Petroleum geological drilling rock debris cleaning device

Abstract

The invention discloses a petroleum geological drilling rock debris cleaning device and relates to the technical field of petroleum geological drilling. The petroleum geological drilling rock debris cleaning device comprises a rack, a stirring barrel, a stirring device, a motor and a water suction pump; the stirring barrel is arranged on the inner side of the rack; a feeding port is formed in one side of the top of the stirring barrel; a discharging port is formed in the bottom of the stirring barrel; the stirring device is arranged in the stirring barrel; the stirring device comprises a power rod, a stirring shaft and stirring blades; the stirring blades are fixed on the power rod through the stirring shaft; the power rod is a hollow pipe with upper and lower openings; the top end of the power rod is connected with the water suction pump through a water inlet pipe; a water outlet hole is formed in the bottom end of the power rod, and the water suction pump supplies water into the stirring barrel through the water inlet pipe and the power rod; and the power rod is driven by the motor to rotate to drive the stirring blades to rotate. The petroleum geological drilling rock debris cleaning device can achieve automatic cleaning of rock debris, and has the advantages of being good in rock debris cleaning effect, capable of saving labor and time, efficient and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of petroleum geological drilling, in particular to a cuttings cleaning device for petroleum geological drilling. Background technique [0002] Petroleum geological drilling refers to selecting the most favorable drilling location for oil and gas accumulation after geological survey and geophysical exploration, and using drilling technology to drill through oil and gas layers, so as to test geophysical data, understand downhole oil and gas geological exploration data, and calculate oil and gas reserves. Drilling projects for the purpose of providing development prospects, referred to as oil and gas drilling. At present, this technology is also widely used in the construction of unconventional shale gas, coalbed methane, tight sandstone gas and other projects. Since the diameter of this type of well is relatively large (generally the final hole is 215.9mm) and the well is relatively deep (mostly 1000-7000m), ...

AI Technical Summary

Problems solved by technology

[0007] First, the cleaning is not thorough

When the equipment is working, because of the quality difference between cuttings and water, the cuttings can only move in a circular motion following the stirring teeth at the bottom of the mixing bucket. The cuttings and water cannot mix with each other, and thorough cleaning cannot be achieved.

Second, new and old cuttings are easy to confuse

When dumping the cuttings in the mixing tank, under the action of water and impurities, the cuttings are easy to stick to the wall and cannot be dumped cleanly. The old cuttings that cannot be poured out are confused with the new cuttings added later, which makes the lithology identification and judgment not allowed
