Description

Technical Field

[0001] The present application relates to the field of oil production engineering, and in particular to a method, device and storage medium for real-time determination of successful fire drive ignition. Background Art

[0002] Fire drive technology is an important thermal recovery method for heavy oil. It continuously injects air into the formation through the gas injection well and ignites the oil formation to achieve combustion in the formation, thereby pushing the formation crude oil from the gas injection well to the production well. Whether the fire drive is ignited successfully will directly affect the implementation effect of the fire drive. At present, the success of fire drive ignition in domestic heavy oil is mainly judged by the downhole temperature of the gas injection well during the ignition period and the change in CO2 content in the corresponding oil well output gas; however, the temperature, pressure, and oil properties of ordinary heavy oil reservoirs are different from those of heavy oil. Due to the low viscosity of crude oil and the relatively high formation pressure, CO2 in the output gas is easy to dissolve in the output oil. The change in CO2 content cannot be used as a basis for judging the success of ordinary heavy oil fire drive ignition.

[0003] Guan Wenlong et al. used one-dimensional and three-dimensional fire-burned oil layer oil recovery physical simulation experimental devices (Guan Wenlong, Ma Desheng, et al. Experimental study on the characteristics of fire-driven reservoir zones [J]. Acta Petrolei Sinica, 2010, 31(1): 101-109.) to study the macroscopic thermodynamic characteristics of each formation zone during the fire-driven process of vertical wells in heavy oil reservoirs and the distribution laws of pressure field, temperature field and saturation field. The heavy oil fire-driven reservoir was divided into five zones from the injection end to the production end: the burned zone, the fire wall, the coking zone, the oil wall and the residual oil zone. However, the device does not involve a method for determining the success of the ignition of ordinary heavy oil fire-driven.

[0004] Wang Ruyan and others used fire drive monitoring technologies such as downhole temperature and pressure monitoring technology, fire drive output gas monitoring technology, and fire line front monitoring technology in the Xinjiang Hongqian fire drive test area (Wang Ruyan, Pan Jingjun, et al. (2015) Series of research and application of fire drive monitoring technology in heavy oil reservoirs - taking the Xinjiang Hongqian fire drive test area as an example. 2015 International Conference on Oil and Gas Field Exploration and Development, Xi'an), and timely and effectively grasped the formation combustion status, combustion front advancement direction, fire line spread range, output gas composition and other information during the fire drive process, so as to better carry out dynamic control and development adjustment of fire drive production. However, this technology does not involve the problem of real-time determination of the success of ignition of ordinary heavy oil fire drive.

[0005] Wang Guofu et al. studied a microseismic monitoring operation method for the burning zone of the oil layer (patent publication number CN104181602A). The invention uses microseismic monitoring technology, with the help of microseismic mechanism and microseismic density, to analyze the distribution of the burning area and the front edge area, and uses the distribution of microseismic points to describe the fracture morphology and direction, and makes a velocity model based on the oil field acoustic logging data, and accurately locates to achieve the evaluation of the fire drive oil production effect, and provide a basis for the regulation of fire drive oil production. However, this technology does not involve the problem of real-time determination of the success of ordinary heavy oil fire drive ignition.

[0006] Wei Lulu et al. studied a method for identifying fault activity in underground gas storage based on microseismic monitoring technology (patent publication number CN113253343A). This method is based on microseismic monitoring results and uses microseismic event attribute information to calculate the fault activity index of different clusters of microseismic events. It can effectively identify fault activity during the injection and production process of underground gas storage, prevent the risk of sealing failure of fault activity in gas storage, and ensure the safe operation of gas storage. However, this technology does not involve the use of microseismic technology to determine in real time whether the ignition of heavy oil fire drive is successful or not.

[0007] Zhang Chunlong et al. studied a method for microseismic monitoring of gas storage (patent publication number CN113848585A). The method mainly obtains the monitoring results of the horizontal axis displacement detected by the laser rangefinder in the offset monitoring component, the vertical axis pressure detected by the pressure sensor, and the amplitude detected by the detector in the vibration monitoring component through the acquisition module, and the analysis module analyzes the monitoring results, determines to correct the monitoring results according to the comparison results of the monitoring results and the historical monitoring results, and calculates the early warning value sent by the sending module to the monitoring center according to the corrected monitoring results. It is used to overcome the problem that the monitoring process cannot be accurately controlled and adjusted according to the real-time monitoring data and historical data in the prior art, resulting in inaccurate monitoring of microseisms. However, this technology does not involve the use of seismic technology to determine in real time whether the fire drive is successfully ignited.

