【摘要】：反循环钻井过程中,压缩气体沿双壁钻杆环状间隙进入井底,在井底借助反循环钻头抽吸作用形成反循环流场,而后携带岩屑沿中心通道上返至地面。根据气体反循环钻井工作原理和钻井工具结构特征,研制了气体反循环钻井井底流场模拟实验装置,该型实验装置能够模拟反循环钻井中井底流体的运动过程,并能对井底反循环效果进行验证和评价。反循环实验器教学装置的研制完善了气体反循环钻井技术的实验教学环节,同时激发学生们深入研究反循环钻具结构的兴趣。
[Abstract]:During reverse circulation drilling, the compressed gas enters the bottom hole along the annular clearance of the double-wall drill pipe, and the reverse circulation flow field is formed at the bottom hole by the suction action of the reverse circulation bit. Then the cuttings are carried back to the ground along the central passage. According to the working principle of gas reverse circulation drilling and the structural characteristics of drilling tools, a simulation experiment device for bottom hole flow field of gas reverse circulation drilling is developed. This type of experimental device can simulate the movement process of bottom hole fluid in reverse circulation drilling. And it can verify and evaluate the effect of reverse circulation at the bottom of the well. The development of the teaching device of the reverse circulation experiment has improved the experimental teaching link of the gas reverse circulation drilling technology. At the same time, it arouses students' interest in further studying the structure of reverse circulation drilling tools.

【正文快照】： 0引言随着勘探的不断深入,常规石油天然气资源增储增产难度越来越大,非常规油气资源的战略地位日趋重要[1-3]。与此同时,对油气勘探技术的要求也不断提高,新工艺正在冲击和淘汰着传统工艺[4-7]。特别是在非常规油气资源钻探中,气体反循环钻井工艺有取代正循环钻井工艺之趋势[8
