Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas field fracturing flowback fluid processing, and in particular to an oil and gas field fracturing flowback fluid processing control method, device, equipment and storage medium. Background Art

[0002] The treatment of oil and gas field fracturing flowback fluid is a complex and critical process, involving a variety of treatment methods to ensure that the discharged wastewater meets environmental standards. In oil and gas field fracturing flowback fluid, fracturing fluid flowback means that after the fracturing fluid is injected into the ground, the purpose of fracturing is completed, and the remaining fracturing fluid must be returned to the ground for treatment or reuse. However, with the rapid development of oilfield chemicals, the on-site construction conditions have higher and higher requirements for fracturing fluids. Chelating agent-type corrosion and scale inhibition fracturing fluids meet the needs of the comprehensive development of oilfield additives in the future. In the current oilfield exploitation process, facing the problem of hydraulic fracturing using a large amount of water resources and serious pollution of fracturing flowback fluids, the reuse of flowback fluids is the future trend of the oil and gas field industry development, both from the perspective of cost and environmental protection.

[0003] At present, the main problem with the treatment of fracturing return fluid is the insufficient number of fracturing return fluid treatment equipment (cost and site limitations). Therefore, in actual engineering applications, a group of fracturing return fluid treatment equipment is usually used at several fracturing operation points. Although this solves the problem of insufficient quantity, it also leads to the need for coordination of fracturing return fluid treatment tasks with very high accuracy among multiple fracturing operation points. Otherwise, it will affect the fracturing operation tasks of multiple fracturing operation points and affect the production progress of the enterprise.

[0004] Therefore, how to improve the efficiency of fracturing backflow treatment, reduce the energy consumed in the treatment process, and maximize corporate benefits is a technical problem that needs to be solved urgently. Summary of the invention

[0018] According to the timestamp information at each moment and the corresponding fracturing flowback fluid discharge volume, the fracturing flowback fluid processing information of each fracturing operation point is generated.

[0019] Optionally, based on the fracturing flowback fluid processing information of each fracturing operation point, the fracturing flowback fluid processing task steps of each fracturing operation sub-area are generated, specifically including:

[0020] According to the discharge volume of fracturing flowback fluid at each fracturing operation point at each moment, the total discharge volume of fracturing flowback fluid at each fracturing operation sub-area at each moment is calculated;

[0021] The total amount of the fracturing flowback fluid discharged at each moment is used as the fracturing flowback fluid processing task of the fracturing flowback fluid reuse pool corresponding to each fracturing operation sub-area.

[0022] Optionally, the state information of the fracturing flowback fluid reuse pool network is obtained, and the fracturing flowback fluid processing control instruction step is generated according to the state information and the fracturing flowback fluid processing task, specifically including:

[0060] The specific embodiments of the present invention applied to the device are basically the same as the embodiments of the following oil and gas field fracturing flowback fluid treatment control method, and will not be described in detail here.

[0061] The embodiment of the present invention provides a method for controlling the treatment of oil and gas field fracturing flowback fluid, referring to Figure 2 , Figure 2 The present invention is a schematic flow chart of an embodiment of a method for controlling the treatment of oil and gas field fracturing flowback fluid.

[0062] In this embodiment, the oil and gas field fracturing flowback fluid processing control method includes the following steps:

[0063] S100: Acquire a fracturing operation task table of a target operation area; wherein the target operation area includes a plurality of fracturing operation sub-areas, each of the fracturing operation sub-areas has a plurality of fracturing operation points, and the fracturing operation task table includes a fracturing operation task of each fracturing operation point in a target period;

[0067] S500: Sending the fracturing flowback fluid processing control instruction to the fracturing flowback fluid buffer scheduling device and the fracturing flowback fluid processing device, respectively executing the fracturing flowback fluid scheduling action and the fracturing flowback fluid processing action to complete the fracturing flowback fluid processing in the target operation area.

