Cable cleaning device for geophysical well logging

Abstract

The invention relates to a cable cleaning device for geophysical well logging. The cable cleaning device for geophysical well logging comprises a supporting body I, a guide structure I, a supporting body II and a sweeping structure; a mounting groove is formed in the top of a supporting plate; the guide structure I is arranged in the mounting groove; the supporting body II is arranged at the top of the supporting body I, an arc-shaped groove is formed in the bottom of the supporting body II; and the sweeping structure comprises an arc-shaped supporting plate, conveying rollers, an annular conveying belt, a brush body and a cleaning structure I, the concave surface of the arc-shaped supporting plate faces the supporting body I, the arc-shaped supporting plate is erected in a slot formed in the top of the supporting body II, the slot communicates with the groove, the conveying rollers are arranged at the two end parts of the supporting plate, the rotating shaft end parts of the conveying rollers are connected with a power structure through a transmission structure, an inner ring of the annular conveying belt is connected to the corresponding concave surface and convex surface of the supporting plate in a sliding manner through a guide structure II, the brush body comprises a sweeping part I and a sweeping part II which are symmetrically distributed along a center line of the conveying belt, and the cleaning structure I is arranged above the conveying belt and is used for washing the brush body. The cable cleaning device for geophysical well logging realizes the effect that protection is carried out on the surface of a cable, improves the sweeping and cleaning effect on the cable, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of cable cleaning, in particular to a geophysical logging cable cleaning device. Background technique [0002] Geophysical logging is referred to as logging for short. In the process of exploration and exploitation of oil, coal and metal ore bodies, various instruments are used to measure the physical parameters of the downhole rock formation and the technical status of the well, analyze the recorded data, and carry out geological and engineering aspects of research. [0003] According to the physical basis of logging methods, there are mainly electrical logging, radioactive logging, acoustic logging, and formation dip logging. In oil and gas field logging, logging data are mainly used for stratigraphic correlation, dividing oil, gas, and water layers; determining important parameters such as porosity, oil saturation, and permeability of reservoirs; , study oil, gas, water dynamics and well conditions, and...

Problems solved by technology

[0004] During the logging process, since the cable has the function of data transmission, the cable must be kept clean. Only by ensuring that the cable is clean can the accuracy of the logging parameters be improved. However, when cleaning the cable, it is always Manual cleaning of cables requires manual scrubbing with a brush, but manual scrubbing is inefficient and labor-intensive

The cable cleaning device provided by the prior art can brush the cable, but part of the mud may adhere to the surface of the cable, so simply cleaning the cable with a brush roller cannot clean the cable.
