Description

Technical Field

[0001] The utility model relates to the technical field of well logging tools, in particular to a novel fast cable hanger. Background Art

[0002] Well logging is to send the logging instrument and the cable downhole. During the logging operation, if abnormal phenomena such as well kick or overflow are found, the logging must be stopped quickly, and the blowout prevention unit must be switched to lower the drill bit to kill the well or shut down the well, so as to restore the control of the wellbore and prevent the occurrence of blowout accidents. However, during the logging operation, there is a cable at the wellhead, and it is impossible to directly drill or shut down the well. In order to ensure the safety of well control, there is not enough time to take out the instrument in the well, so the cable must be cut off before lowering the drill bit. However, directly cutting the cable will cause the instrument to fall into the well, resulting in difficulties in subsequent processing operations and economic losses. Utility Model Content

At this time, the locking cap 4 is pressed on the left clamping plate 1 and the right clamping plate 2, and the left clamping plate 1 and the right clamping plate 2 cooperate with the clamping hole 5 of the hanger 3 through the conical surface, so that the left clamping plate 1 and the right clamping plate 2 clamp the cable. In the embodiment, the locking cap 4 is connected to the hanger 3 by threads; after the hanging part completes the clamping of the cable, a support piece that can hold the hanger 3 is pre-set at the wellhead of the drilling well, and then the cable on the upper part of the locking cap 4 is cut off, the hanger 3 is first supported by the support piece, and then the joint 7 is inserted from the upper side of the hanger 3, and the hanger 3 pushes open the hook 9 on the connecting seat 8 until the hook 9 is stuck in the groove 10 on the side wall of the hanger 3, completing the connection between the connecting part and the hanging part, and then the blowout prevention drilling tool is connected to the upper end of the joint 7, and the support piece at the wellhead is removed, and the whole can be lowered into the well for blowout prevention work, without taking out the logging instrument and the cable, speeding up the operation of preventing blowout accidents; after use, the drilling tool can be lifted up, and it can be taken out together with the cable and the instrument, avoiding the difficulty of taking out the cable and the instrument from falling into the well, and avoiding economic losses;

[0020] Preferably, an elastic member 11 tending to force the connection seat 8 to move downward is provided at the inner upper end of the joint 7, and a support ring 12 for supporting the connection seat 8 is provided at the bottom of the joint 7, and the inner diameter of the support ring 12 is larger than the outer diameter of the upper end of the hanging seat 3; in this embodiment, the elastic member 11 is a spring, and there is space for the connection seat 8 to move upward in the joint 7. In this embodiment, the spring can produce a buffering effect during the lowering process in the well;

[0021] Preferably, the connecting seat 8 includes a semicircular left ferrule 13 and a right ferrule 14, the left ferrule 13 and the right ferrule 14 are connected by bolts, and the connecting seat 8 is detachable from the left and right sides. After the cable and the instrument are taken out, the connecting seat 8 is taken out of the connector 7, and the left ferrule 13 and the right ferrule 14 can be separated from the left and right sides to facilitate the separation from the hanging seat 3;

[0022] Preferably, a positioning block 15 is provided on the left ferrule 13, and a positioning hole 16 is provided on the right ferrule 14 to cooperate with the positioning block 15, and the left ferrule 13 and the right ferrule 14 are positioned by the cooperation of the positioning block 15 and the positioning hole 16;
