Full-automatic oil pipe inner diameter inspection gauge

Abstract

The invention provides a full-automatic oil pipe inner diameter inspection gauge. One end of a guide structure of the gauge is in threaded connection with one end of a shell; one end of the guide structure is electrically connected to one end of an automatic power supply structure; a plurality of centralizing wheels are mounted on the peripheral wall of the automatic power supply structure in the circumferential direction at equal intervals; one end of a switch positioning seat is adhered to the other end of the automatic power supply structure; a touch microswitch is embedded in a through hole of the switch positioning seat; and an operation button of the touch microswitch extends out of the shell and can abut against the inner wall of an oil pipe, and the touch microswitch can be electrically connected to the automatic power supply structure through a conductive spring. One end of a first driving structure is adhered to the other end of the switch positioning seat; the touch microswitch is electrically connected with the first driving structure and used for controlling the first driving structure to be turned on or turned off; a second driving structure is mounted in an inner cavity of the shell; and the touch microswitch is electrically connected with the second driving structure. The device is easy to operate, and the labor intensity of workers can be relieved.

Description

technical field [0001] The application relates to the field of oil and gas well operations, in particular to a fully automatic oil pipe inner diameter inspection gauge. Background technique [0002] Fuling shale gas field, as the main battlefield of Jianghan Oilfield to maintain oil and strive for gas, has entered the middle stage of development, and the pressure drop has a great impact on production. The use of gas lift drainage is an important means to increase production. Therefore, the inspection and control operation is based on gas lift drainage. key link. There are about 500 gas wells in the Fuling shale gas field, with an average well depth of about 2400-2800 meters. Each well uses about 340-400 pipes. Based on the calculation of 200 wells inspected and inspected every year, the ground inspection pipes are about 80,000 or more. If According to the current means of testing, this process alone wastes 2,400 hours of manpower every year, which is not only labor-intensiv...
