Description

Technical Field

[0001] The invention relates to the technical field of oil drilling, and in particular to a safe oil drilling and production equipment. Background Art

[0002] Petroleum is a fluid mineral buried deep underground. Initially, people called the oily liquid minerals produced in nature petroleum, the combustible gas natural gas, and the solid flammable oil minerals asphalt. With the in-depth study of these minerals, people realized that they are all hydrocarbon compounds in composition and are related to each other in origin, so they are collectively called petroleum; petroleum extraction technology includes well logging engineering, drilling engineering, oil production engineering and oil and gas gathering and transportation engineering.

[0003] After searching, it is found that the early stage of oil extraction needs to reach the oil layer through drilling, and then negative pressure extraction is performed, and then a series of processing is performed on the crude oil for people to process and use. When drilling for oil, one end of the drill bit needs to be extended to the deep crust. The existing drill bit can drill smoothly directly under the action of a large thrust, but the soil brought out will be continuously accumulated near the drill mouth, which is very unfavorable for the auxiliary construction at the wellhead; based on this, we propose a new type of drilling equipment that can quickly discharge the soil generated during drilling, so as to ensure that the situation near the wellhead is not so complicated when installing the rod or when an unexpected situation occurs, which is conducive to the rapid construction of the wellhead inner wall reinforcement project in the later stage.
