Abstract

The invention belongs to the technical field of oil and gas field development engineering, and discloses a self-driven induction type oil pipe inner blanking plug. The self-driven induction type oil pipe inner blanking plug comprises a blanking plug body, wherein a pressure sensor, a driving wheel set, a driven wheel set and a sealing rubber cylinder are arranged on the blanking plug body, and a processing module, a first motor and a driving module are arranged in the blanking plug body; and the first motor, the driving module and the pressure sensor are electrically connected with the processing module, and the processing module is used for enabling the driving module to be started and closed according to a pressure pulse signal received by the pressure sensor. According to the self-driven induction type oil pipe inner blanking plug, the tripping-in depth can be designed through the processing module, the driving module is started by using the pressure pulse signal to enable the sealing rubber cylinder and slips to expand, one-time setting is achieved, the risk of manual operation errors is reduced, and the setting success rate is improved. The driving wheel set rotates to drive the oil pipe inner blanking plug to automatically reach a horizontal well section for setting, and the self-driven induction type oil pipe inner blanking plug is suitable for highly-deviated wells and horizontal wells.

Description

technical field [0001] The invention belongs to the technical field of oil and gas field development engineering, and in particular relates to a self-driven induction oil pipe internal plug. Background technique [0002] The existing plug in the downhole oil pipe is a mechanical plug, which is lowered into the well through a steel wire, and after reaching the setting position, the setting is realized through a series of actions of lifting and lowering the steel wire. In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the mechanical plug can only be used for setting in vertical wells, but not in inclined wells, and it is easy to encounter obstacles during the process of lifting and lowering the tool string, so it can be set in advance. The closure will affect the construction progress. Highly deviated wells cannot operate. Contents of the invention [0003] The present invention aims to s...
