The tri-stack system of the reservoir in the Lepidium meyenii has the advantages of locally developing a 'dessert' reservoir, complicating reservoir lithology, developing gravels, poor drillability and strong heterogeneity, and bringing certain difficulty to the acceleration of drilling tools.
Because the horizontal section of the horizontal well in the area is long, the control points of the horizontal section are more, the track of the borehole is complex, the friction resistance and the torque of a tubular column and a borehole wall in the well are greatly increased, the drill column is subjected to buckling deformation, once the spiral critical buckling force of the drill column is exceeded, the drill column is self-locked, so that the weight on bit cannot be effectively transmitted, and finally the horizontal section is difficult to extend and drill. Meanwhile, the retention time of the rock scraps in the horizontal well is long, the rock scraps are easy to deposit on the lower edge of the well hole to form a rock scraps bed, the rock scraps are seriously accumulated at the near-bit end to generate pressure supporting and friction torque increasing, so that the mechanical drilling speed is greatly reduced, and meanwhile, underground risks such as sand setting and drilling sticking are easy to cause. Along with the extension of the horizontal well section, the hydraulic pressure consumption required for removing rock debris is increased sharply, and the fluctuation of the pressure has a great influence on the stability of the well wall. Because of the above problems, there is a need to develop related technical researches to solve the development problems.

In the drilling process, after the sensor assembly is arranged in the outer pipe body and underground information is collected, the underground information is transmitted to the intelligent controller 19 of the intelligent control mechanism in real time, after the intelligent controller 19 receives the feedback information of the sensor assembly, the ball valve 18 is dynamically regulated and controlled to rotate to a proper angle through a preset program, so that self-adaptive regulation is performed, the flow is conveniently modulated, the pulse frequency and the impact frequency are further changed, rock is assisted to be broken, meanwhile, the lower part of the impact rod 10 can be directly connected with a drill bit, and the drill bit is assisted to break rock through modulating pulse jet flow and axial vibration impact; the drilling device can also be connected with a downhole tool, drilling friction is reduced through vibration, the drilling period is shortened, and the cost and efficiency are reduced.
The foregoing is merely exemplary of the present application and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the scope of the present invention should be included in the protection scope of the present invention.
