Description

Technical Field

[0001] The present invention relates to the technical field of oil well logging loading and unloading, and particularly to a loading and unloading device for firmly grasping oil well logging. Background Technique

[0002] ‌Oil well logging‌ is a technology that uses geophysical principles to measure the physical properties of underground rock formations in order to obtain information related to oil and gas reservoirs. It measures geophysical parameters such as the electrochemical properties, conductivity, acoustic properties, radioactivity, etc. of the formation to identify underground rock formations, such as oil, gas, and water layers. Oil well logging plays an important role in oil and gas field development and drilling engineering. It can not only discover and evaluate oil and gas reservoirs, but also provide detailed information about formation structure, fluid properties, and reservoir permeability; When installing ‌oil well logging‌, it needs to be lifted by a crane. Currently, the general crane fixes the ‌oil well logging‌ through steel ropes. After the crane lifts the ‌oil well logging‌ to the installation location via the steel ropes, since the steel ropes do not have the ability to adjust the direction, when it is necessary to adjust the installation angle of the ‌oil well logging‌, multiple operators need to support the ‌oil well logging‌ and adjust its angle. However, the ‌oil well logging‌ is relatively heavy, and it is very laborious for the operators to adjust its angle, which affects the stability of the ‌oil well logging‌ installation.

[0014] When the clamping plate of the present invention clamps the oil well logging, it will push the limit frame to move inside the round hole rod. When the limit frame moves, it will pull the rectangular frame to move through the force-bearing plate. When the rectangular frame moves, it will pull the stabilizing plate to move closer to each other through the reinforcing plate. When the stabilizing plate moves, it will push the contact pad through the groove rod to squeeze and fix the oil well logging, further improving the stability of the oil well logging after clamping.
