Comprehensive experimental device for drilling through casing and rock with particle jet and drill bit

Abstract

The invention belongs to the field of petroleum drilling and oil extraction and particularly relates to a particle jet flow and drill bit united casing pipe and rock drilling comprehensive experimental device. The comprehensive experimental device comprises a high-pressure pipeline, a hydraulic control rod, an electric lead screw, a drilling rod, a torque sensor, a rock, a casing pipe, a drill bit, a computer, a hydraulic control valve group, a guiding seat, a particle jet flow nozzle, a datum collector, a hydraulic working station, a load sensor, hydraulic jack, a speed-adjusting motor, a power transmitting assembly, a rotary speed sensor, a linear sensor and the like. The comprehensive experimental device can simulate drill bit rotating and adjust the rotary speed, the drilling pressure is exerted, and the size of the drilling pressure is adjusted; the drilling angle of the drilling bit is adjusted, and the rotary speed, the drilling pressure, the torque and the footage parameters of the drill bit are measured, stored and displayed in real time; the on-scene condition is well stimulated, hydraulic control and electric control are combined, the automatic degree and the integrated degree are high, the structure is reasonable, using is safe and reliable, and through an experiment, the particle jet flow and drill bit mechanical united casing pipe and rock drilling optimized parameters can be provided for on-scene construction.

Description

technical field [0001] The invention relates to a comprehensive experimental device for drilling through casing and rock jointly by a particle jet and a drill bit, which belongs to the field of petroleum drilling and oil production. Background technique [0002] With the continuous development of oil and gas resources, more and more problems are faced in the process of oil and gas exploitation, such as declining oil well production, serious water flooding, casing damage, frequent downhole accidents, etc., and high water cut wells, The number of "old wells" and "dead wells" such as engineering abandoned wells is increasing, which greatly affects the efficient exploitation of oil and gas resources. Many problematic wells and abandoned wells still have high mining value. If they are effectively Secondary development will effectively increase the output of oilfields and alleviate the shortage of resources in my country to a large extent. Moreover, under the current low oil price s...

Problems solved by technology

At present, the number of casing sidetracking wells in my country is increasing, but the efficiency and reliability of sidetracking are low, and it is difficult to realize rapid sidetracking and window opening, and the cost of sidetracking is also high. Therefore, it is urgent to develop a fast casing The new technology of pipe window sidetracking can fully excavate the remaining oil and gas resources in deep formations
