【摘要】：杨19区延9油藏2009年9月开始注水开发,压力保持水平52.8%,压力保持水平较低,初期开发技术政策还不明确。研究的目的是通过对该油藏地质规律、渗流规律的研究,利用数值模拟技术,结合油藏动态,对该区开发初期稳产技术政策执行效果进行跟踪评价,进一步制定和完善适合该油藏目前开发阶段的技术政策,提出提高油藏见效程度、降低自然递减的方案,确保油藏持续高效开发。本次研究主要是根据油水井静态、动态、试井、数值模拟等资料,研究油藏开发特征、开发规律、油藏渗流特征、合理的开发技术政策以及提高水驱储量动用程度的技术方法,制定油藏开发调整方案。利用各类化验分析资料,通过岩性、电性、物性、含油性等方面研究储层宏观、微观特征;通过现场资料评价水驱状况,研究渗流特征、开发特征及规律;利用油藏工程,结合油藏动态特征,通过对前期开发效果评价,进一步研究制定出各油藏合理的开发技术政策;通过油藏工程、数值模拟等方法预测油藏不同开发阶段的递减规律、含水上升规律;编制多套方案,进行数值模拟研究,跟踪确定最优的1~2套方案,进行现场实施,最终确定适合于目前开发形势的最终方案与各项开发指标。通过油田开发稳产技术的研究,制定出适合该油藏开发的稳产方案,提高注水开发效果,控制含水上升速度,延长中低含水采油期,为实现油藏稳产奠定良好的基础,确保油田持续高效开发。
[Abstract]:Yang District 19 Yan 9 reservoir water flooding development started in September 2009 to maintain the level of 52.8%, pressure, pressure to maintain a low level, the early development of technology policy is not clear. The purpose of the study is based on the reservoir geological law, research on the seepage law, using numerical simulation technology and combined with the reservoir dynamic effect on the early implementation of the policy development and stable production technology region tracking evaluation, further develop and perfect for the reservoir and the current status of the development of technology policy, put forward to improve the reservoir effect, reduce the natural decline of the scheme, to ensure sustainable and efficient development of reservoirs. This research is mainly based on oil well static, dynamic test, numerical simulation data, study the law of development characteristics, reservoir development the seepage characteristics of reservoir, reasonable development technology and policy and improve water flooding reserves technology level, develop reservoir development scheme. Using various test points Through the analysis of data, lithology, electrical property, physical property, oil-bearing property of reservoir macroscopic and microscopic characteristics; through the field data evaluation of water flooding status, study on the flow characteristics, development characteristics and rules; using reservoir engineering, combining reservoir dynamic characteristics, through the evaluation of the pre development effect, further study and formulate development technology the policy reasonable reservoir; through reservoir engineering, prediction of decline at different development stages of reservoir numerical simulation method, the law of water cut increasing; preparation scheme, numerical simulation is conducted to determine the optimal scheme, 1~2 tracking, on-site implementation, ultimately determine the suitable development situation at present the final design and development indexes. Through the research and development of oilfield stable production technology, develop a stable for the reservoir development scheme, improve water flooding efficiency, control the rising speed of water, low water cut oil production period is prolonged. It will lay a good foundation for the stable production of oil reservoirs and ensure the continuous and efficient development of the oil fields.
