The utility model aims to solve the problems in the prior art and provides a composite multifunctional eccentric wellhead for directional oil extraction test.
The aim of the utility model can be achieved by the following technical scheme:
a directional oil extraction test compound multifunctional eccentric wellhead comprises an oil extraction pipe body; the oil extraction pipe is characterized in that an oil outlet pipe seat is arranged on the oil extraction pipe body, an oil outlet pipeline communicated with the oil extraction pipe body is arranged on the oil outlet pipe seat, a wellhead main body is installed on the oil outlet pipe seat, the wellhead main body is connected with the oil outlet pipe seat through a bearing, an oil extraction channel and a test channel are arranged on the wellhead main body, the oil extraction channel is arranged vertically, the test channel is arranged obliquely, a flange cover plate is arranged on the wellhead main body, oil pipe hangers are installed on oil extraction channel openings respectively, and measuring instruments are installed on the test channel openings.
Furthermore, the oil outlet tube seat adopts a four-way structure, and the interfaces at the left side and the right side are respectively connected with the pipeline pressure testing device and the oil extraction device.
Furthermore, the oil extraction pipeline of the measuring instrument is welded on the flange cover plate.
Further, five sealing rings are arranged on the wellhead main body and are respectively positioned on the upper side and the lower side of the bearing and the upper side and the lower side of the oil outlet pipeline.
Further, the included angle between the central line of the oil extraction channel and the central line of the test channel is 4-6 degrees.
Compared with the prior art, the utility model provides a directional oil extraction test composite multifunctional eccentric wellhead, which is provided with an oil extraction channel and a test channel, wherein one oil extraction channel and one test channel are used for oil extraction, one test channel is used for testing, the other oil extraction channels are not affected, the production efficiency is improved, and the eccentric wellhead device is provided with a bearing so that a test tube and an oil extraction tube can rotate around an oil extraction tube body, and the problems of blocking, blocking and winding the oil tube in the process of removing an instrument are overcome.
