Description

Technical Field

[0001] The present invention relates to the technical field of deep - sea oil production, and specifically to an intelligent oil production device. Background Art

[0002] Oil wells in offshore oilfields are usually located on the seabed hundreds to thousands of meters deep, and the operating environment is complex. In the completion section of the oil well, perforators are often used as tools for drilling holes between the oil layer and the wellbore. By perforating the completion section of the oil well, the oil and gas layer is connected to the wellbore to ensure that oil and gas can flow smoothly into the wellbore through these holes and finally be pumped to the ground. The perforator consists of a perforator body and perforating charges. The perforating charge device is located inside the perforator body. After activation, the perforating charges will generate a powerful jet flow. Through the impact force generated by high - energy explosion, it penetrates the rock of the wellbore wall and the oil and gas layer, thus drilling holes in the wellbore wall and forming channels. In this way, oil and gas can flow smoothly into the wellbore to start subsequent collection operations. Since the perforating charge mounting holes on the perforator are fixedly distributed on the surface of the perforator, when loading the perforating charges, it is necessary to frequently rotate the perforator to ensure that each perforating charge can be correctly placed into the corresponding mounting hole. This operation process is not only cumbersome but also has a low loading efficiency. Especially in a complex environment such as an offshore oilfield, it depends on professional offshore drilling platforms or other offshore equipment, and the scheduling, use, and maintenance costs of these equipment are very high. This makes multiple links and operations usually carried out simultaneously in offshore oilfields, and the delay of perforating operations will affect other subsequent operation plans, not only increasing the operation cost but also affecting the efficiency of oil and gas extraction.

[0016] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] As shown in Figures 1 to 7 the figure, an intelligent oil production device according to the present invention includes a perforator and a perforating charge 11 installed on the perforator; the perforator is composed of a cartridge holder 1 and a casing 12; spiral distribution mounting holes 121 are formed on the surface of the casing 12; the perforating charge 11 is installed in the mounting holes 121; the cartridge holder 1 is inserted into the casing 12; the cartridge holder 1 includes a plurality of U-shaped frames 13 and a top plate 14; adjacent two U-shaped frames 13 are rotatably connected; the top plate 14 is rotatably connected to the upper end of the U-shaped frame 13 located above; the lower end of the U-shaped frame 13 located at the bottom is rotatably connected to a threaded cover 131 threadedly connected to the casing 12; a circular groove 141 is formed at the upper end of the top plate 14; a push rod 142 is slidably connected in the circular groove 141; the push rod 142 is connected to the groove wall of the circular groove 141 through a push spring 143; an arc-shaped groove 144 communicating with the circular groove 141 is formed on the side wall of the top plate 14; an arc-shaped block 145 is slidably and sealingly connected in the arc-shaped groove 144; a positioning hole 122 matching with the push rod 142 is formed at the top end of the casing 12; A positioning unit, the positioning unit is installed inside the U-shaped frame 13; the positioning unit is used to fix adjacent U-shaped frames 13.

[0018] As an embodiment of the present invention, the positioning unit includes a positioning rod 133; grooves 15 are formed at the lower ends of both the U-shaped frame 13 and the top plate 14; a slot 151 is formed at the bottom of the groove 15; a positioning groove 132 is formed at the upper end of the U-shaped frame 13; the positioning rod 133 is slidably connected in the positioning groove 132; the positioning rod 133 is connected to the bottom of the positioning groove 132 through a positioning spring 134; a fixing groove 135 is also formed at the bottom of the groove 15.

[0019] As an embodiment of the present invention, a sealing groove 16 is formed at the bottom of the slot 151; a sealing rod 161 is slidably connected inside the sealing groove 16; the sealing rod 161 located inside the top plate 14 is fixedly connected to the push rod 142; the sealing rod 161 located inside the U-shaped frame 13 is connected to the positioning rod 133 through a steel wire rope 162.

