heating element 3 at the plurality of set distances to be determined; and respectively performing thermal imaging on the plurality of temperature values detected by the detection mechanism 5 at the plurality of set distances to be determined to obtain corresponding thermal imaging diagrams; determining the set distance between the heating element 3 and the outside of the optical fiber 1 from the plurality of set distances to be determined based on the resolution of the plurality of thermal imaging diagrams and a preset resolution. Wherein, those skilled in the art can configure the plurality of set distances to be determined according to actual needs.

[0041] Those skilled in the art can configure the heating element 3 according to actual needs. For example, the heating element 3 can be configured as a resistance wire or other heat-generating devices.

[0042] In the embodiments of the present disclosure, after the heating element 3 generates heat, the detection mechanism 5 is controlled to move along a first vertical direction and a second vertical direction opposite to the first vertical direction inside the casing 6 at a second speed less than the first set speed initially set; during the movement along the first vertical direction and / or the second vertical direction opposite to the first vertical direction, a plurality of temperature values of the heating element 3 at different formation depths are detected; and the azimuth information of the optical fiber 1 at the set target formation position is determined based on the plurality of temperature values of the heating element 3 at different formation depths and the set temperature value.

[0043] In embodiments of the present disclosure and other possible embodiments, before controlling the detection mechanism 5 to move in the casing 6 along a first vertical direction and a second vertical direction opposite to the first vertical direction at a second speed less than the first set speed set initially, obtain a first height corresponding to the detection mechanism 5 and a second height corresponding to the heating element 3; if the first height is greater than or equal to the second height, control the detection mechanism 5 to move in the casing 6 along the first vertical direction and the second vertical direction opposite to the first vertical direction at a second speed less than the first set speed set initially; during the movement, when the first magnetic positioning mechanism arranged at the center position of the detection mechanism 5 moves the second positioning mechanism arranged at the center position of the heating element 3, control the detection mechanism 5 to stop moving in the casing 6 along the first vertical direction and the second vertical direction opposite to the first vertical direction. Meanwhile, if the first height is less than the second height, control the detection mechanism 5 to move in the casing 6 along the first vertical direction at a second speed less than the first set speed set initially; during the movement along the first vertical direction, when the first magnetic positioning mechanism arranged at the center position of the detection mechanism 5 moves the third positioning mechanism arranged at one end of the heating element 3, control the detection mechanism 5 to stop moving in the casing 6 along the first vertical direction, and control the detection mechanism 5 to move in the second vertical direction opposite to the first vertical direction; during the movement along the second vertical direction, when the first magnetic positioning mechanism arranged at the center position of the detection mechanism 5 moves the fourth positioning mechanism arranged at the other end of the heating element 3, control the detection mechanism 5 to stop moving in the casing 6 along the second vertical direction.

[0044] In an embodiment of the present disclosure, the method for controlling the detection mechanism 5 to fall in the casing 6 to a set depth corresponding to a set target formation position at a first set speed set initially includes: controlling the detection mechanism 5 to fall in the casing 6 at the first set speed set initially, and obtaining a real-time depth at which the detection mechanism 5 falls in the casing 6; calculating a deviation between the real-time depth and the set depth in real time, and adjusting a speed corresponding to the real-time depth based on the deviation, and using the adjusted speed to control the detection mechanism 5 to fall in the casing 6 until the real-time depth is equal to the set depth or the deviation between the real-time depth and the set depth is within a set depth deviation range.

[0045] In embodiments of the present disclosure and other possible embodiments, the detection mechanism 5 can be controlled to fall in the casing 6 based on a proportional integral derivative control algorithm until the real-time depth is equal to the set depth or the deviation between the real-time depth and the set depth is within a set depth deviation range.

[0046] In an embodiment of the present disclosure, the method for determining the azimuth information of the optical fiber 1 at the set target formation position based on multiple temperature values of the heating element 3 at different underlying depths and the set temperature value includes: calculating multiple differences between adjacent multiple temperature values at different underlying depths and the set temperature value respectively; determining the optical fiber depth information along the casing 6 and the plane position information perpendicular to the plane corresponding to the optical fiber depth information in the azimuth information of the optical fiber 1 at the set target formation position based on the multiple differences and a preset difference. Obviously, in the embodiments of the present disclosure and other possible embodiments, those skilled in the art can configure the preset difference according to actual needs.

