摘 要:当油田进入二次开发阶段,含水量日渐增多,给开采带来了更高的难度,油田开发已逐渐由厚油层向薄油层挖潜,从主力层向非主力层转向,不停井分层测压技术不但能够精确的计算出当前地层的表皮阻力、泡点压力及地层渗透率等参数,用以辨别油组之间的厚度及油层的连通性,判断是否分布稳定的隔层使之构成独立的压力、油水系统,从而为小层、单层划分提供依据,为下步低、特低渗透中、高含水油藏“二三结合”治理做好技术支撑。本文摘要主要介绍在生产状态下实现测分层压力的工艺技术,并着重阐述了该工艺技术的原理与特点,结合现场测试情况说明了工艺技术的方法与难点,并对几点经验认识进行了探讨。When the oilfield into the secondary development stage,the water content is increasing,brings the higher difficulty to exploitation,oil field development has gradually from thick oil layer to thin oil layer tapping,from the main layer to the main layer,keep well layered pressure measuring technology not only can accurately calculate the current formation of skin resistance,bubble point pressure and formation permeability parameters,used to identify the thickness of the oil group and the connectivity of oil layer,to determine whether the distribution of stable layer form an independent pressure,oil and water system,to provide the basis for small,low permeability,high water content reservoir"two or three combination"control provide technical support.This paper mainly introduces the technology of measuring stratified pressure in the production state,and mainly expounds the principle and characteristics of the technology,explains the method and difficulty of the technology combined with the field test,and discusses some experiences.
