Problems solved by technology

[0004] In the traditional oil well logging device, the casing is screwed down under the action of the logging device, and the drill bit at the front end will cause excessive temperature if it works for a long time, which will affect the progress of the logging. Therefore, an intermittent lowering method is proposed structure and oil well logging device to solve the above problems

Abstract

The invention relates to an intermittent lowering structure and an oil well logging device, the intermittent lowering structure comprises a mounting frame structure, two guide rods are symmetrically mounted on the mounting frame structure, and a liftable moving table is slidably arranged on the guide rods; the walking assembly is arranged between the moving table and the frame body mechanism, and the walking assembly is used for driving the moving table to ascend or descend in the axial direction of the guide rod; the intermittent output assembly is connected with the walking assembly, and when the intermittent output assembly drives the walking assembly to move intermittently, the moving table ascends or descends intermittently in the axial direction of the guide rod. The intermittent output assembly is arranged between the moving table and the mounting frame structure, the moving table is intermittently and downwards driven, the purpose of intermittent lowering is achieved, the structure is simple, and practicability is high.

Description

technical field [0001] The invention relates to the field of petroleum logging, in particular to an intermittent lowering structure and a petroleum logging device. Background technique [0002] Well logging, also known as geophysical well logging or petroleum well logging, referred to as well logging, is a method of measuring geophysical parameters using the electrochemical properties, electrical conductivity, acoustic properties, radioactivity and other geophysical properties of rock formations, which belongs to applied geophysical methods (Including gravity, magnetic, electric, seismic, logging). During oil drilling, well logging must be carried out after drilling to the designed depth, also known as completion electrical logging, to obtain various petroleum geology and engineering technical data as the original data for well completion and oilfield development. This kind of logging is customarily called open hole logging, and the second series of logging performed after ...
