| Fossil resources drive the normal operation of modern industry,oil resources also occupy a large proportion in the world energy system.With the rapid development of China’s economy,oil resources have become the bottleneck that restricting China’s economic development.With the increase in the depth of crude oil mining,more and more hard strata are encountered,and penetration rate has become the decisive factor that directly affects the mining efficiency.In the drilling process of deep well and ultra deep well,the phenomenon of bit slip has become the main reason affecting drilling speed.The emergence of a drilling auxiliary device directly driven by the horizontal torque impactor has solved the problem of bit slip.The horizontal torque percussion tool has been developed by foreign companies and has been commercially commercially available.In order to maintain its monopoly in the industry,foreign companies are still in a state of confidentiality.The research on traditional vertical percussive drilling AIDS has been relatively mature in China.But for the more advanced technology,the research on the horizontal torsion impact device with higher drilling efficiency is still in the exploratory stage.Although domestic research institutes and universities have proposed various solutions for torsional impactor,good experimental data have been obtained in the indoor environment.But the oil drilling industry still has no large-scale commercial case of domestic torsional impactor.The main problems in the field work mainly focus on the poor stability of the horizontal impact module,the short life,the lack of working frequency,and the accidental death in the working process.Based on the viewpoint of nonlinear dynamics in the conservation of energy,the working principle of a self circulating horizontal impact device is presented.The structure model is designed and manufactured and the force analysis is carried out.The motion equation and dynamic model of starting and round trip are established,and the feasibility of the horizontal round trip device is analyzed theoretically.And use the Simulink module in the MATLAB language,the nonlinear force characteristics of displacement and velocity caused by pressure change during horizontal impact are simulated.The experimental data of each stage are obtained by building the corresponding laboratory platform,and the correctness and feasibility of the working principle and the reliability of the horizontal impact device are verified.Through the simulation of various working conditions that may be encountered in the actual working process,the adaptability of the self circulating horizontal impact device is studied and verified.The structure and working principle of the horizontal impact device proposed in this paper are of great theoretical and practical significance to the design and development of the horizontal torque percussion device in China.It is conducive to the design and manufacture of reliable horizontal torsion impact devices. |
