Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 and 2, the oil pressure gauge connecting line of the present embodiment includes: the oil pressure gauge 10, the connecting elbow 20 and the sweeping structure 30. Therein, the oil pressure gauge 10 is used to measure the oil pressure in the flowline 120 of the production well. The first end 22 of the connection elbow 20 communicates upwardly with the flowline 120 and the second end 23 of the connection elbow 20 communicates upwardly with the oil pressure gauge 10. The sweep structure 30 has an air outlet that communicates with the channel at the corner 21 of the connecting elbow 20, the air outlet being directed toward the first end 22 of the connecting elbow 20.
By applying the technical scheme of the embodiment, the oil pressure gauge connecting pipeline comprises the sweeping structure, and the gas outlet of the gas sweeping structure 30 can be swept out, so that the silt deposited at the corner 21 of the connecting elbow is blown to the first end 22 of the connecting elbow 20, and finally the silt is discharged into the oil outlet pipeline 120 from the first end 22 of the connecting elbow 20, and flows out of the pipeline along with oil gas. The structure can avoid the phenomenon that silt thoroughly blocks the corner 21, ensure that the oil pressure gauge 10 displays real and accurate data, and does not influence the management and daily operation of an oil well. In addition, if sediment deposits at the corner 21, only the sweeping structure is needed to sweep, and the connecting elbow 20 is not needed to be detached, so that the cleaning efficiency is improved, and the labor intensity of operators is reduced.
As shown in fig. 1 and 2, in the present embodiment, the flushing structure 30 includes a first vent pipe 31, a first end 311 of the first vent pipe 31 is communicated with the oil casing annulus 110 of the production well, a second end 312 of the first vent pipe 31 is connected with the corner 21, and a nozzle of the second end of the first vent pipe 31 forms an air outlet. The structure utilizes the gas in the oil sleeve annulus 110 to purge, and an air supply device is not needed to be added independently, thereby effectively utilizing the existing conditions and reducing the cost.
As shown in fig. 1 and 2, in the present embodiment, the flushing structure 30 further includes a valve 32, and the valve 32 is disposed on the first vent pipe 31. Above-mentioned structure can effective control sweep, when needs sweep, opens the valve, closes the valve when need not sweeping, the operating personnel of being convenient for operation. It should be noted that the oil well includes a flow-through phase and an oil pumping phase. The air pressure of the oil sleeve ring of the self-blowing oil well is large, the valve is in a normally open state, at the moment, gas in the oil sleeve annulus 110 can enter the sweeping structure 30 along the direction of an arrow b in fig. 2 and is continuously swept out from the gas outlet of the sweeping structure 30, so that silt cannot enter the connecting bent pipe 20 under the impact of the gas, and the phenomenon that settled sand is accumulated at the corner 21 can be thoroughly avoided. The oil pumping well has a certain gas pressure in the air of an oil jacket ring, the valve is in a normally closed state, when purging is needed, the valve is opened, gas can flush the gas outlet of the structure 30, so as to blow silt deposited at the corner 21 of the connecting elbow to the first end 22 of the connecting elbow 20, and finally the silt is discharged into the oil outlet pipeline 120 from the first end 22 of the connecting elbow 20 to flow out of the pipeline along with oil gas in the direction of an arrow a in fig. 2. Therefore, the structure can avoid the phenomenon that silt completely blocks the corner 21 under the action of the sweeping structure 30 no matter the self-blowing oil well in the self-blowing stage or the oil pumping oil well in the oil pumping stage, so that the display data of the oil pressure gauge 10 is real and accurate, and the management and daily operation of the oil well are not influenced.
