Problems solved by technology

[0003] The service conditions of the drill pipe are harsh during the drilling process. Failures often occur in the system, seriously affecting the drilling schedule and increasing the cost of drilling
Moreover, the existing drill pipes are basically international standard drill pipes. However, the parameters of the actual drilling site are different, and the requirements for the drill pipes are different. The same standard drill pipe cannot meet the needs of all terrains or underground environments. Therefore, there is an urgent need for a drill pipe designed according to actual drilling data, which ensures the passage of drilling fluid and the safety of drilling.

Abstract

The invention provides a petroleum drill rod. Various underground parameters are estimated according to adjacent well data of a site needing to be drilled, and comprise the inner diameter, the outer diameter, the annulus pressure and the internal pressure of the drill rod preset according to the adjacent well parameters and geological detecting parameters; and then, the drill rod is designed through calculating formulas, so that the designed drill rod is more accordant with the scene demands, the safety of the scene operation is guaranteed, and the personal safety of petroleum workers is further guaranteed.

Description

technical field [0001] The invention belongs to oil drilling, and mainly relates to an oil drilling rod. Background technique [0002] The drill pipe is the main component of the drill string, which transmits torque during rotary drilling, serves as a circulation channel for drilling fluid during the drilling process, and lengthens the drill string through continuous connection to achieve the purpose of continuously deepening the wellbore. Drill pipe plays a very important role in drilling equipment, and its service life has a crucial impact on drilling speed and quality. The drilling process is a key link in the exploration and development of oil and gas. Its technology and level directly affect the quality and benefits of oil and gas exploration and development, and its cost accounts for more than 50% of the total investment in exploration and development. important role. [0003] The service conditions of the drill pipe are harsh during the drilling process. Failures o...