[0020] As an embodiment of the present invention, the depth of the fixing groove 135 is greater than the depth of the slot 151.

[0021] As an embodiment of the present invention, a straight groove 146 is formed on the surface of the arc-shaped block 145; the arc-shaped block 145, the push rod 142 and the positioning rod 133 are all made of fluororubber material.

[0022] During operation, the perforating charge mounting holes 121 on the perforator are fixedly distributed on the surface of the perforator. When loading the perforating charges 11, it is necessary to frequently rotate the perforator to ensure that each perforating charge 11 can be correctly placed into the corresponding mounting hole 121. This operation process is not only cumbersome but also has a low loading efficiency. Especially in a complex environment such as an offshore oilfield, it depends on professional offshore drilling platforms or other offshore equipment, and the scheduling, use, and maintenance costs of these equipment are very high. This makes multiple links and operations usually carried out simultaneously in an offshore oilfield, and the delay of the perforating operation will affect other subsequent operation plans, not only increasing the operation cost but also affecting the efficiency of oil and gas production.

[0023] In view of this, the present invention simplifies the loading process and improves the loading efficiency of the perforating charges 11 by setting up a cartridge rack 1, enabling the perforating charges 11 to be directly inserted into the cartridge rack 1, then inserting the cartridge rack 1 loaded with the perforating charges 11 into the sleeve, connecting the cartridge rack 1 with the sleeve, and rotating the cartridge rack 1 to drive the perforating charges 11 to rotate, so that the perforating charges 11 are aligned with the mounting holes 121 of the casing 12, thus eliminating the need to frequently rotate the perforator to install the perforating charges 11. Furthermore, it ensures that the perforating operation is completed on time, avoiding affecting subsequent operation plans, not only reducing the operation cost but also improving the efficiency of oil and gas production.

[0024] In the initial state, the number of U-shaped frames 13 of the cartridge rack 1 is the same as the number of mounting holes 121 on the surface of the casing 12. The positioning rods 133 at the upper ends of the U-shaped frames 13 located below are inserted into the slots 151 at the lower ends of the U-shaped frames 13 above. At this time, multiple U-shaped frames 13 are vertically arranged and inserted into each other. In addition, the U-shaped openings of multiple U-shaped frames 13 are in the same plane. The user first inserts multiple perforating charges 11 into the U-shaped openings of the U-shaped frames 13. Since multiple U-shaped frames 13 are vertically arranged and the U-shaped openings are in the same plane, there is no need to rotate the cartridge rack 1 during the insertion of the perforating charges 11, simplifying the loading process of the perforating charges 11 and improving the loading efficiency of the perforating charges 11 and the installation speed of the leads and the perforating charges 11. Subsequently, the cartridge rack 1 loaded with the perforating charges 11 is inserted into the casing 12 from the port of the casing 12.

[0025] When the ammunition rack 1 is inserted into the sleeve 12, the top plate 14 at the upper end of the ammunition rack 1 continuously approaches the top end of the sleeve 12, so that the top plate 14 can drive the push rod 142 at the upper end to approach the top end of the sleeve 12. When the push rod 142 contacts the top end of the sleeve 12, the ammunition rack 1 is continuously pushed into the push rod, so that the push rod 142 blocked by the top end of the sleeve 12 can squeeze the push spring 143 into the circular groove 141. Then the ammunition rack 1 is rotated, so that the ammunition rack 1 can drive the push rod 142 to rotate through the top plate 14. When the push rod 142 rotates to the positioning hole 122, the push rod 142 is pushed by the push spring 143 and enters the positioning hole 122, so that the push rod 142 inserted into the positioning hole 122 connects the top plate 14 and the sleeve 12. Then the ammunition rack 1 is continuously pushed into the sleeve 12, so that the push rod 142 in the positioning hole 122 is blocked by the bottom end of the positioning hole 122 and continues to squeeze the push spring 143 into the circular groove 141. Since the circular groove 141 is filled with hydraulic oil, the hydraulic oil in the circular groove 141 is squeezed into the arc-shaped groove 144 communicated with the circular groove 141, so that the arc-shaped block 145 in the arc-shaped groove 144 is pushed by the hydraulic oil and extends out of the arc-shaped groove 144 until the arc-shaped block 145 extending out of the arc-shaped groove 144 contacts the inner wall of the sleeve 12, so that the arc-shaped block 145 is pushed by the hydraulic oil and abuts against the inner wall of the sleeve 12. Since the straight groove 146 is arranged on the surface of the arc-shaped block 145, the arrangement of the straight groove 146 can increase the surface roughness of the arc-shaped block 145, thereby increasing the friction force between the arc-shaped block 145 and the inner wall of the sleeve 12, so that the top plate 14 is fixed in the sleeve.

