中文摘要

      以往的冲击式钻井是凭人的感觉来判断钻具在井下的工作状况，容易失误而引发事故。所研制的微机控制冲击式钻机操作指导系统利用模糊控制原理，能对钻具的正常、绳松和空顿三种状态作出及时准确的判断，并指导司钻作相应的提绳和给进操作。还能对断钻头、断绳和卡钻三种故障进行检测和报警。

英文摘要

      In the past, an operator judged working state of a drilling tool in an oil well by his sense. It was often misjudged and caused accidents. The operation guide system for precession drill which works on the basis of fuzzy control theory can decide accurately and timely three kinds of working state: a normal one, a slack steel rope and a tight steel rope. On the basis of above judgement, this system can also discover three kinds of accidents: the drilling head break, the steel rope break and drilling tool blocked.
