摘要
利用现场录井和声波测井资料,根据等效深度法原理计算地层压力的方法,对中国石化缅甸探区地层压力纵向上的变化规律及成压机制进行综合分析,划分压力系统,为探井或评价井优化井身结构设计和平衡压力钻井及保护油气层提供了可靠的依据,收到了初步的应用效果。
This paper presents a technology,based on the principles used in the equivalent depth method,to calculate formation pressure using in-field acoustic logging data. On this basis,the formation-pressure vertical change rules and pressure-forming mechanism of Myanmar prospecting area are comprehensively analyzed in combination of in-situ logging data; and the pressure system is divided,which provides a reliable basis for optimizing the casing program design and balanced-pressure drilling of both exploration and evaluation wells,and protecting reservoir. This technology has achieved preliminary application results.
