摘要
锦99块杜家台油藏为注水开发的普通稠油油藏,其构造复杂,断层发育,断块多,储层物性较好,但非均质性强。于1993年底进入高含水期开发阶段,含水上升速度快,储量控制程度低,油井稳产基础差。通过加强地质研究,深入油藏开发分析,充分利用油藏动态监测技术指导高含水区剩余油分布规律的研究。主要开展了吸水剖面、地化录井、中子寿命测井、井间示踪等技术,加强了动态监测,利用动态监测结果指导水淹规律及剩余油分布规律的研究,确定挖潜上产的有利区域。根据动态监测成果,针对开发中主要矛盾,在开发中实施了一系列措施,取得了显著的效果:对油井实施堵水作业,实现了降水增油;对注水井进行调整,提高了注水利用率。这对于其他同类油藏高含水期开发具有一定的借鉴作用。
Jin 99 Dujiatai reservoir is the water flooding heavy oil reservoir with the edge and bottom water and complex faults,blocks as well as better reservoir properties,but the heterogeneity is strong.In the end of 1993,Jin 99 Dujiatai reservoir was at high water cut stage,and low level of reserves control.Based on analysis of reservoir development,and full use of performance reservoir monitoring technology,the distribution of the remaining oil is researched.The main jobs are the logging,neutron lifetime logging and inter-well tracer technology.According to the result of dynamic monitoring,in view of the main issues,a series of measures are implemented and good result is achieved.Water shutoff is taken,water-producing rate and oil recovery are decreased and enhanced respectively,water injectors are adjusted and applying efficiency of injected water is improved,which is a meaningful reference for the production of the high water cut reservoirs.
