| 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. |
