Flushing and cleaning device for petroleum fracturing acidizing fluid spraying box body and pipe column

Abstract

The invention provides a flushing and cleaning device for a petroleum fracturing acidizing fluid spraying box body and a pipe column, which comprises a supporting bottom frame, a supporting plate, a driven roller, a driving roller, a slow pipe column interior cleaning pipe assembly, a flushing type box body and pipe column outer surface flushing pipe assembly, a hot air wiping guide pipe assembly, a dredging frame assembly, a driving motor, a driving belt and a longitudinal anti-skid shielding plate, the supporting plates are connected to the four corners of the lower portion of the supporting bottom frame through bolts, and the supporting plates are connected to the four corners of the lower portion of the supporting bottom frame through bolts. According to the cleaning device, the outer surface and the inner surface of the petroleum fracturing acidizing fluid spraying pipe column can be washed and cleaned at the same time, the surface of the petroleum fracturing acidizing fluid spraying box body can be washed, operation is easy and convenient, meanwhile, hot air drying and wiping can be conducted on the washed pipe column, and water stain residues are avoided.

Description

technical field [0001] The invention belongs to the technical field of petroleum acidification auxiliary equipment, and in particular relates to a flushing and cleaning device for petroleum fracturing acidification fluid injection box and pipe column. Background technique [0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons in natural occurrence. Petroleum is divided into crude oil, natural gas, natural gas liquid and natural tar, etc. Crude oil is oil that is mined in rock formations and extracted. Fracturing and acidizing is referred to as acid fracturing. The acid liquid is used as the fracturing fluid under the pressure higher than the fracture pressure of the formation, and the fracturing without proppant is carried out. During the acid fracturing process, the wall surface of the crack is eroded into an uneven surface by the dissolution of the acid liquid, so that the wall surface of the crack will not be completely closed after the pump is...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a flushing and cleaning device for the oil fracturing acidizing fluid injection box and the pipe string, so as to solve the problem that the cleaning tools of the existing oil fracturing acidizing fluid injection equipment are not convenient for cleaning the inner parts of the pipe string. The outer wall is cleaned at the same time, it is not convenient to dry the cleaned pipe string in time and the cleaning function is relatively simple
