中国海相探矿权区块定量评价方法

在研究了我国海相油气探矿权区块基本油气地质条件、勘探程度、技术经济条件等要素和特点的基础上,给出了48个评价参数和归一化取值参照表,建立了探矿权区块评价工作流程、评分参数及计算公式。提出对我国海相勘探层探矿权区块评价应该注意:与国外海相碳酸盐岩评价的差别;与国内陆相碎屑岩评价的差别;成藏组合的划分;评价内容的有效性、不确定性和评价参数的可信度;成败经验的总结和勘探程度的研究。

Quantitative Evaluation Method for Exploration Rights of Marine Strata Regions in China

Three aspects of components and characteristics, including fundamental petroleum geological conditions, technological economic conditions,and exploration activity, are studied. 48 parameters and normalization criterion are given,and the WorkFlow Chart of evaluation and keys are built. By operation principle of polygon geometric elements, the geometry and topological relationship among exploration rights of marine strata, geologic units, exploration extent units, joint ventures and contractual joint ventures are investigated and analyzed. By studying Gradual Weighted Permanental (factorial multiplication) mixed operation formula, a method of prospect marine plays mathematical calculating and comprehensive assessment is established,the software platform of mine-right assessment is developed, and 135 marine mine-rights are computed in queue coefficient. New recognitions regained and results are nice in practice. 70% of prospecting blocks in primary hydrocarbon play principally are the best zones,which may be major targets of marine oil-gas exploration in future.
