Detailed implementation manners

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0031] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "inner" and "outer" is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "installed" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0033] In the prior art, when using the gas lift lifting scheme for oil production, the gas lift ball needs to sink to the bottom of the well each time, and the liquid column height lifted by each gas lift ball in a single lift is the immersion height of the entire oil. The liquid column height lifted in a single lift is relatively large, and the required lifting force is also greater, which makes the starting pressure of the gas lift device need to be large enough.

[0034] In order to overcome the defects in the prior art, this embodiment proposes an intelligent short joint for a golf ball gas lift oil production system, which is used to connect the two vertical sections of the U-shaped oil pipe, so that the gas lift ball can start the lifting operation at any depth of the oil pipe, which is beneficial to controlling the liquid column height lifted by each gas lift ball in a single lift, reducing the starting pressure of the lifting device, saving energy consumption, and improving the oil production efficiency. And it is beneficial to extend the service life of the lifting device.

[0035] Combined with Figures 1 to 6, the intelligent joint 100 of the golf ball gas lift oil production system provided by the embodiment of the present utility model includes a valve body 110 and a baffle 120. The valve body 110 is provided with a first through hole 111, a second through hole 112, and a guiding through hole 113 for communicating the first through hole 111 and the second through hole 112. The first through hole 111 is used to communicate with the first pipeline 210, and the second through hole 112 is used to communicate with the second pipeline 220. The baffle 120 is movably installed on the valve body 110 to open or close the guiding through hole 113. In the open state of the guiding through hole 113, the gas lift ball can pass through. The gas lift ball can enter the second through hole 112 from the first through hole 111 through the guiding through hole 113, and the running directions of the gas lift ball in the first through hole 111 and the second through hole 112 are opposite, so that the gas lift ball can transport the fluid in the second pipeline 220 communicated with the second through hole 112. After adopting the intelligent joint 100 of the golf ball gas lift oil production system, the gas lift ball can turn back from any position of the second pipeline 220 for fluid lifting, which is beneficial to reducing the starting pressure of the lifting device and improving the efficiency.

[0036] Optionally, the intelligent joint 100 of the golf ball gas lift oil production system further includes a driving member (not shown in the figure) connected to the baffle 120. The driving member drives the baffle 120 to move axially along the first through hole 111 or the second through hole 112; alternatively, the driving member drives the baffle 120 to rotate.

[0037] In this embodiment, the driving member can adopt a motor. The motor can drive the baffle 120 to move axially along the valve body 110. The axial direction of the valve body 110 is the axial direction of the first through hole 111 or the second through hole 112. The baffle 120 can perform a telescopic movement along the axial direction of the valve body 110. When the baffle 120 extends into the guiding through hole 113, the guiding through hole 113 is closed, and at this time, the gas lift ball cannot enter the second through hole 112 from the first through hole 111 through the guiding through hole 113. When the baffle 120 retracts from the guiding through hole 113, the guiding through hole 113 is opened, and at this time, the gas lift ball can smoothly enter the second through hole 112 from the first through hole 111 through the guiding through hole 113. In this way, the gas lift ball can start the lifting operation at the depth position where the second through hole 112 is located and lift the fluid in the second pipeline 220 communicated with the second through hole 112 to the ground.

[0038] Of course, in some other embodiments, the baffle 120 can also be rotated to open and close the through hole 113. For example, when the through hole 113 is in the closed state, the baffle 120 is vertically placed, approximately parallel to the axis of the first through hole 111 or the second through hole 112. When it is necessary to open the through hole 113, the motor drives the baffle 120 to rotate about 90 degrees, so that the baffle 120 is perpendicular to the axis of the first through hole 111 or the second through hole 112. In this way, the opening and closing of the through hole 113 can also be achieved. When the through hole 113 is in the open state, the air lift ball can enter the second through hole 112 from the first through hole 111 through the through hole 113.

[0039] Of course, in some embodiments, the rotation angle of the baffle 120 is not limited to 90 degrees, and can be any angle between 50 degrees and 80 degrees, as long as the air lift ball can enter the through hole 113 from the first through hole 111.

[0040] Combined with Figure 7 and Figure 8 , optionally, a sensor 130 is provided on the valve body 110. The number and type of the sensor 130 are not limited. According to actual needs, one, two, three, four, five or more sensors 130 can be provided. The types of detection parameters of the sensor 130 include but are not limited to detecting pressure, temperature, counting, depth, current, voltage, gas concentration, etc.

[0041] Optionally, an installation groove 131 is formed on the valve body 110, and the sensor 130 is arranged in the installation groove 131. A cover plate 133 is provided at the notch of the installation groove 131 to protect the sensor 130.

[0042] Optionally, a power connection terminal 140 is provided on the valve body 110. The power connection terminal 140 can be powered by a cable or a battery. The power connection terminal 140 can supply power to the driving member, the sensor 130, etc. In this embodiment, the power connection terminal 140 adopts a pluggable quick connector, which is convenient for installation and electrical connection. It should be noted that the power connection terminal 140 can be used for connecting the power line or the communication line, and no specific limitation is made here.

[0043] Optionally, a number of balls 150 are provided on the outer surface of the valve body 110. In the actual application scenario, the valve body 110, the first pipeline 210 and the second pipeline 220 are all located in the casing. That is, the outer surface of the valve body 110 may come into contact with other pipe walls or objects. By providing the balls 150, the frictional resistance can be reduced, and the wear on the surface of the valve body 110 can be reduced. In this embodiment, the balls 150 are rotatably installed on the valve body 110, and can rotate at any angle, and are evenly spaced on the surface of the valve body 110, which is beneficial to reducing the frictional resistance and improving the wear resistance of the valve body 110.

[0044] It is easy to understand that after the pipeline and the valve body 110 are assembled, they are then lowered to the bottom of the well. Due to the arrangement of the balls 150, it is beneficial to reduce the resistance of the pipeline during lowering, and the effect is better than that of traditional centralizers.

[0045] Optionally, a floating connector (not shown in the figure) is provided in the first through hole 111 and / or the second through hole 112, and the floating connector is used to connect to the first pipeline 210 and / or the second pipeline 220. At least one of the first through hole 111 and the second through hole 112 is provided with a floating connector. In this embodiment, floating connectors are provided at both ends of the first through hole 111 and the second through hole 112. The floating connectors are respectively connected to the first pipeline 210 and the second pipeline 220. The floating connector may include elastic members such as springs, which are mainly used to adapt to the installation tolerance of pipeline connection and avoid the problem that the positions are too different during installation and cannot be connected. The specific structural form of the floating connector is not limited as long as it can achieve length adjustment within a certain range.

[0046] Combined Figure 9 Moreover, an oil production system 200 according to an embodiment of the present invention is further provided, including a first pipeline 210, a second pipeline 220, and the intelligent short joint 100 of the golf ball gas lift oil production system as described above. The first pipeline 210 communicates with the first through hole 111, and the second pipeline 220 communicates with the second through hole 112.

[0047] Optionally, the first pipeline 210 and the second pipeline 220 respectively include multiple connected connecting pipes, and the intelligent short joint 100 of the golf ball gas lift oil production system is connected at the connection of adjacent connecting pipes.

[0048] It should be noted that when the depth of the oil well is relatively deep, the oil pipes are all installed by splicing multiple sections. In this embodiment, the first pipeline 210 includes multiple spliced first connecting pipes 211. The second pipeline 220 includes multiple spliced second connecting pipes 221.

[0049] One end of the first through hole 111 is connected to one of the first connecting pipes 211 of the first pipeline 210, and the other end of the first through hole 111 is connected to another first connecting pipe 211 of the first pipeline 210. Floating connectors can be respectively provided at both ends of the first through hole 111. Similarly, one end of the second through hole 112 is connected to one of the second connecting pipes 221 of the second pipeline 220, and the other end of the second through hole 112 is connected to another second connecting pipe 221 of the second pipeline 220. Floating connectors can be respectively provided at both ends of the second through hole 112.

[0050] Installing the double-pipe communication valve at the splicing point of the pipeline can not only realize the assembly and axial communication of two adjacent sections of the pipeline, but also realize the transverse communication of different pipelines. There is no need to additionally drill holes in the first pipeline 210 and the second pipeline 220 at the starting position of the gas lift ball lifting operation, and the improvement cost is lower.

[0051] In this embodiment, the first pipeline 210 and the first through hole 111 are connected by threads. The second pipeline 220 and the second through hole 112 are connected by threads. Of course, flange connection or other fixed connection methods can also be used, which are not specifically limited here.

[0052] Optionally, a plurality of intelligent joints 100 for golf ball gas lift oil production systems are arranged at intervals on the first pipeline 210 and the second pipeline 220. For example, a double-pipe connecting valve can be arranged at a certain depth interval. According to the actual downhole depth and downhole fluid conditions, the guide through holes 113 of some of the intelligent joints 100 for golf ball gas lift oil production systems are controlled to be in an open state, and the guide through holes 113 of some of the intelligent joints 100 for golf ball gas lift oil production systems are controlled to be in a closed state. Or control the guide through holes 113 of all the intelligent joints 100 for golf ball gas lift oil production systems to be in an open state.