[0026] Since the sealing rod 161 inside the top plate 14 is fixedly connected to the push rod 142, during the process of the push rod 142 squeezing the push spring 143 into the circular groove 141, the push rod 142 will push the sealing rod 161 connected to it to extend out of the sealing groove 16, so that the sealing rod 161 enters the slot 151. Because the positioning rod 133 at the upper end of the uppermost U-shaped frame 13 is inserted into the slot 151 at the lower end of the top plate 14, the sealing rod 161 entering the slot 151 will push the positioning rod 133 to squeeze the positioning spring 134 into the positioning groove 132 until the sealing rod 161 completely enters the slot 151, so that the positioning rod 133 extends out of the slot 151 and is located in the groove 15. Because the shape of the groove 15 is annular, the lowermost U-shaped frame 13 is rotated, so that the lowermost U-shaped frame 13 can drive a plurality of sequentially inserted U-shaped frames 13 at the upper end to rotate synchronously. At this time, the uppermost U-shaped frame 13 drives the positioning rod 133 to rotate in the groove 15. At this time, until the U-shaped frame 13 drives the positioning rod 133 to rotate 90° to the fixing groove 135, at this time, the perforating bullet 11 in the uppermost U-shaped frame 13 is aligned with the mounting hole 121 near the top end of the sleeve 12, and the positioning rod 133 is pushed by the positioning spring 134 and enters the fixing groove 135.

[0027] Since the depth of the fixing groove 135 is greater than that of the slot 151, and in the initial state, the positioning spring 134 is always in a compressed state. Therefore, during the process of inserting the positioning rod 133 into the fixing groove 135, the positioning rod 133 will pull the wire rope 162 fixedly connected thereto to rise, causing the wire rope 162 to pull the sealing rod 161 connected to the other end to descend, so that the sealing rod 161 in the U-shaped frame 13 extends out of the sealing groove 16 and inserts into the slot 151, and the sealing rod 161 in the U-shaped frame 13 pushes the positioning rod 133 in the lower U-shaped frame 13 into the annular groove 111. At this time, the uppermost U-shaped frame 13 is rotatably connected to the U-shaped frame 13 below it, and the uppermost U-shaped frame 13 is inserted into the top plate 14. Rotate the lowermost U-shaped frame 13, so that the uppermost U-shaped frame 13 rotates relative to the connection group of the U-shaped frame 13 connected below it, causing the second U-shaped frame 13 from the top to drive the positioning rod 133 to rotate 90° to the fixing groove 135 of the uppermost U-shaped frame 13. At this time, the perforating charge 11 of the second U-shaped frame 13 from the top is aligned with the mounting hole 121 of the casing 12. Repeat this process until all the perforating charges 11 on the mounting frames are aligned with the mounting holes 121 of the casing 12, thus completing the alignment of the perforating charges 11 and the mounting holes 121 of the casing 12. Subsequently, control the positioning unit to push the perforating charge 11 into the mounting hole 121 of the casing 12, and then rotate the threaded cap 131 so that the threaded cap 131 is threadedly connected to the casing 12. The bullet rack 1 is blocked by the threaded cap 131 and fixed in the casing 12. At this time, the installation of the perforator is completed.

