Description

Technical Field

[0001] This invention relates to the field of reservoir stimulation in oil and gas field development, and particularly to a method and apparatus for inter-layer temporary sealing and diversion construction. Background Technology

[0002] For ultra-deep and extremely thick reservoirs, early stimulation methods primarily involved general, all-encompassing stimulation of the entire wellbore. However, due to the strong vertical heterogeneity of the reservoirs and the uneven development of natural fractures, general stimulation methods failed to achieve uniform vertical stimulation of the extremely thick reservoirs, thus failing to fully utilize the production capacity of each oil and gas layer, resulting in poor post-fracturing effects and an inability to maximize production capacity. Currently, improving the vertical recovery of extremely thick reservoirs is mainly achieved through stratified stimulation. Various stratified stimulation technologies have been developed to suit different reservoir conditions and completion string structures. These include the use of various mechanical tools (bridge plugs, sliding sleeve packers, coiled tubing hydraulic jetting, etc.) for stratified stimulation; and non-mechanical stratified stimulation techniques such as temporary plugging stratified stimulation, extreme flow restriction stratified stimulation, and various chemical plug stratified stimulation methods.

[0003] In response to the extreme working conditions of ultra-deep, ultra-high temperature, and ultra-high pressure in the Kuqa piedmont area, mechanical stratification operations are characterized by long cycles, high costs, and significant construction risks. Currently, the main approach is to use inter-layer temporary plugging and diversion to improve the vertical modification level. The temporary plugging and diversion process involves adding a certain concentration of combined temporary plugging balls to the fracturing fluid. During pumping, these balls reach the fracture opening, forming a temporary plug and preventing subsequent fluid from entering the formation. In other words, by sealing the fracture connected to the perforation orifice, the continuous fluid inflow into the orifice is prevented, indirectly creating a temporary plug on the perforation orifice.

[0004] Currently, the main methods for evaluating the effectiveness of temporary damming and diversion are direct and indirect methods. Direct assessment methods for ultra-deep formations (microseismic, fiber optic, etc.) suffer from low monitoring accuracy, high cost, and poor monitoring results due to the influence of high temperature and pressure. Indirect methods primarily rely on parameters such as changes in surface construction pressure during the diversion process, changes in crack propagation pressure before and after temporary damming and diversion, and changes in instantaneous pump shutdown pressure before and after temporary damming and diversion. Simply evaluating the success or failure of the diversion based on pressure changes often involves strong subjectivity, significantly reducing the accuracy of the evaluation results. Therefore, there is an urgent need for a method that can rapidly and quantitatively evaluate the effectiveness of temporary damming and diversion without the need for auxiliary monitoring technologies, to guide on-site temporary damming and diversion construction. Summary of the Invention

[0012] Preferably, the calculation of the temporary plugging efficiency based on the temporary plugging pressure and the stress of each perforation cluster includes:

[0013] Determine the minimum value of the minimum horizontal principal stress corresponding to all perforation clusters;

[0014] The sum of the minimum value and the temporary suffocation pressure is used as the judgment threshold;

[0015] The minimum horizontal principal stress corresponding to each perforation cluster is compared with the determination threshold in turn;

[0016] If the minimum horizontal principal stress corresponding to the perforation cluster is greater than the determination threshold, then the perforation cluster is determined to have liquid ingress; otherwise, the perforation cluster is determined not to have liquid ingress.

[0017] The ratio of the number of inlet perforation clusters to the total number of perforation clusters is used as the temporary plugging efficiency.

[0018] Preferably, determining whether to continue the temporary blocking and turning construction based on the temporary blocking efficiency includes: when it is determined that the temporary blocking efficiency is greater than a preset value, determining that there is no need to continue the temporary blocking and turning construction; otherwise, repeating the turning construction until the temporary blocking efficiency is greater than the preset value.

[0019] A second aspect of the present invention provides an inter-layer temporary sealing and turning construction system, comprising:

[0031] The ratio of the number of inlet perforation clusters to the total number of perforation clusters is used as the temporary plugging efficiency.

[0032] A third aspect of the present invention provides a computer-readable storage medium storing a computer program or instructions; when the computer program or instructions are executed by a processor, they are at least used to implement the above-described method.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] First, this invention enables a quantitative evaluation of the diversion effect. Traditional calculation methods rely solely on changes in surface construction pressure to determine the success or failure of the diversion, lacking a quantitative standard for success or failure and failing to establish a relationship between the diversion effect and the plugged perforation clusters. This invention, by observing changes in surface construction pressure during the diversion phase and combining this with the minimum horizontal principal stress value of the perforation clusters, characterizes the specific number of perforation clusters that have entered the reservoir after temporary plugging. Instead of simply judging the diversion effect as success or failure, it calculates the temporary plugging efficiency, achieving a quantitative characterization of the diversion effect. Second, this invention can also guide on-site diversion construction. When microseismic monitoring data is unavailable, traditional methods rely solely on changes in surface construction pressure to guide on-site construction. The lack of a quantitative evaluation of the diversion effect introduces significant risks and uncertainties into on-site diversion guidance. This invention calculates the ratio of the number of perforation clusters that entered the reservoir at the end of the diversion to the total number of perforation clusters. When the calculated temporary plugging efficiency is low, it can guide adjustments to the on-site diversion agent, allowing for another diversion attempt. If the temporary plugging efficiency reaches the desired value after the diversion, the next stage of reservoir stimulation can proceed.

[0035] Compared with conventional direct evaluation methods, the analytical method of this invention has high reliability and effectiveness, can achieve real-time and quantitative evaluation of the diversion effect, and can also be used to guide on-site diversion construction. It has short operation time, reduced construction risks, and low operating costs, and can provide a scientific basis for improving the temporary plugging diversion process of ultra-deep and thick reservoirs.

[0036] In the next few years, deep natural gas production will account for more than 50% of total natural gas production, becoming an important replacement resource for natural gas production. Therefore, there is a strong demand for evaluation and optimization of the inter-layer temporary plugging and diversion effect in ultra-deep and thick reservoirs. As approximately 150 deep wells need to undergo fracturing and acidizing annually, real-time evaluation and guidance of the optimization of on-site temporary plugging and diversion construction can improve the post-fracturing stimulation effect. At the same time, it can also guide the optimization of the temporary plugging scale of adjacent wells in the same block, saving construction costs and further improving the stimulation effect of ultra-deep reservoirs. Based on the optimization of on-site temporary plugging and diversion construction, the production after stimulation is 2-3 times higher than that of adjacent wells, resulting in significant economic benefits.

[0037] In summary, the method for evaluating the inter-layer temporary plugging and diversion effect provided by this invention quantitatively assesses the temporary plugging effect through the fluid injection efficiency of the perforation cluster. The main technical problem it solves is the poor real-time monitoring of the diversion effect when auxiliary monitoring technologies are lacking. Without the need for auxiliary monitoring technologies, the method allows for rapid and quantitative evaluation of the inter-layer temporary plugging and diversion effect, guiding successful on-site temporary plugging operations and providing a scientific basis for improving the temporary plugging and diversion process in ultra-deep and extremely thick reservoirs.

[0038] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0046] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0047] To address the challenge of lacking auxiliary monitoring technologies for real-time monitoring of diversion effects in deep reservoirs and to achieve real-time and quantitative evaluation of diversion effects in ultra-deep and extremely thick reservoirs, this invention provides a method for evaluating the diversion effect of inter-layer temporary plugging. The core of this invention has three aspects: First, based on well logging data and using geostress interpretation software, the minimum horizontal principal stress profile of the target segment in the longitudinal direction of the fracturing well is calculated, and the perforation depth of each perforation cluster and the minimum horizontal principal stress at that depth are marked. Second, on the fracturing operation curve, the surface operation pressures before and after temporary plugging, specifically the first surface operation pressure P1 and the second surface operation pressure P2, are accurately read under the same flow rate. Third, based on the relationship between the stress difference between each perforation cluster and the difference in surface operation pressure before and after temporary plugging, the fluid absorption situation after temporary plugging of each perforation segment can be determined, thereby obtaining the temporary plugging efficiency of the well after adding the temporary plugging agent. This allows for the assessment of the diversion effect after temporary plugging, guiding the adjustment of the diversion agent in the field and determining whether to perform another diversion operation.

[0048] Figure 1 The interlayer temporary sealing and turning construction method provided by this invention includes:

[0049] S101. Calculate the stress of each perforation cluster based on the logging data;

[0050] S102. Calculate the temporary plugging pressure after the temporary plugging agent enters the perforation orifice;

[0051] S103. Calculate the temporary plugging efficiency based on the temporary plugging pressure and the stress of each perforation cluster;

[0052] S104. Determine whether to continue the temporary blocking and turning construction based on the temporary blocking efficiency.

[0053] According to some embodiments of the present invention, the stress of each perforation cluster is calculated based on logging data, including: calculating the minimum horizontal principal stress profile of the target section of the fractured well in the longitudinal direction based on the logging data, and marking the perforation depth of each perforation cluster and the minimum horizontal principal stress at that depth; wherein the logging data includes density logging data, sonic logging data, gamma logging data and spontaneous potential logging data.

[0054] According to some embodiments of the present invention, the calculation of the temporary plugging pressure after the temporary plugging agent enters the perforation orifice includes: reading the ground construction pressure before and after temporary plugging under the same construction displacement according to the fracturing construction curve, and taking the difference between the two as the temporary plugging pressure.

[0055] According to some embodiments of the present invention, the temporary plugging efficiency is calculated based on the temporary plugging pressure and the stress of each perforation cluster, including: determining the minimum value of the minimum horizontal principal stress corresponding to all perforation clusters; using the sum of the minimum value and the temporary plugging pressure as a judgment threshold; sequentially comparing the minimum horizontal principal stress corresponding to each perforation cluster with the judgment threshold; if the minimum horizontal principal stress corresponding to the perforation cluster is greater than the judgment threshold, then the perforation cluster is determined to have fluid ingress; otherwise, the perforation cluster is determined not to have fluid ingress; the ratio of the number of perforation clusters with fluid ingress to the total number of perforation clusters is used as the temporary plugging efficiency. When the temporary plugging efficiency is determined to be greater than a preset value, it is determined that there is no need to continue the temporary plugging diversion construction; otherwise, the diversion construction is repeated until the temporary plugging efficiency is greater than the preset value.

[0056] According to some embodiments of the present invention, the interlayer temporary sealing and reversing construction method includes:

[0057] Step 1: Import the logging data into software such as Fracpro, Gohfer, and StimPlan. Using the geostress interpretation module of these software, calculate the minimum horizontal principal stress profile of the target section in the longitudinal direction of the fractured well, and mark the perforation depth of each perforation cluster and the minimum horizontal principal stress at that depth. It should be noted that the logging data of the fractured well mentioned in this step includes at least: density logging, sonic logging, gamma logging, and spontaneous potential logging.

[0058] Step 2: On the fracturing operation curve, accurately read the first surface construction pressure P1 before temporary plugging and the second surface construction pressure P2 after temporary plugging, under the same operation displacement. The first surface construction pressure P1 and the second surface construction pressure P2 are the surface construction pressures during the turning process. The process of the temporary plugging agent sealing the perforation is the process by which fluid enters the channel of the formed hydraulic fracture, and the perforation continuously shrinks, thus increasing the friction of the perforation orifice and ultimately causing a change in the surface construction pressure.

[0059] Step 3: Calculate the difference between the second surface construction pressure P2 and the first surface construction pressure P1, which is the temporary plugging pressure P after the plugging agent enters the perforation. Simultaneously, according to the principle of minimum seepage resistance, fluid always enters along the perforation cluster with the least seepage resistance. Therefore, mark the perforation cluster with the lowest horizontal principal stress among the multiple perforation clusters in the fracturing well as the main fluid entry section. The sum of the minimum horizontal principal stress value of this perforation cluster and the temporary plugging pressure P is denoted as P0. If P0 is greater than the minimum horizontal principal stress of other perforation clusters, it is considered that the perforation cluster has fluid entering after temporary plugging; if P0 is less than the minimum horizontal principal stress of other perforation clusters, it is considered that the perforation cluster has no fluid entering after temporary plugging. The temporary plugging efficiency can be calculated based on the ratio of the number of perforation clusters that have fluid entering after temporary plugging to the total number of perforation clusters. The theoretical basis for this step is that wells with higher directional pressure have better temporary plugging efficiency because when the fluid first enters the perforation section with the least geostress, the perforation section that initially absorbs the fluid is blocked as the temporary plugging agent is added. The fluid then enters the perforation section with higher geostress. The higher the directional pressure, the more the fluid can overcome the greater stress difference between the perforation sections, thus entering more perforation sections, and the better the temporary plugging efficiency.

[0060] Step 4: If the temporary plugging efficiency is greater than 60%, the next stage of reservoir stimulation construction can be carried out directly; if the temporary plugging efficiency is less than 60%, it indicates that the temporary plugging effect is poor. The amount of temporary plugging agent should be adjusted on site, and another turning operation should be carried out until the temporary plugging efficiency is greater than 60%.

[0061] The technical solution of the present invention will be further described below with reference to the embodiments.

[0062] The example well, KS2-18, is located in the Kelasu structural zone of the Kuqa Depression, with a total drilling depth of 6897.6m. The completed formation is the Cretaceous Bashkichik Formation. The section to be stimulated ranges from 6676 to 6858m, a significant span of 182m. A total of 13 perforations were drilled. The natural fractures are highly heterogeneous, making uniform stimulation difficult. Therefore, temporary plugging and layered stimulation were employed to achieve sufficient vertical stimulation of the reservoir. The steps of temporary plugging and layered stimulation included:

[0063] Step 1: Import the logging data from well KS2-18, including density logging, sonic logging, gamma logging, and spontaneous potential logging, into Gohfer fracturing software. Using the software's geostress interpretation module, calculate the minimum horizontal principal stress profile of the target section in the vertical direction, and mark the perforation depth of each perforation cluster and the minimum horizontal principal stress at that depth. Figure 2 As shown in the figure, the dark rectangular blocks represent perforation clusters. The minimum horizontal principal stress of each perforation cluster in well ks2-18 is calculated and shown in Table 1.

[0064] Table 1

[0065]

[0066] Step Two: Figure 3 The example well KS2-18 is shown in the fracturing operation curve. On this curve, stage A represents the pre-plugging stage, stage B represents the plugging stage, and stage C represents the post-plugging stage. After stage A is completed, 90 kg of 1-5 mm plugging balls and 45 kg of 5-10 mm plugging balls are deployed. After the combined plugging balls reach the bottom of the well, the operating pressure increases, and the displacement of the same operation rate is accurately measured at 1 m³ / h. 3 At a pressure of 6000 MPa / min, the first ground construction pressure P1 before temporary plugging is 58.4 MPa, and the second ground construction pressure P2 after temporary plugging is 61.5 MPa.

[0067] Step 3: Calculate the difference between the second surface construction pressure P2 and the first surface construction pressure P1, which is the temporary plugging pressure P after the temporary plugging agent enters the perforation. The temporary plugging pressure P is 3.1 MPa. According to Table 1, the minimum horizontal principal stress of the perforation cluster in well ks2-18 is 109.8 MPa for the first cluster. During construction, the fluid mainly enters this perforation section. After adding the temporary plugging agent, the fluid is forced to divert and temporarily deflect. The sum of the minimum horizontal principal stress value of this perforation cluster and the temporary plugging pressure P, P0, is 112.9 MPa. Since the maximum stress difference between the perforation clusters in well ks2-18 is 4.4 MPa between the first and eighth clusters, which is greater than the temporary plugging deflection pressure P of 3.1 MPa, the fluid can only enter a portion of the perforation section after temporary plugging. Calculations showed that the perforation clusters smaller than P0 were clusters 1, 3, 4, 5, 9, 10, 11, 12, and 13, a total of 9 perforation clusters. All of these clusters were able to allow fluid to enter after temporary plugging. Based on the ratio of the number of perforation clusters that allowed fluid to enter after temporary plugging to the total number of perforation clusters, the temporary plugging efficiency of well ks2-18 was calculated to be 69.2%.

[0068] Step 4: The temporary plugging efficiency is greater than 60%, which achieves the effect of temporary plugging and stratified modification. The next stage of reservoir modification construction can be carried out directly.

[0070] In addition, the present invention also provides a computer-readable storage medium 1100, which stores a computer program or instructions that, when executed by a processor, are used to implement at least the above-described interlayer temporary sealing and turning construction method.
