Annular wellhead flow device

Abstract

The invention relates to the technical field of oil exploitation, and discloses an annular wellhead flow device. The device comprises a combination valve body, the left side and the right side of the combination valve body fixedly communicate with a connecting pipe and an oil outlet pipe correspondingly, the outer surface of the connecting pipe is movably sleeved with a mounting pipe, and the inner surface of the mounting pipe is fixedly connected with a connecting plate; and the inner side face of the connecting plate is fixedly connected with a mounting disc, and the outer surface of the mounting disc is movably sleeved with a movable ring. According to the annular wellhead flow device, the outer side of the connecting pipe is sleeved with the mounting pipe, mounting is achieved through a locking sleeve, a connecting plate is additionally arranged on the inner surface of the mounting pipe, the outer surface of the mounting disc on the side face of the connecting plate is movably sleeved with the movable ring, the side face of the movable ring is connected with blades, and the blades rotate when petroleum flows; and a fixed rod on the end face of the movable ring drives a stirring plate to rotate, stirring during petroleum circulation is achieved, mixing and uniform stirring of petroleum are improved, the circulation efficiency is improved, and the use effect is good.

AI Technical Summary

Problems solved by technology

The well site pipelines installed with valves are criss-crossed, and the functional valves are scattered and installed, covering a large area, requiring heavy installation workload, serious oil theft, and difficult production management. In order to solve these problems, annular wellhead process devices have been widely used in oil fields. application

[0003] During the use of the existing annular wellhead process device, since the connecting pipe is used to connect the oil at the Christmas tree, the oil entering into the process device has poor mixing and high viscosity, which makes the flow rate of the oil circulating in the process device slow and reduces It reduces the transportation efficiency, and the closed connecting pipe is difficult to comb the oil under the installation situation, and the use effect is not good

[0004] In addition, during the use of the existing annular wellhead flow device, due to the decrease in temperature of the oil circulating from the Christmas tree, in winter or when the ambient temperature is low in part of the time, the low temperature causes the viscosity of the oil to increase, reducing the viscosity of the oil. The flow rate makes it easy to block the pipeline, which reduces the oil output efficiency of the wellhead, and the use effect is not good

[0005] On the other hand, in the existing annular wellhead process device, when the combination valve body is discharging oil, the oil flowing out from the oil outlet pipe is connected to the external pipeline. However, the actual data of the oil flowing out of the combination valve body is not clear. It is difficult to take oil samples out of closed pipelines, and it is impossible to effectively obtain oil production data, which affects the understanding of oil extraction, and the use effect is not good
