Abstract

The invention relates to an underwater cable connector. An insertion head part is installed in an oil tube suspender, a piston A is arranged in an insertion head chamber in the oil tube suspender, the axle center of the piston A is sleeved on an insertion head conducting ring, two ends of the insertion head conducting ring are respectively provided with insertion head non-conductive parts, a spring A is sleeved at the periphery of a rear insertion head non-conductive part, and a cable A is connected with the insertion head conducting ring; a socket part is fixed on an underwater Christmas tree body and in a socket chamber of a socket shell, a socket body is sleeved in an internal guiding sleeve of the socket shell, a guiding column is arranged at the axle center of the socket body, and a socket conducting ring is arranged on the contact surface of the guiding column and the socket body; a spring B is arranged in a spring chamber of the socket body, and the bottom of the spring chamber is connected with a hydraulic pressure compensated cavity; a compensation liquid flow channel is additionally formed in the socket body; the socket conducting ring is connected with outside by the cable B; and the inner cavity of the compensated cavity shell is sequentially provided with the hydraulic pressure compensated cavity, and the piston B and a second spring chamber. The device realizes the underwater reliable insertion and pulling connection.

Description

technical field [0001] The invention belongs to the technical field of oil and gas drilling equipment, and relates to an underwater cable connector. Background technique [0002] As the production of offshore oil and gas continues to grow, the range and depth of the sea area and water depth of mining operations continue to expand. In order to meet the needs of offshore oil drilling and production in deep water, offshore oil and gas exploration and development technology and equipment also need to be continuously improved and perfected. During the normal production of offshore oil and gas fields, it is necessary to monitor the production flow rate, downhole pressure, temperature, etc., and sometimes, it is necessary to install downhole electric submersible pumps, booster pumps or multiple pumps to achieve continuous production of the oilfield; when operating in deep water, the above The equipment needs to be installed and connected underwater, and the traditional cable connec...
