摘要
针对欠平衡空气循环钻井的工况特点,利用可靠性理论分析了常规随钻震击器用于空气循环钻井的失效机理,研发了适用于空气循环钻井的空气随钻震击器。
In view of the working conditions of under-balance-air circulating drilling,failure mechanism of the routine while-drilling jar to the air-circulating drilling is analyzed on the basis of the reliability theory.A air while-drilling jar adaptable to the aircirculating drilling has heen developed.
