Description

Technical Field

[0001] This invention relates to the field of cementing operation technology and is an automated cementing multi-channel integrated control device. Background Technology

[0002] Currently, in domestic cementing operations, high-pressure pipelines are commonly used to directly connect the surface cementing equipment to the wellhead cement head. If there are multiple types of working fluids, multiple high-pressure pipelines need to be connected between the cementing equipment and the cement head, or multiple high-pressure pipelines need to be connected using tee fittings. This construction method requires more control accessories, connecting multiple pipelines, and is time-consuming and labor-intensive to install. Furthermore, the working fluid channels connecting the high-pressure pipelines usually cannot be closed manually or automatically, making it impossible to quickly switch between multiple high-pressure pipelines. This is especially true in automated cementing operations, where it is difficult to automatically control the opening and closing of multiple pipeline channels. In addition, when multiple cement trucks are used to mix cement slurry simultaneously, the density of the mixed cement slurry is inconsistent, which affects the cementing quality.

[0003] Chinese patent document CN 107152257 A discloses a multi-channel valve, characterized by comprising a distributor with a closed structure and a plurality of first inlet pipes, a distribution disc fixedly connected within the distributor, a metering channel disposed on one side of the distribution disc, and a distribution arm rotatably disposed on the other side of the distribution disc. The distribution disc is provided with pipe holes corresponding to the first inlet pipes one by one. The distribution arm is provided with a U-shaped channel, one end of which is dynamically sealed and connected to the metering channel, and the other end is dynamically sealed and connected to one end of a first inlet pipe whose pipe hole is not connected. This multi-channel valve is used in the field of oilfield production metering and management technology. When used in the field of cementing construction, it has the following problems: (1) The channel structure is complex, and cement slurry is easily blocked at the U-shaped channel; (2) It cannot withstand excessive pressure, and the seal is easily failed at the connection of the U-shaped channel.

[0004] Chinese patent document CN 203082272 U discloses a three-way valve, characterized by including a valve body and a valve core, the valve core being located within the valve body, the valve body having one valve body inlet and two valve body outlets, the valve core having a valve core fluid channel, and the valve core rotating within the valve body via an actuator connected to the valve core. The valve core fluid channel is connected to the valve body inlet and any one of the valve body outlets; after the valve core rotates, the valve core fluid channel is again connected to the valve body inlet and the other valve body outlet. This three-way valve is used in the field of material transportation, but its use in cementing operations presents the following problems: (1) This three-way valve can only achieve dual-channel switching, which is insufficient for multi-channel working fluid transportation in cementing operations; (2) It cannot achieve the function of indicating working status; (3) The valve core end face is in sliding contact with the valve body, resulting in high rotational friction resistance, and it cannot rotate after prolonged use. Summary of the Invention

[0009] The above may also include forward blades and reverse blades. The grouting pipe is Y-shaped, and forward blades and reverse blades are provided at intervals on the inner side of the rear part of the grouting pipe.

[0010] The above may also include an upper bearing and a lower bearing.

Detailed Implementation

[0022] The present invention is not limited to the following embodiments, and specific implementation methods can be determined according to the technical solutions and actual conditions of the present invention.

[0023] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0024] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0025] Example 1: As shown in the attached document Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, the automated cementing multi-channel integrated control device includes a main valve body 1, a rotary valve core 2, a pressure cap 13, and a drive device. The main valve body 1 has an upward-opening mounting cavity 3, and the rotary valve core 2 is located above the mounting cavity 3. The rotary valve core 2 is rotatably connected to the main valve body 1. The rotary valve core 2 has a downward-opening connecting cavity 4. The upper outer side of the rotary valve core 2 is provided with a pressure cap 13 that is fixedly installed together with the upper outer side of the main valve body 1. The rotary valve body 2 is rotatably connected to the pressure cap 13. The upper end of the rotary valve core 2 is provided with a drive device that enables it to rotate. The outer side of the main valve body 1 has six through mounting holes along the circumference. The mounting hole at the lowest position is the liquid outlet hole 5, and the mounting holes above the liquid outlet hole 5 are all liquid inlet holes. The lower end of the rotary valve core 2 is located above the liquid outlet hole 5, and a guide hole 6 is provided on the front side of the rotary valve core 2 corresponding to the height position of each liquid inlet hole. During use, the corresponding working fluid pipeline is connected to the outside of the main valve body 1 at each mounting hole position. By setting six mounting holes with the outlet hole 5 at the bottom, when the guide hole 6 connects to the five inlet holes at different positions, the working fluid in the pipeline connected to the corresponding inlet hole flows sequentially through the guide hole 6, the connecting cavity 4, and the mounting cavity 3 before exiting from the pipeline connected to the outlet hole 5. This allows for rapid switching between different working fluids and effectively solves the problem of complex pipelines caused by the variety of working fluids in existing cementing operations. Depending on the requirements, the five inlet holes can be set at the same height plane, in which case the number of guide holes 6 is one; or the five inlet holes can be set at five different height planes, in which case the number of guide holes 6 is five.

[0026] The above-mentioned automated cementing multi-channel integrated control device can be further optimized and / or improved according to actual needs:

[0027] Example 2: As shown in the attached document Figure 1 , 2As shown in Figures 3 and 4, the system also includes a slurry replacement pipe 7, a flushing fluid pipe 8, a separation fluid pipe 9, a pilot slurry pipe 10, an injection pipe 11, and an outlet pipe 12. The outer side of the middle section of the main valve body 1 is provided with four height positions, decreasing sequentially from top to bottom: a first height position, a second height position, a third height position, a fourth height position, a fifth height position, and a sixth height position. The inlet hole on the left rear side of the main valve body 1 corresponding to the first height position is a slurry replacement hole, and a slurry replacement pipe 7 is fixedly installed on the outer side of the main valve body 1 corresponding to the slurry replacement hole position. The inlet hole on the right rear side of the main valve body 1 corresponding to the second height position is a flushing fluid hole, and a flushing fluid pipe 7 is fixedly installed on the outer side of the main valve body 1 corresponding to the flushing fluid hole position. The main valve body 1 at the third height position has a liquid inlet on the right front side, which is an isolation liquid inlet. An isolation liquid connector 9 is fixedly installed on the outside of the main valve body 1 at the position of the isolation liquid inlet. The main valve body 1 at the fourth height position has a liquid inlet on the left front side, which is a pilot slurry inlet. An pilot slurry connector 10 is fixedly installed on the outside of the main valve body 1 at the position of the pilot slurry inlet. The main valve body 1 at the fifth height position has a liquid inlet on the front side, which is a grouting hole. An grouting connector 11 is fixedly installed on the front side of the main valve body 1 at the position of the grouting hole. The main valve body 1 at the sixth height position has a liquid outlet 5 on the rear side. An liquid outlet connector 12 is fixedly installed on the rear side of the main valve body 1 at the position of the liquid outlet 5. During use, due to the large overall liquid output, the liquid outlet pipe 12 is positioned at the sixth height. Since the cement slurry injection volume is large, the grouting pipe 11 is positioned at the fifth height. For stability reasons, the grouting pipe 11 and the liquid outlet pipe 12 are positioned opposite each other to prevent sudden pressure changes from causing the embodiment to tip over. Furthermore, to maximize the replacement of cement slurry within the device, the slurry replacement pipe 7 is positioned at the first height. To maximize the cleaning of the device's interior, the flushing fluid pipe 8 is positioned at the second height. Depending on requirements, the main valve body 1 can be a regular hexagonal prism to facilitate the welding and fixing of each pipe.

[0028] Example 3: As shown in the attached document Figure 1 , 5 As shown, it also includes forward blades 21 and reverse blades 22. The grouting pipe 11 is Y-shaped, and forward blades 21 and reverse blades 22 are spaced apart on the inner rear side of the grouting pipe 11. During use, the cement slurry from the two cement trucks flows in through the two branch pipes set at the front of the grouting pipe 11 and mixes in the main pipe set at the rear. The two cement slurries are mixed by spiral motion through the forward blades 21, and then turbulence is generated when they pass through the reverse blades 22 due to the opposite rotation direction, so that the two cement slurries are fully mixed. The mixed cement slurry flows in through the grouting hole, flows through the connecting cavity 4 and flows out through the liquid outlet hole 5, effectively solving the problem of inconsistent cement slurry density affecting the cementing quality when multiple cement trucks are used to mix cement slurry at the same time.

[0029] Example 4: As shown in the appendix Figure 2 As shown, it also includes an upper bearing 15 and a lower bearing 16. The upper bearing 15 is provided between the rotary valve core 2 and the pressure cap 13 at the position above the guide hole 6, and the lower bearing 16 is provided between the rotary valve core 2 and the main valve body 1 at the position below the guide hole 6. During use, by setting the upper bearing 15 and the lower bearing 16, the friction force when the rotary valve core 2 rotates is reduced.

[0030] Example 5: As shown in the attached document Figure 2 As shown, it also includes O-ring seals 17. At least one O-ring seal 17 is provided vertically between the rotary valve core 2 and the main valve body 1 at positions above and below each through hole 6. During use, by setting the O-ring seals 17, each channel can be independently connected.

[0031] Example 6: As attached Figure 1 , 2 As shown in Figures 3 and 4, the system also includes a control module 14. The driving device consists of a drive motor 18 and a reducer. The output shaft of the drive motor is connected to the input end of the reducer, and the lower end of the reducer has a lower output end. The upper end of the rotary valve core 2 is connected to the lower output end of the reducer. The control module 14 is connected to the drive motor 18. During use, the control module 14 facilitates the control of the rotation of the drive motor 18, ensuring that the guide hole 6 corresponding to the required process is connected to the liquid outlet hole 5. Depending on the requirements, the rotation angle of the rotary valve core 2 can be controlled by the control module 14 to control the number of rotations of the drive motor 18, or it can be achieved using a stepper motor.

[0032] Example 7: As attached Figure 1 , 2 As shown in Figures 3, 4, and 6, a workstation display device is also included. This device comprises an indicator box, an indicator disc 19, a pointer shaft, and an indicator needle 20. The indicator box is located on the upper side of the drive motor 18, and the indicator disc 19 is located inside it. A pointer shaft with its lower end positioned below the center of the indicator disc 19 is located in the center of the disc. The indicator needle 20 is fixedly mounted on the outer side of the upper end of the pointer shaft. An upper output end is located at the upper end of the reducer, and the lower end of the pointer shaft is connected to the upper output end of the reducer. The pointer shaft rotates synchronously with the rotary valve core 2. During use, by setting the indicator disc 19, the current working position can be indicated as the indicator needle 20 rotates with the rotary valve core 2. Depending on the requirements, the indicator disc 19 is marked with corresponding connector labels for the positions of the slurry replacement connector 7, flushing fluid connector 8, isolation fluid connector 9, pilot slurry connector 10, grouting connector 11, and outlet connector 12.

[0033] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.

[0039] (5) Cement grouting: The control module 14 controls the drive motor 18 to rotate the guide hole 6 of the rotary valve core 2 to the direction of the grouting pipe 11. After the cement head and cement truck are ready, the cement grouting operation can begin. The cement grout from the two cement trucks flows into the two branch pipes of the grouting pipe 11 and mixes in the main pipe. Through the forward blade 21 and the reverse blade 22, the two cement grouts are fully mixed and uniform. The mixed cement grout flows into the connecting cavity 4, the installation cavity 3 and the liquid outlet 5 from the grouting hole, and then from the liquid outlet pipe 12 to the cement head of the drilling platform for cement grouting operation.

[0040] (6) Grouting: The control module 14 controls the drive motor 18 to rotate the guide hole 6 of the rotary valve core 2 to the direction of the grouting pipe 7. After the cement head and cement truck are ready, the grouting operation can begin.

[0041] (7) Cleaning the pipeline: The control module 14 controls the drive motor 18 to rotate the through hole 6 of the rotary valve core 2 to the direction of the liquid outlet pipe 12. The liquid outlet pipe 12 is connected to the backflushing pipeline. The control module 14 controls the drive motor 18 to rotate the rotary valve core 2 to the five pipe directions respectively for backflushing cleaning. After cleaning, the control module 14 controls the drive motor 18 to rotate the through hole 6 of the rotary valve core 2 to the direction of the liquid outlet pipe 12. After depressurizing and disassembling the pipeline, the clean water in the device is drained, and the cementing operation is completed.

[0042] This invention, through the setting of a rotating structure, realizes remote automatic control switching of pilot grout injection, flushing fluid injection, isolation fluid injection, cement grout injection, and grout replacement pipelines, improving the timeliness during complex construction; it integrates the working fluid outlet into a single pipeline, avoiding the connection of too many high-pressure pipelines and control accessories between the ground and the drilling platform, thus saving a significant amount of manpower and resources; by setting forward blades 21 and reverse blades 22 in the grouting connector 11, when multiple cement trucks are simultaneously mixing cement grout and the density of the mixed cement grout is inconsistent, it can be mixed again to achieve uniformity, improving the cementing quality.