[0028] For the recovery of the used bullet rack 1, it is necessary to first use a tool to pull out the bullet rack 1 from the casing 12. Since the positioning rod 133 of the lower U-shaped frame 13 is inserted into the fixing groove 135 of the upper U-shaped frame 13, the slot 151 of the upper U-shaped frame 13 is in an exposed state. By using a tool such as a screwdriver and inserting it into the slot 151, the screwdriver inserted into the slot 151 pushes the sealing rod 161 into the sealing groove 16, causing the sealing rod 161 to pull the positioning rod 133 through the wire rope 162 to compress the positioning spring 134 into the positioning groove 132. By rotating the lower U-shaped frame 13, the positioning rod 133 is moved beyond the fixing groove 135 to the groove 15, and by rotating this U-shaped frame 13, the U-shaped frame 13 drives the positioning rod 133 to the slot 151, thus realizing the reset of the bullet rack 1 and facilitating the repeated use of the bullet rack 1.

[0029] By setting the arc block 145, the push rod 142 and the positioning rod 133 to be made of fluororubber material, it is to make the arc block 145, the push rod 142 and the positioning rod 133 made of fluororubber material have a certain hardness and elasticity. When the perforating charge 11 is launched, the impact generated by the explosion of the perforating charge 11 will be absorbed by the push rod 142 and the positioning rod 133 made of fluororubber material, avoiding the problem that the push rod 142 and the positioning rod 133 oscillate and bend in the positioning hole 122 and the positioning groove 132 due to the impact of the explosion of the perforating charge 11, so as to facilitate the user to recycle and reset the cartridge holder 1 subsequently, and further ensure the use effect and service life of the positioning rod 133 and the positioning groove 132. The arc block 145 made of fluororubber material can increase the grinding groove coefficient of the arc block 145, ensure that the arc block 145 is tightly abutted against the inner wall of the casing 12, and further improve the fixing effect of the arc block 145 and the casing 12.

[0030] As an embodiment of the present invention, a strip-shaped groove 17 is opened inside the U-shaped frame 13; a blocking strip 171 is slidably connected inside the strip-shaped groove 17; the blocking strip 171 is connected to the groove wall of the strip-shaped groove 17 through a connecting spring 172; a limiting groove 173 is opened at the bottom of the strip-shaped groove 17; a convex block 174 is slidably and sealingly connected inside the limiting groove 173; the convex block 174 is made of fluororubber material; an airbag 136 communicating with the limiting groove 173 is installed inside the fixing groove 135.

[0031] As an embodiment of the present invention, a chamfer is provided at one end of the blocking strip 171 close to the connecting spring 172.

[0032] As an embodiment of the present invention, an annular groove 111 is opened on the surface of the perforating charge 11; a clamping groove 18 communicating with the airbag 136 is opened on the side wall of the U-shaped frame 13; a clamping plate 181 is slidably and sealingly connected inside the clamping groove 18. During operation, during the installation of the perforating charge 11, the user inserts the perforating charge 11 into the U-shaped opening of the U-shaped frame 13. At this time, the perforating charge 11 inserted into the U-shaped opening of the U-shaped frame 13 will push the blocking strip 171 in contact with it to slide in the strip-shaped groove 17, causing the blocking strip 171 to squeeze the connecting spring 172 to the end of the strip-shaped groove 17 away from the perforating charge 11. When the blocking strip 171 slides in the strip-shaped groove 17, the blocking strip 171 will first approach the convex block 174 until the chamfered end of the blocking strip 171 contacts the convex block 174, causing the convex block 174 to be squeezed by the chamfered end of the blocking strip 171 and enter the limiting groove 173. Since the convex block 174 is slidably and sealingly connected in the limiting groove 173, when the convex block 174 enters the limiting groove 173, the convex block 174 will squeeze the air in the limiting groove 173, making the air in the limiting groove 173 in a compressed state until the blocking strip 171 passes over the convex block 174. At this time, the convex block 174 is pushed by the compressed air in the limiting groove 173 and extends out of the limiting groove 173. At this time, the perforating charge 11 is completely inserted into the U-shaped frame 13, and the blocking strip 171 is also blocked by the convex block 174.

