Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] as attached figure 1 , figure 2 As shown, the logging sky pulley suspension device includes a ring body 1 with a ring-shaped center, and the outer contour of the upper end of the ring body 1 is a ring shape, and the upper ring part is used for hooking with the hook of the logging derrick , the lower end is a square shape, the horizontal part of the bottom of the square shape is used as the contact surface with drilling and workover, and it is the main load-bearing contact surface during well logging, which plays the role of fixing and hanging. Covering the two mounting methods widely used in well logging sites at present; the lower end of the ring body 1 is connected to the step 2, the step 2 is an electric elevator trigger mechanism, the lower end of the step 2 is connected to the connecting rod 3, and the lower end of the connecting rod 3 is connected to accept ...

Abstract

The invention relates to a logging top sheave suspension device. The problems that the existing top sheave uses a wire rope sleeve connection method and rubs with a wellhead when a logging cable is lifted and pulled down, so that the cable is easy to damage and unsafe factors are caused are solved. The device is characterized in that the outer contour of the upper end of a circular ring body (1) is in a circular shape, and the lower end is in a cube shape; a step (2) is connected to the lower end of the circular ring body (1), a connecting rod (3) is connected to the lower end of the step (2),and a receiving ring (4) is connected to the lower end of the connecting rod (3). According to the logging top sheave suspension device, cable damages in the engineering logging process can be reduced, and the safety and reliability of a top heave suspension system during the logging construction process are increased.

Description

technical field [0001] The invention relates to the technical field of oil field logging engineering, in particular to a logging sky pulley suspension device. Background technique [0002] Installing the sky pulley in the well logging process is an essential step. In the past, the sky pulley was connected to the elevator of the operation frame, the drilling rig or the crane of the derrick truck through a combination of a wire rope sleeve and a U-shaped hook. hook position. There is a certain distance between the sky pulley and the elevator of the work frame, and there is a certain angle between the ground pulley and the sky pulley, which will cause the sky pulley to deflect, causing the logging cable to rub against the wellhead and damage the cable. When the engineering cutting logging or the logging instrument is blocked or stuck, since the connection mode of the sky pulley is a soft connection, the sky pulley will vibrate greatly, which will easily lead to the cable jumpi...
