Abstract

The invention discloses a test cable control device. The test cable control device comprises a blowout prevention pipe installed on a base, wherein a pressing cap adjusting device is installed at theupper end of the blowout prevention pipe, a cable is arranged at the upper end of the pressing cap adjusting device, a cable clamping device is arranged on the cable, and the cable clamping device islocated above the pressing cap adjusting device; the cable clamping device is connected with a first motor, and the first motor is arranged on an up-down moving device; and the pressing cap adjustingdevice, the first motor and the up-down moving device are all electrically connected with a control box. According to the test cable control device, the cable is automatically pushed, the pushing force and the clamping force can be controlled, and the cable is not damaged under the limit pushing force; and remote visual adjustment is achieved, operation is easy, automatic adjustment does not needconfiguration personnel, the action condition of each motor can be directly observed, and the safety and reliability are high.

Description

technical field [0001] The invention relates to the technical field of oilfield test cables, in particular to a test cable control device. Background technique [0002] After the oil field is exploited in the middle and later stages, the method of water injection or polymer flooding into the formation is generally used to ensure the crude oil production. The injection well layered measurement and adjustment technology has been promoted and implemented in oilfields for many years, and has played a significant role in improving the economic benefits of oilfields. Layer-by-layer measurement and adjustment mainly uses cables to lower direct-reading measurement and adjustment instruments into the well to measure and adjust each layer, and the cables are lowered into the well from the ground through the blowout pipe. During the test operation, it is necessary for the tester to stand on the operating table to disassemble the blowout prevention plug, and to adjust the pressure cap ...
