Research On Measurement Scheme Of Drilling And Torque Engineering Parameters

With the development of oil drilling technology,the real-time and accuracy requirements of underground engineering parameters are also getting higher and higher.The drilling and drilling technology is more and more widely used in different areas and different well types.The engineering parameters have important guiding effect on the drilling process.At present,the domestic drilling and drilling equipment can not solve the coupling effect of the drilling and torque measurement,and propose a measure to solve the coupling between the drilling pressure,the torque and the influencing factors Program has practical significance.Based on the measurement of the short section in the sidewall opening,this paper presents a measurement method of cylindrical sidewall opening,analyzes the measurement circuit of the drilling pressure and torque in the measurement scheme,and establishes the strain and output according to the strain test method The relationship between the voltage and the voltage is calculated.The numerical model is used to establish the short section model,and the stress state of the short section is analyzed.The ideal model of the pressure and torque is calculated.Considering the coupling effect of the pressure and torque,When the drilling fluid pressure,temperature and bending moment,the drilling pressure,torque measurement program to amend,put forward the corresponding correction formula.In this paper,the measurement scheme of drilling and torque engineering parameters of cylindrical sidewall hole is determined by numerical simulation.A short section structure which can realize the analysis of the bit pressure and torque decoupling is proposed,which provides the design and research for the short section of the drill A certain theoretical basis.
