Anti-collision protection structure with buffering performance for logging instrument

Abstract

The invention discloses an anti-collision protection structure with buffering performance for a logging instrument. The anti-collision protection structure comprises a protective shell and a logging instrument measuring main body, wherein micro hydraulic oil cylinders are mounted on the left side and the right side below the protective shell; a spacer is mounted on one side, far away from the vertical center line of the protective shell, of each micro hydraulic oil cylinder; a connecting pin penetrates through the upper edge of each spacer; an inner sleeve frame is arranged in the protective shell; connecting springs are mounted on the left side and the right side of the inner sleeve frame; the logging instrument measuring main body is positioned in the inner sleeve frame; a connecting sleeve is mounted above the protective shell; a guide rack is arranged in the connecting sleeve; an adjusting gear is mounted on one side of the guide rack; and a connecting block is mounted on the outer wall above the connecting sleeve. The anti-collision protection structure for the logging instrument is provided with the connecting springs, and external force borne by the protective shell can be effectively buffered through the connecting springs, so that a certain buffering distance is formed, and reliable buffering protection can be effectively provided for the logging instrument.

Description

technical field [0001] The invention relates to the technical field of well logging instruments, in particular to an anti-collision protection structure for well logging instruments with buffer performance. Background technique [0002] The logging tool is used in the field of well sinking. It can continuously scan the well wall, and can also scan horizontally at any level to provide technical data such as the vertical section of the wellbore, the horizontal section, the effective section of the wellbore, and the deviation distance of the wellbore. The logging results can be directly displayed on the computer screen or given by the plotter printer, which is flexible and convenient to use. The use of logging instruments can prevent wellbore deviation, reduce construction period, speed up construction progress, ensure project quality, and have obvious indirect economic benefits and very significant social benefits. There are many types of logging tools on the market, includin...
