Description

Technical Field

[0001] The invention belongs to the technical field of oil and gas exploration, and in particular relates to a multi-channel parallel booster type temporary plugging material adding device and a process method. Background Art

[0002] Temporary plugging fracturing can achieve the diversity and complexity of reservoir fractures, improve reservoir permeability, and increase production effects. It is widely used in the production enhancement and transformation operations of oil and gas reservoirs. There are three main ways to add temporary plugging materials: the first is to add them manually through the mixing tank of the sand mixer, which is mainly suitable for granular temporary plugging agents. The addition speed depends on experience, the labor intensity is high, the operation requirements are high, and there are safety hazards such as high-pressure damage and falling from heights. It is easy to cause the pump head of the fracturing truck to stick and suffocate, causing the risk of construction interruption; the second is to connect the side branch of the storage pipe pre-loaded with temporary plugging materials to the high-pressure manifold at the rear end of the pump truck, which is mainly suitable for temporary plugging balls. When filling is required, the valve of the side branch manifold is manually opened. This method has the risk of high-pressure damage, the total amount added is small, and the addition speed and concentration are uncontrollable; the third is to run a special temporary plugging material pumping system in the high-pressure manifold. The characteristics are that the temporary plugging material pumping system equipment is large and the cost is high, which is not suitable for low-cost development strategies.

[0003] The Chinese patent document with publication number CN112878976 A discloses a remote-controlled temporary plugging material injection system and application method. The remote-controlled temporary plugging material injection device includes a temporary plugging agent injection system, a temporary plugging agent storage system and a pressure isolation system, which is mainly used to inject temporary plugging agents and temporary plugging balls into the high-pressure manifold to prevent the temporary plugging agent from being unable to enter the manifold smoothly due to insufficient gravity to overcome resistance. The device in the document adopts remote control operation, relying on electric-controlled hydraulic power to control the temporary plugging agent injection system and the switch pressure isolation system, so as to avoid construction personnel from crossing the high-pressure area to ensure the safety of on-site construction personnel, so as to avoid possible high-pressure leakage injuries. It realizes the temporary plugging agent and temporary plugging ball that are continuously pumped into the high-pressure manifold, greatly improving the continuity of temporary plugging fracturing operation; shortening the construction time and reducing the construction cost; however, the device in the document still has a special temporary plugging material pumping system in the high-pressure manifold, which is characterized by large equipment and high cost of the temporary plugging material pumping system, which is not suitable for low-cost development strategy; at the same time, when the temporary plugging material is pushed from the temporary plugging material storage chamber into the high-pressure manifold by the push rod, firstly, the temporary plugging material cannot be pushed in when the push rod is stretched, which prolongs the injection time; secondly, the temporary plugging material exists in the storage chamber, and is limited by the storage chamber space, and cannot meet the injection of large-capacity temporary plugging materials; since the device in the document is a high-pressure device, a pressure sealing system needs to be set up, which has a complex structure and high cost.

[0004] Aiming at the high labor intensity and high experience requirement of low-pressure adding in sand mixing truck, the problems of high-pressure injury, falling from height, pump head sticking, pump blocking, as well as the high-pressure injury of temporary plugging material pre-placed in the side branch pipe of the high-pressure manifold, small adding amount, uncontrollable adding speed and concentration, a multi-channel parallel booster temporary plugging material adding device and process method are proposed to realize remote control of automatic addition of large-capacity high-pressure end of multiple types of temporary plugging materials.

[0035] Embodiment 1:

[0036] like Figure 1 and Figure 2As shown, a multi-channel parallel booster temporary plugging material addition device includes an input pipeline 1, an output pipeline 2, multiple injection pipelines 3 and multiple addition units, the left side of the input pipeline 1 is respectively connected to multiple valves 1 4, the right side of the input pipeline 1 is respectively connected to the inlets of the multiple injection pipelines 3, the outlets of the multiple injection pipelines 3 are all connected to the left side of the output pipeline 2, the right side of the output pipeline 2 is respectively connected to multiple valves 2 5, and each injection pipeline 3 is connected to one addition unit.

[0037] Specifically, the input pipeline 1, the output pipeline 2 and the multiple injection pipelines 3 are all arranged horizontally, and the multiple adding units are all arranged vertically. The number of valves 1 4, valves 2 5 and adding units is selected according to the actual situation to meet the needs; preferably, the number of valves 1 4 and valves 2 5 is 6 specifications, and the number of adding units is 3. The structure is simple, the operation is convenient, the space is small, and the cost is reduced while the use requirements are maximized. Multiple high-pressure fracturing pipelines can be connected to the multi-channel parallel booster temporary plugging material adding device at the same time, ensuring the addition concentration, addition speed and uniformity of the temporary plugging material addition. Up to 6 fracturing pipelines can be connected to meet the maximum number of current fracturing pipelines. Multiple adding units are connected in parallel through the input pipeline 1, the output pipeline 2 and the multiple injection pipelines 3, and each selective switch can adjust the addition concentration of the temporary plugging material at any time to optimize the construction parameters of the temporary plugging material for temporary plugging fracturing. The temporary plugging material is added through multiple adding unit side branches, which can significantly increase the addition concentration compared with the addition of the sand mixing truck, and reduce the risk of temporary plugging material blockage compared with the straight-through addition. It solves the contradiction between large volume and low pressure bearing, overcomes the shortcoming of small volume of existing high-pressure adding device, and realizes the goal of large-capacity adding of temporary plugging materials.

