Problems solved by technology

At present, more and more wells are drilled with rotary percussion drilling technology, but the existing technology does not take into account the difference in rock breaking efficiency caused by the change of the axial mode shape of the drill bit, and lacks the basis for adjustment of drilling control parameters , which in turn affects the rock-breaking efficiency of rotary percussion drilling

Abstract

The object of the present invention is to provide a drilling control method, device, electronic equipment and storage medium, the control parameters of the drilling include the excitation frequency of the exciter, the excitation amplitude of the exciter, the method includes: according to the first A control parameter to obtain an initial mode shape; when the initial mode shape conforms to the rules of the target mode shape, determine the contact time; wherein, the target mode shape includes a one-period collision mode shape; according to the rock stiffness and the described The correlation characteristic of the contact time determines the rock stiffness data; according to the rock stiffness data, the adjustment interval of the second control parameter is determined; the second control parameter is used to characterize the corrected control parameter. In order to obtain optimized drilling control parameters, maintain and extend high rotary rock breaking efficiency, and avoid internal consumption of energy.

Description

technical field [0001] The invention relates to the field of petroleum drilling, in particular to a drilling control method, device, electronic equipment and storage medium. Background technique [0002] For the research on rotary percussion drilling technology, researchers have tried different excitation energy supply methods and different excitation control methods to improve rock breaking efficiency. American Petroleum Corporation has considered the use of air hammer to realize rotary percussion drilling, and conducted field tests. Researchers at Newcastle University in the United Kingdom considered using compressed air and hydraulic pistons to impact the drill pipe, converting the potential energy of air and water into kinetic energy and transmitting it to the drill bit for rock breaking. Australia's CSIRO Institute designed self-excited axial vibration drilling tools to improve rock breaking efficiency. The University of Aberdeen in the United Kingdom carried out rese...