[0047] In an embodiment of the present disclosure and other possible embodiments, the method for determining the optical fiber depth information along the casing 6 and the plane position information perpendicular to the plane corresponding to the optical fiber depth information in the azimuth information of the optical fiber 1 at the set target formation position based on the multiple differences and a preset difference includes: if the multiple differences are less than the preset difference, determining the optical fiber depth information along the casing 6 and the plane position information perpendicular to the plane corresponding to the optical fiber depth information in the azimuth information of the optical fiber 1 at the set target formation position; if the multiple differences are greater than the preset difference, determining the starting point position information and the end point information (i.e., the optical fiber depth information) corresponding to the optical fiber depth information along the casing 6 in the azimuth information of the optical fiber 1 at the set target formation position.

[0048] Step S102: Use the detection mechanism 5 in the casing 6 to detect the temperature value of the heating element 3.

[0049] In an embodiment of the present disclosure and other possible embodiments, the detection mechanism 5 in the casing 6 can detect the temperature values of all horizontal azimuths within a set circumferential range at the set target formation. Among them, those skilled in the art can configure the detection mechanism 5 according to actual needs, for example, configuring the detection mechanism 5 as a thermal imager 5.

[0050] In addition, in an embodiment of the present disclosure and other possible embodiments, after the heating element 3 starts heating, control the detection mechanism 5 to move in the casing 6 along a first vertical direction and a second vertical direction opposite to the first vertical direction at a second speed less than the first set speed initially set; during the movement along the first vertical direction and / or the second vertical direction opposite to the first vertical direction, the detection mechanism 5 in the casing 6 continuously detects multiple temperature values of the heating element 3 at different underlying depths of all horizontal azimuths within the set circumferential range.

[0051] In the embodiments of the present disclosure and other possible embodiments, during the process of calculating the deviation between the real-time depth and the set depth in real time, adjusting the speed corresponding to the real-time depth based on the deviation, and using the adjusted speed to control the detection mechanism 5 to drop in the casing 6, the detection mechanism 5 in the casing 6 detects the temperature values of the heating elements 3 at different underlying depths in all horizontal orientations within a circumferentially set range in real time.

[0052] In the embodiments of the present disclosure, the method of using the detection mechanism 5 in the casing 6 to detect the temperature value of the heating element 3 includes: obtaining the starting moment when the heating element 3 starts to generate heat; after the set time period has elapsed after the starting moment, using the detection mechanism 5 in the casing 6 to detect the temperature value of the heating element 3. Among them, those skilled in the art can configure the set time period according to actual needs. For example, the set time period can be configured as 5 seconds, 10 seconds or other values.

[0053] Step S103: Determine the azimuth information of the optical fiber 1 at the set target formation position based on the temperature value and the set temperature value.

[0054] In the embodiments of the present disclosure and other possible embodiments, the method of determining the azimuth information of the optical fiber 1 at the set target formation position based on the temperature value and the set temperature value includes: if the temperature value is greater than or equal to the set temperature value, configuring the azimuth information of the heating element 3 as the azimuth information of the optical fiber 1 at the set target formation position; otherwise, the optical fiber 1 does not exist in the azimuth where the temperature value is located.

[0055] Furthermore, since the optical fiber 1 outside the casing 6 and the heating element 3 configured at the set target formation position 9 corresponding to the optical fiber 1 have been fixed in the formation 8, the optical fiber 1 is fixed outside the casing 6, and the corresponding heating element 3 is fixed at a set distance outside the optical fiber 1 or on the side fixed to the outside of the optical fiber 1. Therefore, the azimuth information of the heating element at the set target formation can be determined by using the temperature value of the heating element 3 and the set temperature value, and then the azimuth information of the optical fiber 1 is determined.

[0056] In the embodiments of the present disclosure and other possible embodiments, the method of configuring the orientation information of the heating element 3 as the orientation information of the optical fiber 1 at the set target formation position includes: if the heating element 3 is attached to the outside of the optical fiber 1, directly configuring the orientation information of the heating element 3 as the orientation information of the optical fiber 1 at the set target formation position; wherein, the orientation information of the heating element 3 includes: the preset depth information of the heating element and the preset horizontal information of the heating element; if the heating element 3 is arranged on the fixed side outside the optical fiber 1 at a set distance, the horizontal position information obtained by adding / subtracting the set distance to / from the preset horizontal information of the heating element and the corresponding preset depth information of the heating element are configured as the orientation information of the optical fiber 1 at the set target formation position.

[0087] In the embodiments of the present disclosure and other possible embodiments, after the heating element 3 generates heat, the cable 4 connected to the detection mechanism 5 is used to control the detection mechanism 5 to move in the sleeve 6 along a first vertical direction and a second vertical direction opposite to the first vertical direction at a second speed less than the first set speed initially set; during the movement along the first vertical direction and / or the second vertical direction opposite to the first vertical direction, a plurality of temperature values of the heating element 3 at different underlying depths are detected; based on the plurality of temperature values of the heating element 3 at different underlying depths and the set temperature value, the azimuth information of the optical fiber 1 at the set target formation position is determined.

[0088] In the embodiments of the present disclosure and other possible embodiments, the determining the azimuth information of the optical fiber 1 at the set target formation position based on the plurality of temperature values of the heating element 3 at different underlying depths and the set temperature value includes: using a controller to respectively calculate a plurality of differences between the plurality of temperature values at different underlying depths and the set temperature value; and based on the plurality of differences and a preset difference, determining the optical fiber depth information along the sleeve 6 and the plane position information perpendicular to the plane corresponding to the optical fiber depth information in the azimuth information of the optical fiber 1 at the set target formation position.

[0089] In the embodiments of the present disclosure and other possible embodiments, using the cable 4 connected to the detection mechanism 5 to control the detection mechanism 5 to fall in the sleeve 6 to the set depth corresponding to the set target formation position at the initially set first set speed includes: using the cable 4 connected to the detection mechanism 5 to control the fall in the sleeve 6 at the initially set first set speed, and obtaining the real-time depth at which the detection mechanism 5 falls in the sleeve 6; calculating in real time the deviation between the real-time depth and the set depth, and adjusting the speed corresponding to the real-time depth based on the deviation, and using the adjusted speed, using the cable 4 connected to the detection mechanism 5 to control the detection mechanism 5 to fall in the sleeve 6 until the real-time depth is equal to the set depth or the deviation between the real-time depth and the set depth is within the set depth deviation range.

[0090] In the embodiment of the present disclosure, when the controller controls the detection mechanism 5 to fall in the sleeve 6 to the set depth corresponding to the set target formation position at the initially set first set speed, after the induction switch 7 senses the detection mechanism 5, the heating element 3 generates heat.

[0093] In the embodiment of the present disclosure and other possible embodiments, the perforating instrument is configured with an azimuth sensor, and the azimuth information of the optical fiber 1 at the set target formation position is obtained by using the azimuth sensor, and the set target formation is perforated at other azimuths outside the azimuth information.

[0094] The present disclosure can use advanced sensors and algorithms to monitor the position and azimuth of the optical fiber 1 outside the casing 6 in real time. Through precise measurement and calculation, the position of the optical fiber outside the pipe in the perforation section (reservoir) can be accurately located. For horizontal wells, its phase can be determined. This technical solution can not only solve the problem of positioning the optical fiber outside the pipe, but also significantly improve the success rate of optical fiber logging. By accurately positioning the optical fiber outside the pipe, we can obtain more reliable and accurate logging data. This will help engineers better understand the reservoir characteristics and make more informed decisions. Specifically, by solving the problem of positioning the optical fiber outside the pipe in permanent optical fiber logging outside the casing, the success rate of logging is improved, and the azimuth of the optical fiber outside the pipe in the perforation section (reservoir) can be accurately located, and the phase for horizontal wells.

[0096] 1) The correct recognition rate of the instrument reaches 100%: One of the keys to accurate positioning. In the thermal imaging positioning technical solution for avoiding shooting of the optical fiber outside the casing, the position of the optical fiber can be accurately mapped onto the image, and it has a 100% correct recognition rate in a variable and complex environment. This means that petroleum engineers and technicians can more reliably understand the position of the optical fiber outside the casing, thereby providing accurate reference for subsequent logging operations.

[0097] 2) The temperature signal detection efficiency reaches 100%: ensuring the success of logging. In addition to the correct recognition rate of the instrument, the temperature signal detection efficiency is also one of the key factors in the permanent optical fiber outside-casing avoidance thermal imaging positioning method. This method can ensure that the signal transmission and detection success rate reach 100%. This means that during the actual optical fiber logging process, engineers can obtain accurate and stable signals from the optical fiber, and then conduct precise measurement and analysis of the oil layer.