[0038] Embodiment 2:

[0039] Based on Example 1, each adding unit includes a funnel 6, a storage bin 7, a valve three 8 and a valve four 9, and the funnel 6, the valve three 8, the storage bin 7, the valve four 9 and the injection pipeline 3 are connected in sequence from top to bottom.

[0040] The addition of material into the storage bin 7 is controlled by the valve three 8, and the discharge of material from the storage bin 7 is controlled by the valve four 9. The structure is simple and the operation is convenient.

[0041] Specifically, the funnel 6 is a trumpet-shaped thin-walled pipe fitting with a larger upper end and a smaller lower end. The lower end of the funnel 6 is connected to the valve 3 8 through a union.

[0042] The upper part of the storage bin 7 is cylindrical, and the lower part is a cone-shaped funnel. A cover plate is provided at the upper end of the cylinder, and a hole is provided in the center of the cover plate. The upper end of the storage bin 7 is connected to valve 3 8 through a union; the lower part of the cone barrel has a hole, and the lower end of the storage bin 7 is connected to valve 4 9 through a union.

[0043] Preferably, each of the adding units further comprises a displacement pipe 10 , one end of the displacement pipe 10 is connected to the injection pipeline 3 , and the other end of the displacement pipe 10 is connected to the upper side of the storage bin 7 .

[0044] Specifically, a through hole is opened on the upper side of the storage bin 7, and the displacement pipe 10 is welded or threadedly connected to the through hole; the storage bin 7 is replenished and displaced through the displacement pipe 10 to prevent the liquid at the lower end of the storage bin 7 from flowing back, thereby solving the problem that the upper part of the storage bin 7 is empty due to the falling of the temporary plugging material, forcing the liquid below to return, causing the temporary plugging material to float and swirl, resulting in the continuous attenuation of the concentration of the temporary plugging material, delaying the addition time of the temporary plugging material, and affecting the temporary plugging effect.

[0045] Specifically, the input pipeline 1, the output pipeline 2, the plurality of injection pipelines 3 and the displacement pipe 10 are all circular tubular structures, and both ends of the circular tubes are union joints, which are convenient for material collection and connection.

[0046] The input pipeline 1 and the plurality of injection pipelines 3 , the plurality of injection pipelines 3 and the output pipeline 2 , and the displacement pipe 10 and the injection pipeline 3 are all connected via T-type unions.

[0047] Preferably, the displacement pipe 10 is connected to a regulator 11 .

[0048] Specifically, the regulator 11 is a straight pipe thread structure; due to the dimensional errors of the components, the vertical installation dimensions of the joining unit cannot be accurately controlled, and the regulator 11 can be used to adjust the vertical installation position of the joining unit.

[0049] Preferably, each of the adding units further comprises a rectifier 12, and the rectifier 12 is connected to the injection pipeline 3 between the displacement pipe 10 and the valve 29.

[0050] The rectifier 12 is a straight pipe threaded throttle structure. The thread is used to adjust the horizontal assembly position of the displacement pipe 10. The throttle can form an upstream and downstream pressure difference, forcing more fracturing fluid to flow through the displacement pipe, thereby boosting the speed of adding temporary plugging materials.

[0051] Preferably, the upper end of the displacement pipe 10 is connected to a drain valve 13 .

[0052] The air in the storage bin is discharged through the exhaust valve 13 to ensure smoothness of adding temporary plugging material into the storage bin through the funnel 6.

[0053] Preferably, a rotor 14 is provided in the storage bin 7 .

[0054] The fracturing fluid in the displacement pipe 10 drives the rotor 14 in the storage bin 7 to rotate, and the spiral 143 at the lower end of the rotor can ensure the smooth and sequential addition of temporary plugging materials to prevent the temporary plugging agent particles in the storage bin 7 from agglomerating or bridging.

[0055] Preferably, the rotor 14 includes a core shaft 141 , an impeller 142 and a screw 143 , wherein the upper end of the core shaft 141 is connected to the impeller 142 , and the lower end of the core shaft 141 is connected to the screw 143 .

[0056] Since the temporary plugging balls have a large outer diameter, they can easily form bridges when freely piled up at the outlet of the storage bin, and the spiral can ensure the smooth and sequential delivery of the temporary plugging balls. Therefore, the device can be used to add temporary plugging balls or granular temporary plugging agents, and is a device that is compatible with adding multiple temporary plugging materials. The rotor structure of this structure is simple, easy to operate, and has a good rotation effect.

[0057] Preferably, the horizontal pipe at the upper portion of the displacement pipe 10 is connected to the upper side section of the storage bin 7 .

[0058] It is ensured that the water flow coming out of the displacement pipe 10 can better drive the rotation of the impeller 142.

[0059] Preferably, the valve four 9 is a remote control valve.

