Abstract

The invention discloses a falling-off-prevention connecting structure of a deep sea petroleum detector. The falling-off-prevention connecting structure comprises a steel wire cable, a cable connectingend, a measuring instrument end head, a fixing head connecting block, a first clamping block and a first clamping groove. The steel wire cable is fixed to the cable connecting end, the lower end of the cable connecting end is overall connected to a measuring instrument connecting and fixing head, and the fixing head connecting block is arranged on the outer circle of the measuring instrument connecting and fixing head; and a measuring instrument rear body is connected to and arranged at the lower end of the measuring instrument end head, and the first clamping groove and a second clamping groove are formed in the outer circle of the measuring instrument end head. The falling-off-prevention connecting structure of the deep sea petroleum detector is fixed through double bayonets and the double clamping grooves, so that the problem that as for an existing petroleum detector connecting structure, in the upward and downward processes, a bayonet in the connecting end is likely to fall off duet to generated torsion is solved, and using safety is improved.

Description

technical field [0001] The invention relates to the technical field of deep-sea oil detection structures, in particular to an anti-falling connection structure of a deep-sea oil detector. Background technique [0002] In the process of oil well logging, it is necessary to pass the detector into the well for detection. Since the cable will generate left and right uncertain torque during the up and down process, the connection end will be loosened during the left and right back and forth process, which will make the instrument and The connection head falls off, causing liquid to enter the instrument, thereby affecting the normal operation of the instrument. Contents of the invention [0003] The purpose of the present invention is to provide an anti-falling connection structure of a deep-sea oil detector to solve the problem that the torsion force proposed in the above background technology will cause the instrument and the connector to fall off, causing liquid to enter the ...
