Auxiliary pressurizing device for oil exploitation well drilling

Abstract

The invention discloses an auxiliary pressurizing device for oil exploitation well drilling. The auxiliary pressurizing device comprises a motor, a rope wind-up barrel, a derrick, a steel rope, a pressurizing box, a pressurizing pipe, an auxiliary booster pump, a lubricating device and a stabilizing device. According to the auxiliary pressurizing device, a lubricating device is arranged at the lower end of the rope wind-up barrel, a push block is pulled by a hydraulic rod, the push block drives a movable plate to be slidably mounted at the upper end of a sliding seat through a connecting rod,and therefore an oil outlet plate in an oil outlet tank is in contact with the steel rope, and a lubricating function is achieved. A lubricating agent is added in time, the steel rope is prevented from being abraded, and the stability of the device is improved. The stabilizing device is arranged at the lower end of the pressurizing pipe, the pressurizing pipe is placed at the upper end of a connecting plate and the upper end of an inclined plate, then a fixed rod clamps the pressurizing pipe and penetrates through a screw hole, a fixing block is used for fixing, and the stability of the deviceis improved; and pressure of the pressurizing pipe is prevented from being too high, leakage danger between the booster pump and the pressurizing pipe is avoided, and the pressurizing effect is guaranteed.

Description

technical field [0001] The invention relates to the related field of pressurization devices, in particular to an auxiliary pressurization device for oil drilling. Background technique [0002] In my country, the petroleum industry is a pillar industry directly related to the people's livelihood. Under the background of the rapid development of the market economy, my country's petroleum industry has made great progress. Petroleum plays a very important role in industrial production and people's daily life. At the same time, people's demand for oil is increasing day by day, which puts forward higher requirements for oil exploration and development, and when oil is extracted from the surface, due to the small number of drill collars, the drilling pressure is insufficient, resulting in low drilling efficiency. , Therefore, when drilling, an auxiliary pressurization device is required for pressurized drilling. [0003] During the use of the pressurizing device, the steel rope in t...

[0002] In my country, the petroleum industry is a pillar industry directly related to the people's livelihood. Under the background of the rapid development of the market economy, my country's petroleum industry has made great progress. Petroleum plays a very important role in industrial production and people's daily life. At the same time, people's demand for oil is increasing day by day, which puts forward higher requirements for oil exploration and development, and when oil is extracted from the surface, due to the small number of drill collars, the drilling pressure is insufficient, resulting in low drilling efficiency. , therefore, an auxiliary pressurization device is required for pressurized drilling when drilling

[0003] During the use of the pressurizing device, the steel rope in the pressurizing device needs to be manually lubricated to make the steel rope slide steadily, but this operation is troublesome, and the lubricant cannot be added in time, which makes the steel rope suffer from wear and tear. Aggravate, even make the steel rope scrapped, and the pressure of the pressurized pipe is too high, it is easy to cause leakage between the auxiliary pressurized pump and the pressurized pipe, affecting the effect of pressurization
