Oil pipe supporting device for intelligent separate-layer oil extraction and using method thereof

Abstract

The invention discloses an oil pipe supporting device for intelligent separate-layer oil extraction and a using method thereof, and relates to the technical field of oil and gas equipment. The oil pipe supporting device comprises a cushioning mechanism, the cushioning mechanism comprises a mechanism wall, the bottom of the mechanism wall is fixedly connected with a ball, the ball is made of non-Newtonian fluid. An elastic wall is fixedly connected to the inner side face of the mechanism wall, a rib plate is fixedly connected to the surface of the mechanism wall, a baffle is arranged at the top of the inner side face of the mechanism wall, a connector is fixedly connected to the inner side face of the mechanism wall, and the top end of the connector penetrates through the baffle. According to the oil pipe supporting device for intelligent separate-layer oil extraction and the using method thereof, through cooperative use of the cushioning mechanism, an anti-deposition mechanism, a flexible mechanism, a thermal compensation mechanism and other mechanisms, the problems that the supporting device vibrates unstably due to mechanical operation in an oil extraction area, an oil pipe is prone to being damaged at the connecting position of the oil pipe and the supporting device, and the heat expansion and cold contraction amount of the oil pipe cannot be effectively compensated are solved.

Description

technical field [0001] The invention relates to the technical field of oil and gas equipment, in particular to an oil pipe support device for intelligent layered oil production and its use method. Background technique [0002] The oil pipe is a pipeline that transports crude oil and natural gas from the oil and gas layer to the surface after the drilling is completed. It is used to withstand the pressure generated during the production process. Layered oil production refers to the use of packers to separate oil layers in production wells that exploit multiple oil layers. In order to reduce or eliminate interlayer interference, the perforation section of oil and gas production wells generally includes several small oil layers. , their dynamic characteristics are different, even in the same small oil layer, the dynamic characteristics of the upper and lower layer sections will have considerable differences. Based on the above description, the inventors found that the existing...
