印尼N油气田油气藏滚动勘探开发技术评述
|
摘要
N油气田属于中等孔隙度与低-中等渗透率多套层系、多断块、复杂断背斜构造砂岩油气藏。复杂的地质特征、构造背景和储层砂体导致油气藏勘探开发风险很大,因此,油气藏勘探开发过程中采用滚动勘探开发模式进行勘探开发。基于滚动开发过程中不断更新、扩充的地震、测井、测试、生产等资料,以地质油藏多学科综合一体化为研究思路,综合利用三维地震构造精细解释技术、井间储层预测技术、测井解释划分油气水分布技术、相控随机建模技术和油藏数值模拟技术,成功的扩大了N油气田储量规模,获得了新增产量,顺利指导了N油气田开发方案设计的完成和实施,取得了良好效果。
N Oil and Gas Field belongs to multiple layered sandstone reservoirs with medium porosity and low-medium permeability in the structure setting of multiple fault-blocks and complex fault anticline.The complexity of geology characters,reservoir composition and structure setting here lead to high risk for exploration and development of N Oil and Gas Field,so rolling exploration and development process are adopted gradually.Based on the updating and increasing various kinds of data,such as seismic data,logging data,testing data and production data and so on,it integratedly uses geology and reservoir engineering methods comprehensively takes advantage of 3Dseismic structure fine interpretation technology,reservoir prediction technology,the technology of determining fluid distribution by logging interpretation,facies-controlling random model method and reservoir numerical model,the reserves scale is successfully enlarged and new reserves are acquired.It finally leads to the successful design and implement of N Oil and Gas Field POD and good effect is acquired.
