摘要
针对开发井小井眼钻井的特点 ,通过现场试验建立了单因素钻速方程 ;以小井眼钻井作为动态系统 ,建立了机械钻速和钻头磨损理论模型 ;应用多目标优化理论 ,对小井眼钻井参数进行了优化设计。经验证 ,符合率超过 90 % ,平均机械钻速达到或超过同区块常规井的水平。目前 ,此项技术已在大庆油田小井眼钻井中推广应用。
According to the characteristic of slim hole drilling of development wells, a single factor drilling rate equation is constructed through field test The slim hole drilling is used as a dynamic system to construct a theoretical model of mechanic drilling rate and bit wearing The theory of multi object optimization is used to perform an optimized designation of slim hole drilling parameters The coincidence rate is proved to exceed 90%, and the average mechanic drilling rate reaches or exceeds the level of the normal wells in the same block Now this technique is applied in the slim hole drilling in Daqing Oil Field
