Abstract

A fluid separation device, well structure, and oil or gas production method. During operation, when a fluid separation device (010) moves up to an upper end of a well (201), a core tube (400) impacts an upper impact device (202), such that the core tube (400) moves from a closed position to an open position. At the same time, a control device (600) drives a valve plate (500) to rotate forward by a first predetermined angle to increase a flow area of a fluid passageway (401). Oil or gas below the fluid separation device (010) can pass through the fluid passageway (401) to above the fluid separation device (010), thus reducing a force-receiving area of the fluid separation device (010), so as to enable the fluid separation device (010) to quickly descend to the well bottom without shut-in of the well.

Description

Technical field [0001] The invention relates to the technical field of oil or natural gas exploitation, in particular to a fluid separation device, a well structure and a method for producing oil or natural gas. Background technique [0002] During the development of oil or natural gas wells, when the oil or natural gas production in the well is low, the oil or natural gas cannot lift a large amount of liquid to the ground, which will form a certain height of liquid accumulation at the bottom of the well, thereby reducing the productivity of the oil or natural gas well. It even caused oil or natural gas wells to stop blowing. [0003] A related technology known to the inventor provides a fluid separation device. A plurality of partitions are arranged on the periphery of the fluid separation device, and these partitions are always in contact with the inner wall of the well under the action of the elastic member to form a seal. In this way, the pressure generated by the fluid below...