[0033] When the rotating U-shaped frame 13 drives the positioning rod 133 to the fixed groove 135, the positioning rod 133 is pushed by the positioning spring 134 into the fixed groove 135, causing the positioning rod 133 to contact the airbag 136 in the fixed groove 135, so that the gas in the airbag 136 is squeezed by the positioning rod 133. Part of the gas in the airbag 136 flows into the limiting groove 173 communicated with it, and the other part flows into the card slot 18. At this time, the convex block 174 in the limiting groove 173 is pushed by the gas and enters the limiting groove 173. At this time, the convex block 174 no longer blocks the blocking strip 171, causing the blocking strip 171 to be pushed by the connecting spring 172 and move along the strip-shaped groove 17 in the direction close to the perforating charge 11, so that the blocking strip 171 pushes the perforating charge 11 to move in the direction close to the installation hole 121 of the casing 12. The gas flowing into the card slot 18 will push the clamping plate in the card slot 18 to extend out of the card slot 18, causing the clamping plate to slide into contact with the outer wall of the perforating charge 11. The gas in the card slot 18 is in a compressed state. Since the surface of the perforating charge 11 is provided with an annular groove 111, when the blocking strip 171 pushes the perforating charge 11 to drive the annular groove 111 on the surface to the clamping plate, the clamping plate will be pushed by the compressed gas and enter the annular groove 111, so that the clamping plate entering the annular groove 111 fixes the perforating charge 11 through the groove wall of the annular groove 111. At this time, the end of the perforating charge 11 away from the blocking strip 171 is inserted into the installation hole 121 of the casing 12.

[0034] In the prior art, there are also patents that solve the problem of low loading efficiency of the perforating charges 11 when the ammunition rack needs to be frequently rotated. For example, a perforator with the publication number CN117868756B has its projectile holes installed on the frame body, and the frame bodies can rotate relative to each other. This results in large oscillations and impacts on the frame body and the perforating charges 11 due to the impact force of the perforator during the firing of the perforating charges 11, which will cause friction and wear between the frame bodies, affecting the loading accuracy and service life. In addition, during the firing process of the perforator, the sequentially fired perforating charges 11 need to maintain a stable position in the projectile holes of the perforator to ensure accurate drilling. Excessive impact will cause small displacements of the perforating charges 11 before firing, resulting in the deviation of the perforation position, thereby affecting the final perforation effect.

[0035] In response to this, through the setting of the clamping plate and the mounting hole 121 of the sleeve 12, the perforating charges 11 inserted into the mounting hole 121 can be fixed in the mounting hole 121 of the sleeve 12, so that the sequentially fired perforating charges 11 can maintain a stable position in the perforator, preventing the deviation of the perforation position, and thus ensuring accurate drilling to improve the final perforation effect. In addition, the sleeve 12 is made of integrally formed alloy steel material, and the impact force of the perforating charges 11 will not cause damage to the sleeve 12. The push rod 142 and the positioning rod 133 of the ammunition rack 1 are both made of fluororubber material, which can absorb the impact force without causing impact damage problems. The clamping plate is also made of fluororubber material, so that the clamping plate can absorb the oscillating impact force transmitted by the perforating charges 11, thereby reducing the impact force on other U-shaped frames 13 and reducing the interference problem caused by the oscillating impact force between adjacent perforating charges 11, further ensuring that the sequentially fired perforating charges 11 can maintain a stable position in the perforator and thus be stably fired.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
