Packer for oil exploitation

Abstract

The invention discloses a packer for oil exploitation, and relates to the technical field of oil exploitation equipment. The packer comprises a connecting pipe and an operating rod, an embedded pipe fixedly sleeves the right end of the connecting pipe, a rubber bag fixedly sleeves the outer part of the embedded pipe, and a socketed pipe movably sleeves the side of the embedded pipe. According to the packer for oil exploitation, through cooperative use of a connecting joint, a connecting groove, a connecting spring and a connecting block, the connecting joint can be inserted into the connecting pipe under the action of the operating rod, meanwhile, the connecting joint is powered on, after the connector is electrified, suction force is generated to suck the connecting block out of the interior of the connecting pipe and enable the connecting block to be embedded into the connecting groove, then the operating rod can be pulled to drive the connecting pipe to move the packer, electrification is ended when the connecting joint needs to be taken out of the interior of the packer, the connecting block resets under the action of the elastic force of the connecting spring, and connection between the connecting joint and the connecting pipe is relieved.

Description

technical field [0001] The invention relates to the technical field of oil exploitation equipment, in particular to a packer for oil exploitation. Background technique [0002] Petroleum is an industrial term, which is relative to mineral resources. It is commonly referred to as the petroleum industry, which is a mineral resource industry. In the process of petroleum exploration, oil reserves are calculated and determined according to the degree of exploration and proven conditions. Petroleum reserves are geological Exploration results are a kind of original mineral resources to be developed. Crude oil is the oil that is mined in the rock formation and keeps its original physical and chemical form. It is the primary product of the petroleum industry and realizes its use value. It is the result of oil field development, and crude oil production is the production of a mineral resource that has been developed. [0003] The packer is an essential equipment in the process of oil...

AI Technical Summary

Problems solved by technology

[0003] The packer is an essential equipment in the process of oil exploitation. It refers to the downhole tool connected to the downhole pipe string and used to isolate the oil pipe and the casing of the oil and gas well or the annular space of the open hole wall. However, the common ones on the market are There are still some deficiencies in the use of packers. First, the operation of common packers moving inside oil wells is relatively cumbersome. To shorten the service life of the packer, we designed a packer for oil development to solve the above problems