[0008] Ma Shou et al. studied a method for controlling balanced fracturing of shale gas wells (patent publication number CN112983379A). This method combines the separately applied microseismic monitoring technology, volume fracturing technology and variable aperture perforating technology for the first time to perform fracturing of shale gas wells, forming a new type of improved fracturing expansion form, increasing the fracturing transformation volume, and ultimately achieving improved fracturing effect and balanced fracturing of shale gas wells. However, this technology does not involve the use of microseismic monitoring technology to determine in real time whether the fire drive ignition is successful or not.

[0009] Zhao Lin et al. studied a method for monitoring the leading edge of reinjection well water based on microseismic monitoring technology (patent publication number CN110161566A). The method includes background monitoring. In the stopped state, the reinjection wellhead is used as the monitoring center and microseismic monitoring devices are evenly set around it to obtain background noise; normal reinjection monitoring, the reinjection wellhead is used as the monitoring center and microseismic monitoring devices are evenly set around it to obtain monitoring data and confirm the dominant direction of water; tracking monitoring, the monitoring center is set at a certain distance from the last monitoring center in the direction of the dominant axis of water, and microseismic monitoring devices are evenly set around the direction of the dominant axis of water for tracking monitoring. It solves the problem that the leading edge position of reinjection well water cannot be accurately monitored in the prior art. However, this technology does not involve the use of microseismic monitoring technology to determine whether the fire drive ignition is successful or not.

[0010] In summary, the existing microseismic monitoring technology is mainly used to identify fault activity, monitor hydraulic fracturing, water drive front, fire front, etc., but is not used to determine in real time whether the fire drive ignition is successful. Summary of the invention

[0064] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0065] Figure 1 A flowchart of a method for real-time determination of successful fire drive ignition provided in an embodiment of the present application.

[0066] The present application provides a method for real-time determination of successful fire drive ignition, the method comprising the steps of:

[0067] S1: Arrange monitoring equipment;

[0068] In an embodiment of the present application, the arrangement of monitoring equipment includes the steps of:

[0069] Determine the construction site;

[0070] Monitoring equipment is buried on the surface of the construction site.

[0071] Specifically, the monitoring equipment includes: a detector and a GPS positioning system. Multiple detectors and GPS positioning systems are buried on the surface around the construction site. The collection station mainly consists of a three-component detector, a data acquisition unit, and a GPS receiving system. The ground collection station is arranged in a dense array of rectangular arrays, and three-component detectors are used to receive underground microseismic shear and longitudinal wave signals.

[0072] S2: Obtaining original seismic wave data;

[0073] In the embodiment of the present application, the obtaining of original seismic wave data comprises the steps of:

[0074] Conduct background monitoring of construction sites;

[0075] Acquiring original microseismic signals of the construction site;

[0076] Performing spectrum analysis on the original microseismic signal.

[0077] Specifically, background monitoring should be carried out on the construction site before gas injection to obtain basic data and expand the signal-to-noise ratio of the signal response after the fluid change. The initial monitoring needs to ensure the shortest monitoring time.

[0078] S3: Obtain monitoring data;

[0079] In an embodiment of the present application, the acquisition of monitoring data comprises the steps of:

[0080] Conduct full-process monitoring of the construction site;

[0081] collecting microseismic waves at the construction site;

[0082] extracting microseismic parameters according to the microseismic waves;

[0083] The high-frequency seismic waves generated by thermal rupture at different combustion stages are captured according to the microseismic parameters.

[0084] Specifically, the construction site is monitored throughout the entire process, including the trial nitrogen injection stage, the pre-air injection stage, the continuous gas injection and ignition stage, and continuous monitoring after ignition. A dense ground array is used to collect microseismic waves and extract microseismic parameters every minute. Signal comparison and data processing can be used as the main basis for determining whether the ignition is successful.