[0053] Optionally, the oil production system 200 further includes a separator 235, a cleaner 230, a ball launcher 240, and an injection pipe 250. The ball launcher 240 and the injection pipe 250 are respectively connected to the first pipeline 210. The ball launcher 240 launches a gas lift ball into the first pipeline 210, and the injection pipe 250 injects high-pressure gas into the first pipeline 210. The high-pressure gas is used to push the gas lift ball to move. The gas lift ball moves downward along the first pipeline 210, enters the second pipeline 220 from the bottom of the U-shaped oil pipe or the guide through hole 113 of the intelligent joint 100 for golf ball gas lift oil production system, moves upward along the second pipeline 220, and lifts the liquid column in the second pipeline 220 to the ground. After the liquid and the gas lift ball reach the ground, they enter the separator 235 for separation. The separated gas lift ball enters the cleaner 230 for cleaning, and the cleaned gas lift ball enters the ball launcher 240 again to prepare for the next launch.

[0054] Optionally, a liquid inlet pipe 260 is connected to the bottom of the U-shaped oil pipe. The liquid inlet pipe 260 is used to introduce the liquid in the formation into the U-shaped oil pipe. A check valve 261 is provided on the liquid inlet pipe 260 to ensure that the liquid in the formation can only flow into the U-shaped oil pipe unidirectionally.

[0055] The operation principle of the oil production system 200 with the intelligent joint 100 for golf ball gas lift oil production system provided in this embodiment is as follows:

[0056] The first pipeline 210 and the second pipeline 220 are connected near the bottom of the well to form a U-shaped structure. The gas lift ball moves downward from the first pipeline 210 to the bottom of the well under the pushing action of the compressed gas and reaches the bottom of the second pipeline 220. The outer diameter of the gas lift ball is adapted to the inner diameters of the first pipeline 210 and the second pipeline 220, and it can move smoothly in the first pipeline 210 and the second pipeline 220. The gap between the gas lift ball and the inner wall of the pipeline is almost zero, preventing fluid from leaking from the gap during the lifting process.

[0057] The gas lift device includes a compressor, and the high-pressure gas uses natural gas or nitrogen. In the absence of the intelligent sub-section 100 of the golf ball gas lift oil production system, the high-pressure gas coming out of the compressor is injected into the first pipeline 210, driving the gas lift ball in the first pipeline 210 to move downward and reach the bottom of the second pipeline 220. The gas lift ball continues to move upward along the second pipeline 220 under the push of the high-pressure gas, lifting the fluid in the second pipeline 220 to the wellhead.

[0058] If the intelligent sub-section 100 of the golf ball gas lift oil production system is connected between the first pipeline 210 and the second pipeline 220, and the intelligent sub-sections 100 of the golf ball gas lift oil production system are installed at different depth positions respectively. Assume the bottom hole depth is 2 kilometers. According to the actual operation situation, control the guide through hole 113 of the intelligent sub-section 100 of the golf ball gas lift oil production system at a depth of 1 kilometer to be in the open state. When the gas lift ball is moving downward along the first pipeline 210 and before the gas lift ball reaches the bottom hole, it can enter the second pipeline 220 from the guide through hole 113 of the intelligent sub-section 100 of the golf ball gas lift oil production system. In this way, the gas lift ball can start to move upward from 1 kilometer below the well, lifting the liquid column above 1 kilometer below the well in the second pipeline 220 to the wellhead. At this time, the pressure of the high-pressure gas only needs to meet the requirement of lifting the liquid column above 1 kilometer below the well in the second pipeline 220 to the wellhead, which is much smaller than the gas lift pressure required to lift the liquid column above 2 kilometers below the well to the wellhead. In this way, the power requirement for the compressor is smaller, the starting pressure is lower, the cost is lower, and it is beneficial to extend the service life of the compressor.

[0059] Of course, since the intelligent sub-sections 100 of the golf ball gas lift oil production system are provided at different depths respectively, it is possible to select the gas lift ball to start the return lifting operation from any one of the intelligent sub-sections 100 of the golf ball gas lift oil production system, which is beneficial to improving the operation efficiency and can improve the operation flexibility according to the actual working conditions.

[0060] In summary, the intelligent sub-section 100 of the golf ball gas lift oil production system and the oil production system 200 provided by the embodiments of the present invention have the following beneficial effects, including:

[0061] The intelligent sub-section 100 of the golf ball gas lift oil production system and the oil production system 200 provided by the embodiments of the present invention can install the intelligent sub-section 100 of the golf ball gas lift oil production system at any depth position of the oil pipe, which is convenient for controlling the height of the liquid column lifted by the gas lift ball each time. The gas lift ball can start the lifting operation at any depth position and does not need to sink to the bottom hole every time. It is beneficial to improve the lifting efficiency, reduce the starting pressure of the gas lift device, and extend the service life of the gas lift device.

[0062] It should be noted that, without conflict, the features in the embodiments of this application can be combined with each other.

[0063] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
