【摘要】 在适当的假设条件之下,建立了盘式单牙轮钻头破岩机理仿真模型,并在此基础上开发出盘式单牙轮钻头破岩机理仿真软件。通过将仿真模型的计算结果与西南石油学院钻头研究室部分台架实验结果进行对比,验证了该仿真模型的正确性。完成了不同钻井参数、不同钻头结构和不同岩石性能等条件下盘式单牙轮钻头破岩机理仿真分析,为盘式单牙轮钻头的设计提供了理论依据。更多还原

【Abstract】 This paper established the model of rockbreaking mechanism on disc onecone bit, and developed the simulate software. Compared the result of the simulate model with the experimental data that collected by the Lab. of Drilling Bit in Southwest Petroleum Institute, the model has been validated. With the simulate program, the simulate study on rockbreaking mechanism of disc onecone bit had been done in different conditions such as different drilling parameters, different bit structure, different rock performance and so on, which was the theoretic reference to the design of disc onecone bit.更多还原