[0068] It should be noted that, at present, the main problem with the treatment of fracturing return fluid is the insufficient number of fracturing return fluid treatment equipment (cost and site limitations). Therefore, in actual engineering applications, a treatment method is usually adopted in which several fracturing operation points use a group of fracturing return fluid treatment equipment. Although this solves the problem of insufficient quantity very well, it also leads to the need for coordination of fracturing return fluid treatment tasks with very high accuracy among multiple fracturing operation points. Otherwise, it will affect the fracturing operation tasks of multiple fracturing operation points and affect the production progress of the enterprise. In order to solve the above problems, this embodiment obtains the fracturing operation tasks of each fracturing operation point in each fracturing operation sub-area, generates the fracturing return fluid processing tasks of each fracturing operation sub-area, and then adjusts the fracturing return fluid processing speed of each fracturing operation sub-area and the calls between different fracturing return fluid reuse pools by considering the state of the fracturing return fluid reuse pool network. In this way, it is ensured that each fracturing return fluid reuse pool is always within the range of the maximum buffer capacity, thereby ensuring that the fracturing operation point can continuously discharge and process the fracturing return fluid, and the fracturing operation tasks of multiple fracturing operation points can be executed on time, thereby improving the efficiency of fracturing return fluid treatment, reducing the energy consumed in the treatment process, and maximizing corporate benefits.

[0069] In a preferred embodiment, the step of obtaining the fracturing operation task table of the target operation area specifically includes: accessing the fracturing operation task database to extract the fracturing operation tasks that are assigned to each fracturing operation point and need to be performed within the target time period; calling the comparison relationship table between the fracturing operation point and the fracturing return fluid reuse pool to obtain the fracturing return fluid reuse pool corresponding to each fracturing operation point, and treating several fracturing operation points using the same fracturing return fluid reuse pool as fracturing operation points in the same fracturing operation sub-area.

[0070] In this embodiment, by accessing the fracturing operation task database, the fracturing operation tasks of each fracturing operation point in the target time period that are pre-formulated and issued are queried, and according to the relationship between the fracturing operation point and the fracturing return fluid reuse pool, several fracturing operation points using the same fracturing return fluid reuse pool are regarded as fracturing operation points of the same fracturing operation sub-area, and finally several fracturing operation sub-areas are obtained, thereby controlling and coordinating the fracturing return fluid treatment for each fracturing operation sub-area.

[0071] In a preferred embodiment, based on the fracturing operation task, the steps of determining the fracturing return fluid processing information of each fracturing operation point specifically include: extracting the fracturing operation parameters in the fracturing operation task; wherein the fracturing operation parameters include the fracturing operation time and the fracturing fluid usage; querying the fracturing return rate corresponding to each fracturing operation point in the current operation stage, and generating the fracturing return fluid discharge volume of each fracturing operation point at each moment in the target time period according to the fracturing operation time, the fracturing fluid usage and the fracturing return rate; generating the fracturing return fluid processing information of each fracturing operation point according to the timestamp information at each moment and the corresponding fracturing return fluid discharge volume.

[0072] In this embodiment, the fracturing operation parameters include the fracturing operation time and the amount of fracturing fluid used. Then, according to the fracturing flowback rate of the current operation stage, the discharge amount of the fracturing flowback fluid at each fracturing operation point at each moment can be calculated.

[0073] In a preferred embodiment, based on the fracturing flowback fluid processing information of each fracturing operation point, the fracturing flowback fluid processing task steps for each fracturing operation sub-area are generated, specifically including: calculating the total amount of fracturing flowback fluid discharged from each fracturing operation sub-area at each moment according to the fracturing flowback fluid discharge volume of each fracturing operation point at each moment; and using the total amount of fracturing flowback fluid discharged at each moment as the fracturing flowback fluid processing task of the fracturing flowback fluid reuse pool corresponding to each fracturing operation sub-area.

