On September 16, 2026, our company's rigid-cable-conveyed electric tool assembly, in combination with the electric tool, successfully completed its test. The well is a highly deviated well with a 70° deviation angle. The cable precisely reached the designed run-in depth of 1850 m. This test verified the cable's outstanding passing capability, resolved the pain points of conventional soft cables — insufficient thrust and difficult conveyance in horizontal wells — and demonstrated such features as strong controllability and repeated run-in/run-out. It lays a foundation for subsequent operations in wells with even larger deviation angles and for improving the success rate of testing.
The success of this rigid-cable-conveyed electric tool test fills the technical gap in cable-conveyed downhole electric equipment. Next, we will continue to optimize the tool structure and control program in terms of details, and steadily improve the supporting operating procedures, so as to provide new equipment and new technical support for the treatment of complex wells and for improving the quality and efficiency of workover operations in the oilfield.
