Problems solved by technology

[0003] At present, the balance nipple with a diameter of about 120mm is more common in the market, and the maintenance and maintenance of the nipple is relatively complicated. In the logging operation below the 5-inch drill bit (127mm), it is often not possible due to the limitation of the outer diameter of the tool. Complete the logging operation

Abstract

The invention discloses a disassembling and assembling hydraulic balancing system short section. The disassembling and assembling hydraulic balancing system short section comprises a long-strip-shaped main basic body; and a front connecting head and a rear connecting head are arranged on the head and the tail of the main basic body correspondingly, and a motor power part is arranged in the middle of the main basic body. The disassembling and assembling hydraulic balancing system short section is characterized in that a fixing notch is formed in the side wall of the main basic body, and a detachable mud collecting assembly is arranged in the fixing notch. The mud collecting assembly comprises a hollow long-strip-shaped slurry barrel, and a piston device used for extracting slurry is arranged in the slurry barrel and driven by the motor power part. Maintenance time is greatly shortened due to adoption of the detachable mud collecting assembly, and the short section is particularly suitable for well logging operation on small-sized (a drill bit of 127 mm or below) boreholes.

Description

technical field [0001] The invention relates to an oil exploration device, more precisely, a detachable short joint of a hydraulic balance system. Background technique [0002] In the process of oil exploration, it is necessary to use formation fluid sampling tools to take formation fluid samples, so as to accurately determine the position of the oil layer, so as to facilitate the extraction of oil. The sampling process of the formation fluid sampling tool is realized by a hydraulic power device installed on it and driving the valve body inside the whole device to conduct and close. [0003] At present, the balance nipple with a diameter of about 120mm is more common in the market, and the maintenance and maintenance of the nipple is relatively complicated. In the logging operation below the 5-inch drill bit (127mm), it is often not possible due to the limitation of the outer diameter of the instrument. Complete logging operations.