[0074] In this embodiment, the discharge volumes of fracturing flowback fluid from several fracturing operation points in a fracturing operation sub-area are summed up to obtain the total discharge volume of fracturing flowback fluid in each fracturing operation sub-area at each moment, thereby controlling and coordinating the fracturing flowback fluid treatment for each fracturing operation sub-area.

[0075] In a preferred embodiment, the status information of the fracturing return fluid reuse pool network is obtained, and the steps of generating a fracturing return fluid processing control instruction are generated according to the status information and the fracturing return fluid processing task, which specifically include: obtaining the status information of the fracturing return fluid reuse pool network; wherein the fracturing return fluid reuse pool network includes a plurality of fracturing return fluid reuse pools corresponding to each fracturing operation sub-area respectively, and the status information includes the connection relationship between any two fracturing return fluid reuse pools and the fracturing return fluid buffer volume of each fracturing return fluid reuse pool; extracting the total amount of fracturing return fluid discharged from each fracturing operation sub-area at each moment in the fracturing return fluid processing task, and generating a fracturing return fluid processing control instruction according to the relationship between the sum of the total amount of fracturing return fluid discharged and the fracturing return fluid buffer volume and the buffer volume upper limit of each fracturing return fluid reuse pool; wherein the fracturing return fluid processing control instruction includes a fracturing return fluid buffer scheduling instruction and a fracturing return fluid processing instruction.

[0076] In this embodiment, the status information of the fracturing return fluid reuse pool network includes the connection relationship between any two fracturing return fluid reuse pools (for example, reuse pool A is connected with reuse pools B, C, and D and can schedule fracturing return fluid with each other) and the fracturing return fluid buffer capacity of each fracturing return fluid reuse pool (that is, the fracturing return fluid buffer capacity of each fracturing return fluid reuse pool at the beginning of the target time period). Therefore, according to the connection relationship and the fracturing return fluid buffer capacity, fracturing return fluid buffer scheduling instructions and fracturing return fluid processing instructions can be generated to achieve the adjustment of the fracturing return fluid processing speed and scheduling of each fracturing return fluid reuse pool, thereby ensuring that each fracturing return fluid reuse pool is below the buffer capacity upper limit and does not affect the execution of fracturing operation tasks by the fracturing operation point connected to the fracturing return fluid reuse pool.

[0077] In a preferred embodiment, according to the relationship between the total amount of fracturing return fluid discharged, the sum of the fracturing return fluid buffer volume and the buffer volume upper limit of each fracturing return fluid reuse pool, a fracturing return fluid processing control instruction step is generated, which specifically includes: according to the relationship between the total amount of fracturing return fluid discharged, the sum of the fracturing return fluid buffer volume and the buffer volume upper limit of each fracturing return fluid reuse pool at each moment, adjusting the fracturing return fluid processing speed of the fracturing return fluid processing equipment corresponding to each moment; based on the fracturing return fluid processing speed, generating a fracturing return fluid processing control instruction for controlling the processing speed of the fracturing return fluid processing equipment; wherein, the fracturing return fluid processing control instruction includes a first control instruction for controlling a solid-liquid separation equipment and a second control instruction for controlling an aeration equipment; wherein, the first control instruction is configured to control the access usage ratio of a filtration equipment and a filter press equipment, and the second control instruction is configured to control the pump gas power level of an aeration equipment.

[0078] In this embodiment, the adjustment of the fracturing return fluid processing speed of each fracturing return fluid reuse pool is mainly achieved by controlling the equipment that can significantly reduce the processing time (such as filtering equipment and aeration equipment, etc., using different equipment access and different equipment power) to control the overall processing speed of the fracturing return fluid, and finally the most appropriate fracturing return fluid processing control instructions are determined based on the fracturing return fluid processing speed that meets each fracturing operation sub-area.

