An intelligent logging tool for coalbed methane detection based on the Internet of Things

Abstract

The invention relates to an intelligent logging instrument for coal bed gas prospecting based on Internet of Things. The intelligent logging instrument comprises a main engine, a winch frame, a winch,a transmission line, a detecting stick, a steady mechanism and a guide line mechanism. According to the intelligent logging instrument for coal bed gas prospecting based on the Internet of Things, when the detecting stick stretches into the downhole to perform a logging work, through starting the steady mechanism, the detecting stick keeps steady as moving down, the detecting stick is prevented from sloshing during in the process of moving down, not only can the damage caused by the collision of the detecting stick to the rock wall be avoided, but also avoid the impact on the detecting stick;and secondly, when the winch is pulling in and out of the transmission line, the transmission line is always kept perpendicular to the axis of the winch by starting the guide line mechanism, so thatjamming of the transmission line can be avoided, thereby improving the effect of the collection, and the normal use of the logging instrument is avoided to be influenced.

Description

technical field [0001] The invention relates to the field of coalbed methane detection equipment, in particular to an intelligent logging instrument for coalbed methane detection based on the Internet of Things. Background technique [0002] The logging instrument is an instrument used in the field of well drilling. It can continuously scan the well wall, and can also perform horizontal scanning on any level, and can provide the vertical section of the wellbore, the horizontal section, the effective section of the wellbore, and the deviation distance of the wellbore. material. At present, logging tools are also widely used in the field of coalbed methane detection. Coalbed methane logging refers to the difference in lithology and physical properties between coalbed methane reservoir (coal seam) and surrounding rock, using natural potential, double lateral (or induction), microelectrode, compensation density, natural gamma ray, acoustic time difference, acoustic wave It is ...

AI Technical Summary

Problems solved by technology

[0003] Existing logging tools still have some deficiencies when performing coalbed methane logging. First, one end of the transmission line of the logging tool is wound on the winch, and the other end is connected to the probe. When the winch rotates and the transmission line is released, the probe However, the probe is prone to shaking during the downward movement, which is not only easy to be damaged due to collision with the rock wall, but also has a certain impact on the detection; secondly, the winch is When the transmission line is retracted, the transmission line will move back and forth along the axis of the winch, which may cause the transmission line to be stuck, which will make the retraction effect not good and affect the normal use of the logging tool
