北部湾盆地油藏开发类比知识库研究及应用

北部湾盆地油藏开发单元多,类型复杂,开发效果差异大,亟待认清该油田群区域开发规律.建立在油藏分类及阶段划分基础上,通过对北部湾区域178个油藏开发单元静、动态多达50多种数据进行统计,建立区域静、动态知识库.在该知识库基础上,采用统计分析方法,得到适用于北部湾盆地不同类型油藏的产能、采收率及分阶段产量预测方法.该成果有效地提高了北部湾盆地油藏开发指标预测精度及效率,为后续油藏的开发调整奠定了基础.

Research and Application of Reservoir Development Analogy Knowledge Bases in Beibu Gulf Basin

In Beibu Gulf Basin, there are many development units, complex types and different development effects. It is urgent to recognize the regional development law of the oilfield group. Based on oil reservoir classification and stage division Through the statistics of more than 50 kinds of static and dynamic data of 178 reservoir development units in Beibu Gulf area, the regional static and dynamic knowledge base is established. On the basis of the knowledge base, a variety of statistical analysis methods are used to obtain the productivity, recovery factor and phased production prediction methods suitable for different types of reservoirs in Beibu Gulf Basin. The results effectively improve the prediction accuracy and ef ficiency of reservoir development index in Beibu Gulf Basin, and lay a foundation for subsequent reservoir development adjustment.