[0079] In a preferred embodiment, according to the relationship between the sum of the total discharge amount of the fracturing return fluid and the fracturing return fluid buffer amount at each moment and the buffer amount upper limit of each fracturing return fluid reuse pool, the step of adjusting the fracturing return fluid processing speed of the fracturing return fluid processing equipment corresponding to each moment specifically includes: judging whether there is a fracturing return fluid buffer amount obtained by subtracting the sum of the fracturing return fluid standard processing speeds at each moment before the target moment from the sum of the total discharge amount of the fracturing return fluid and the fracturing return fluid buffer amount calculated at the target moment, which exceeds the buffer amount upper limit; if so, adjusting the fracturing return fluid processing control instruction so that the sum of the power at each moment in the target time period is greater than that before the adjustment, and re-executing the above-mentioned judging step until There is no fracturing return fluid buffer volume at the target moment that exceeds the buffer volume upper limit, and the fracturing return fluid standard processing speed corresponding to the current fracturing return fluid processing control instruction is used as the fracturing return fluid processing speed of the fracturing return fluid processing equipment in the final target time period; if the sum of the powers at each moment in the target time period has been adjusted to the maximum, and there is still a fracturing return fluid buffer volume at the target moment that exceeds the buffer volume upper limit, then according to the connection relationship between the fracturing return fluid reuse pools, a third control instruction for controlling the fracturing return fluid buffer scheduling device is generated; according to the third control instruction, the fracturing return fluid buffer volume of the target fracturing return fluid reuse pool is dispatched to the adjacent fracturing return fluid reuse pool, and the above-mentioned judgment process is re-executed in the target fracturing return fluid reuse pool and the adjacent fracturing return fluid reuse pool until there is no situation in which the fracturing return fluid buffer volume at the target moment exceeds the buffer volume upper limit in each fracturing return fluid reuse pool.

[0080] In this embodiment, the method of adjusting the processing speed of the fracturing return fluid is: first, the fracturing return fluid processing equipment is controlled at the lowest power to judge whether the processing speed satisfies the requirement that the buffer amount does not exceed the upper limit of the buffer amount at each moment; if it cannot be satisfied, the power is gradually increased until the fracturing return fluid processing speed with the buffer amount not exceeding the upper limit of the buffer amount and the lowest power is found, and then the corresponding first control instruction and second control instruction are generated. It should be noted that if the power is still not met when it is increased to the maximum, it is necessary to generate a third control instruction to control the fracturing return fluid cache scheduling equipment, and schedule the fracturing return fluid cache volume of the target fracturing return fluid reuse pool to the adjacent fracturing return fluid reuse pool, and then re-judgment the cache volume upper limit judgment process of the target fracturing return fluid reuse pool and the adjacent fracturing return fluid reuse pool, and finally, achieve the purpose of ensuring that each fracturing return fluid reuse pool is below the cache volume upper limit, and thereby generate the final first control instruction, second control instruction and third control instruction, to achieve the coordinated execution of the fracturing return fluid processing tasks corresponding to each fracturing operation sub-area, without affecting the execution of fracturing operation tasks by the fracturing operation point connected to the fracturing return fluid reuse pool.

[0081] In this embodiment, a method for controlling the processing of fracturing return fluid in an oil and gas field is provided. The method generates a fracturing return fluid processing task for each fracturing operation sub-area by acquiring the fracturing operation task of each fracturing operation point in each fracturing operation sub-area, and then adjusts the fracturing return fluid processing speed of each fracturing operation sub-area and the calls between different fracturing return fluid reuse pools by considering the state of the fracturing return fluid reuse pool network. In this way, it is ensured that each fracturing return fluid reuse pool is always within the range of the maximum buffer capacity, thereby ensuring that the fracturing operation point can continuously discharge and process the fracturing return fluid, and the fracturing operation tasks of multiple fracturing operation points can be executed on time, thereby improving the efficiency of fracturing return fluid processing, reducing the energy consumed in the processing process, and maximizing corporate benefits.
