油气区域勘探研究系统工程

THE RESEARCH SYSTEM PROJECT OF REGIONAL PETROLEUM EXPLORATION

油气区域勘探研究是一项系统工程，包括盆地分析与评价，含油气系统分析与评价，区带和圈闭分析与评价，油气藏描述与评价以及对以上诸过程进行动态管理的资源序列研究，盆地分析包括地层发育史，构造发展史，沉积演化史和热史，盆地评价的主要内容是烃源岩，含油气系统研究内容主要是烃源岩，含油气系统研究内容主要包括烃源岩，储层，盖层和上覆层等4项静态要素，以及油气生成与运聚的过程，其关键问题是生烃凹陷的生烃量和圈闭的聚集量，区带分析是对有成因关系的圈闭带进行分析，圈闭分析与评价包括地质分析，工程地质分析和经济评价，油气藏描述是对油气田的构造，储层岩性和物性，油气分布等进行描述与评价，贯穿圈闭预探到探明油气田的全过程，资源充列包括推测资源量，潜在资源量，预测储量，控制储量和探明储量的计算以及确定它们之间合理的资源潜力比。

The research of petroleum exploration is a system project. It consists of basin analysis, petroleum system, play and prospect, reservoir description, resources and reserves series. Basin analysis consists of development of stratigraphy, tectonics and structure, sedimentary and thermal histories. Basin evaluation focus on source rock. Petroleum system is composed of four elements including source rock, reservoir, seal rock and over burden and two processes, the former is petroleum generation process, the latter is migration and accumulation process. The key process is generation intensity and amount for petroleum system. Play is a group of prospects related in genesis. Prospect analysis and evaluation consist of geological analysis, engineering and economical evaluation. Resources system contains the amount of speculative resources, potential sources, predicted reserves ,regulatory and explored reserves. The source potential ratio is the key to balance and keep the whole project of petroleum exploration and development in good state.