[0060] The valve 4 9 is a remote control valve, which realizes the remote control of the automatic addition of temporary plugging materials, avoids the risk of high pressure injury caused by direct addition of existing high pressure manifolds, is easy to operate, efficient and fast, and reduces the labor intensity of personnel. The remote control valve of the present invention has a large caliber, which avoids the blockage of temporary plugging balls caused by three-ball bridging, and thus also meets the needs of sequential addition of temporary plugging balls with larger diameters.

[0061] Preferably, the remote control valve is an electrically controlled hydraulic plug valve.

[0062] The electric-controlled hydraulic plug valve is used to remotely control the on-off of the pipeline flow channel. It opens and closes quickly, is light, has a large torque, a simple and compact structure, is relatively small in size, light in weight, easy to maintain, and has good sealing performance.

[0063] Preferably, the valve 2 5 and the valve 3 8 are both plug valves. The plug valve is a kind of ball valve with a compact structure and quick action, and is used to control the on-off of the pipeline flow channel.

[0064] Preferably, the valve 1 4 is a one-way valve to ensure that the fracturing fluid flows along the construction direction and avoids backflow.

[0065] Embodiment 3:

[0066] Based on Example 2, a process method for adding a multi-channel parallel booster temporary plugging material device includes the following steps:

[0067] 1) The input pipeline 1 is connected to the upstream of multiple fracturing pipelines through multiple valves 1 4, and the output pipeline 2 is connected to the downstream of multiple fracturing pipelines through multiple valves 2 5;

[0068] The high-pressure manifold for large-scale fracturing generally has multiple fracturing pipelines connected to the wellhead. Multiple valves 1-4 (one-way valves) of the input pipeline 1 of the device are connected to the upstream of the multiple fracturing pipelines through a union, and multiple valves 2-5 of the output pipeline of the device are connected to the downstream of the multiple fracturing pipelines through a union. Up to 6 fracturing pipelines can be connected. Idle valves 1-4 do not need to be managed, and idle valves 2-5 need to be closed.

[0069] 2) Open the valve three 8 and the drain valve 13 in the multiple adding units, close the valve four 9 in the multiple adding units, add the target amount of temporary plugging material into the storage bin 7 through the funnel 6, and the air in the storage bin 7 replaced by the temporary plugging material is discharged through the drain valve 13;

[0070] 3) Close the valves 3 8 and the drain valve 13 in the multiple adding units, open the valve 2 connected to the fracturing pipeline, close the remaining valves 2, and perform fracturing construction;

[0071] 4) When temporary plugging material needs to be added, the corresponding number of valves 49 are opened according to the concentration of the temporary plugging material (the more valves 4 are opened, the greater the concentration and the faster the adding speed), and the temporary plugging material falls to the injection pipeline 3 through the valve 49, and the falling temporary plugging material is carried by the fracturing fluid and injected into the wellbore. At the same time, the fracturing fluid is replenished into the storage bin 7 through the displacement pipe 10. The fracturing fluid in the displacement pipe 10 impacts the impeller 141 at the upper end of the rotor 14 in the storage bin 7 to rotate, driving the spiral 143 at the lower end of the rotor to rotate, and pushing the temporary plugging material to fall steadily. The function of the rectifier is to form a sufficient pressure difference between the upper and lower storage bins, forcing more fracturing fluid to flow through the displacement pipe, and boosting the adding speed of the temporary plugging material.

[0072] Until the feeding is completed, close the valve 9 and continue the fracturing operation to prevent the sand-carrying fluid from flowing through the storage bin and causing wear of the rotor 14 in the storage bin 7.

[0073] 5) After the construction is completed, the fracturing pipelines connected to valve 1 4 and valve 2 5 are dismantled.

[0074] The present invention achieves the goal of adding temporary plugging materials to high-pressure pipelines through remote control, and avoids the problems of high labor intensity, high-pressure injuries, falling from heights, pump head sticking, and pump blockage caused by adding materials by sand mixing trucks. The multi-channel parallel structure of small-volume storage bins solves the contradiction between large volume and low pressure bearing, overcomes the shortcomings of small volume of existing high-pressure adding devices, and achieves the goal of adding temporary plugging materials in large quantities. Selective opening of multiple adding units can adjust the addition concentration and addition speed of temporary plugging materials. By adopting the side branch addition of temporary plugging materials, the addition concentration can be significantly increased compared with the addition of sand mixing trucks, and the risk of temporary plugging material blockage can be reduced compared with the straight-through addition. The displacement pipe can not only promote the rapid addition of temporary plugging materials, but also drive the rotor in the storage bin to ensure the smooth and sequential addition of temporary plugging materials. The full addition of the fracturing pipeline not only meets the large-displacement fracturing construction, but also ensures the concentration of temporary plugging materials and the uniformity of temporary plugging materials in the fracturing fluid. Since the temporary blocking balls have a large outer diameter, they can easily form bridges when freely stacked at the storage bin outlet. The spiral can ensure the smooth and sequential transportation of the temporary blocking balls. Therefore, the device can be used to add both temporary blocking balls and granular temporary blocking agents. It is a device that is compatible with adding multiple temporary blocking materials.