[0085] In the embodiment of the present application, the whole process monitoring of the construction site includes the following steps:

[0086] Conduct nitrogen injection test phase monitoring on the construction site;

[0087] Conducting pre-air injection phase monitoring on the construction site;

[0088] Conducting continuous gas injection and ignition phase monitoring on the construction site;

[0089] The construction site is subjected to post-ignition monitoring.

[0090] S4: Compare the original seismic wave data with the monitored seismic wave data to determine the success of the fire drive ignition.

[0091] In the embodiment of the present application, the comparison of the original seismic wave data and the monitoring seismic wave data to determine the success of the fire drive ignition includes the following steps:

[0092] Compare the frequency signals at different stages before and after ignition;

[0093] Obtaining a combustion and explosion audio signal according to the comparison situation;

[0094] Determining whether the combustion and explosion audio signal is a high-frequency signal;

[0095] If so, the ignition is judged to be successful;

[0096] If not, it is judged that the ignition is unsuccessful.

[0097] Specifically, the seismic wave signal has a certain regularity, and the three-component detector can be used to jointly identify and determine the obvious start time of a new round of seismic waves. According to λ=u*T, u represents the wave velocity, which is determined by factors such as the physical properties of the formation. The location of the acquisition station does not change, the factors affecting the physical properties of the formation are the same, and the wave velocity is almost unchanged; T represents the period, and the start interval is short, indicating that the signal generated in the ignition stage is a high-frequency signal. In the gas injection stage, the wavelength of the seismic wave signal is longer, the wavelength interval is longer, and the frequency is lower; on the day of ignition, the frequency of the seismic wave signal increases, the wavelength interval is short, the start interval is short, and the signal generated is a high-frequency signal; in the combustion stage, if the same type of high-frequency seismic waves appear after ignition, it can be determined that the fire drive ignition is successful.

[0098] Embodiment 1:

[0099] In July 2022, a pilot test of fire drive development was carried out in the conglomerate reservoir of Menggulin Oilfield. The method was applied to determine the success of fire drive ignition, which mainly includes the following steps:

[0100] S1: Arrange monitoring equipment, such as Figure 5 As shown, 30 acquisition stations and 90 three-component geophones are arranged around the 6 injection and 22 production pilot areas of the Menggulin Oilfield. The distance between the acquisition stations is 250 meters, forming a dense array observation system covering an area of ​​about 1.25km2.

[0101] S2: Carry out background monitoring before gas injection in advance, obtain original seismic waves, and perform spectrum analysis on original microseismic signals;

[0102] S3: Conduct full-process monitoring, including the nitrogen test injection stage, the pre-air injection stage, the continuous gas injection ignition stage, and the continuous monitoring after ignition, starting from the gas injection stage before ignition and continuing until the end of ignition, for 60 days. Use dense arrays to collect high-frequency seismic wave signals generated during gas injection before ignition, during ignition, and after ignition, and analyze the changing patterns of seismic waves at different stages.

[0103] Figure 6 The figure shows the changes of seismic waves before and after ignition. By comparing the frequency signals at different stages before and after ignition, it can be determined that the combustion and explosion audio signals are high-frequency signals, and the ignition is successful. As can be seen from the figure, the wavelength of the seismic wave signal is longer in the gas injection stage, the wavelength interval is about 0.8s, and the frequency is lower; on the day of ignition, the frequency of the seismic wave signal increases, and a high-frequency signal is generated, the wavelength interval is about 0.475s, the start interval is short, and the signal generated is a high-frequency signal; in the combustion stage, the same type of high-frequency seismic waves appear 6 days after ignition, and the fire drive ignition is determined to be successful.

[0104] like Figure 7 By monitoring the downhole temperature changes of the gas injection well before and after ignition, it can be found that the temperature of the oil layer section reaches 260°C during ignition. After turning off the igniter, the temperature remains above 80°C, and the thermal radiation of the oil layer section is obvious.

[0105] like Figure 8 After the ignition is successful, the oil well will show effective reaction within 1 month at the earliest. The effective reaction is manifested by the continuous decrease of water content without drainage period, and the maximum decrease of water content can reach 60%. By analyzing the downhole temperature changes and the effective reaction of the oil wells in the 6 gas injection wells in Menggulin, it is shown that the 6 gas injection wells were successfully ignited at one time.

[0106] like Figure 2 The present application provides a device for real-time determination of success of fire drive ignition, comprising:
