Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of offshore oil equipment, and particularly relates to a profile control equipment pipeline arrangement scheme. BACKGROUND

[0002] At present, offshore oil production has entered the tertiary oil recovery stage in the petroleum industry in China, and a large number of profile control equipment is needed for injecting agents into oil wells, but most of the profile control equipment is still designed for land oil production, and few is specially optimized for offshore operation environment.

[0003] The profile control process needs several agents to be mixed and injected into the well bottom, the current offshore profile control equipment has high integration, and multiple agents are arranged on one pry, and when used, the agents are mixed in the pipeline and then injected into the well bottom, but part of the agents will be caked and left in the pipeline when mixed in the pipeline, which needs to be cleaned frequently, consumes time and manpower, and because the offshore equipment is arranged compactly, multiple pipelines are usually arranged on one pry, so if one pipeline is repaired, the whole needs to be stopped, which affects the work progress.

[0004] Therefore, it is necessary to provide a profile control equipment pipeline arrangement scheme to clean the pipeline without disassembling the pipeline, and to use other pipelines without affecting the use of other pipelines when repairing a single pipeline. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at solving the problem that the existing profile control equipment needs to be stopped as a whole when one pipeline is cleaned, which affects the work progress, and provides a profile control equipment pipeline arrangement scheme.

[0006] The technical scheme of the utility model is:

[0007] A profile control equipment pipeline arrangement scheme, which comprises a main pipeline and multiple discharge pipelines connected with the main pipeline, a metering pump and a shut-off valve are installed on each discharge pipeline, the shut-off valve is located at one end of the discharge pipeline close to the main pipeline, a first vent valve and a second vent valve are installed on each discharge pipeline, the first vent valve is located between the metering pump and the shut-off valve, and the second vent valve is located at the connection between the discharge pipeline and the main pipeline.

[0008] Further, a pressure relief valve is installed on each discharge pipeline, and the pressure relief valve is located between the shut-off valve and the metering pump.

[0009] Further, a flow meter is installed on each discharge pipeline, and the flow meter is located between the pressure relief valve and the first vent valve.

[0010] Further, a damper is installed on each discharge pipeline, and the damper is located between the pressure relief valve and the flow meter.

[0011] Further, the first vent valve and the second vent valve are fixedly connected with the discharge pipeline through connecting flanges.

[0012] Furthermore, the shut-off valve and the metering pump are fixedly connected to the discharge pipeline via a connecting flange.

[0013] Furthermore, the pressure relief valve is fixedly connected to the discharge pipeline via a connecting flange.

[0014] Furthermore, the flow meter is fixedly connected to the discharge pipeline by screws.

[0015] Furthermore, the damper is fixedly connected to the discharge pipeline by screws.

[0016] The utility model discloses a pipeline arrangement scheme for profile control equipment. In normal use, the shut-off valve is closed, the two vent valves are both open, and the metering pump discharges the medicine through the discharge pipeline into the main line for operation; when the shut-off valve is closed, the discharge pipeline is completely separated from the main line, and then the first vent valve between the metering pump and the shut-off valve is opened, and the sewage in the discharge pipeline can be discharged through the first vent valve, so that the normal operation of the main line is not affected when the discharge pipeline is repaired, and other discharge pipelines can still be connected to the main line to achieve normal operation; when the shut-off valve is closed, the second vent valve between the shut-off valve and the main line is opened, and the discharge pipeline is completely separated from the main line. Open, the sewage such as the agglomerated residue in the main line can be discharged through the vent valve. Since the discharge pipeline has been disconnected from the main line at this time, the discharge of sewage will not affect the metering pump, so the discharge of sewage can be completed without opening the metering pump. Compared with the traditional technology, this technical solution uses the first vent valve and the second vent valve to realize the discharge of agglomerated residue and other sewage, and there is no need to disassemble the pipelines for cleaning, which saves time and manpower. At the same time, it also realizes the separation of the discharge pipeline and the main line, so that the main line can still work and operate with other normally operating discharge pipelines when the single discharge pipeline is cleaning the agglomeration, avoiding the overall shutdown and speeding up the work progress.

[0022] In order to make the technical means, technical features, purpose of the utility model and technical effects achieved by the utility model easier to understand, the utility model is further explained below with reference to specific illustrations.

[0023] Example 1:

[0024] like Figure 1 As shown, this embodiment provides a pipeline layout scheme for profile control equipment, including a main line 1 and multiple discharge pipelines 2 connected to the main line 1, each discharge pipeline 2 is installed with a metering pump 3 and a shut-off valve 4, the shut-off valve 4 is located at one end of the discharge pipeline 2 close to the main line 1, each discharge pipeline 2 is installed with a first vent valve 5 and a second vent valve 6, the first vent valve 5 is located between the metering pump 3 and the shut-off valve 4, and the second vent valve 6 is located at the connection between the discharge pipeline 2 and the main line 1.

[0025] Preferably, each discharge pipeline 2 is also equipped with a pressure relief valve 7, which is located between the shut-off valve 4 and the metering pump 3. Preferably, each discharge pipeline 2 is equipped with a flow meter 8, which is located between the pressure relief valve 7 and the first vent valve 5. Preferably, each discharge pipeline 2 is equipped with a damper 9, which is located between the pressure relief valve 7 and the flow meter 8. Preferably, the first vent valve 5 and the second vent valve 6 are fixedly connected to the discharge pipeline 2 via a connecting flange. Preferably, the shut-off valve 4 and the metering pump 3 are fixedly connected to the discharge pipeline 2 via a connecting flange. Preferably, the pressure relief valve 7 is fixedly connected to the discharge pipeline 2 via a connecting flange. Preferably, the flow meter 8 is fixedly connected to the discharge pipeline 2 via screws. Preferably, the damper 9 is fixedly connected to the discharge pipeline 2 via screws.

[0026] In normal use, such as Figure 2 As shown, the shut-off valve 4 is closed, the two vent valves are opened, and the metering pump 3 discharges the reagent through the discharge line 2 into the main line 1 for operation; Figure 3 As shown, when the shut-off valve 4 is closed, the discharge line 2 is completely separated from the main line 1. Then, the first vent valve 5 between the metering pump 3 and the shut-off valve 4 is opened, and the sewage in the discharge line 2 can be discharged through the first vent valve 5, so that the normal operation of the main line 1 is not affected when the discharge line 2 is repaired. Other discharge lines 2 can still be connected to the main line 1 to achieve normal operation. Moreover, when the flow meter 8, damper 9 and pressure relief valve 7 and other components are repaired, the metering pump 3 can also be shut down. Since the shut-off valve 4 is closed and the first vent valve 5 is opened, whether it is cleaning the agglomerate residue at the pressure relief valve 7 or replacing the flow meter 8, the sewage generated can be discharged through the first vent valve 5, thereby not affecting the operation of the main line and improving the maintenance efficiency. Figure 4As shown, when the shut-off valve 4 is closed, the second vent valve 6 between the shut-off valve 4 and the main line 1 is opened. At this time, the discharge line 2 is completely separated from the main line 1, and the sewage such as the agglomerated residue in the main line 1 can be discharged through the vent valve. Since the discharge line 2 has been disconnected from the main line 1 at this time, the discharge of sewage will not affect the metering pump 3, so the discharge of sewage can be completed without starting the metering pump 3. Compared with the traditional technology, the present technical solution utilizes the first vent valve 5 and the second vent valve 6 to realize the discharge of sewage such as agglomerated residue, and there is no need to disassemble the pipelines for cleaning, which saves time and manpower. At the same time, the discharge line 2 is separated from the main line 1, so that the main line 1 can still work and operate with other normally operating discharge pipelines 2 when the single discharge line 2 is cleaning the agglomerates, thereby avoiding overall shutdown and speeding up work progress.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. In other words, any equivalent changes and modifications made within the scope of the present invention's patent application should fall within the technical scope of the present invention.
