| 摘 要： | 油气圈闭勘探以追求最小投入和最大利润为目的。针对在油气圈闭进行组合优化决策时缺少严格风险分析和经济效益评价问题，根据运筹学中最优化理论，在对圈闭进行合理地质储量计算和严格风险分析的基础上，建立了油气圈闭勘探风险与获取地质储量的组合优化模型，实现在满足特定约束条件达到效用最高，使整个圈闭勘探在风险与收益间达到平衡。即在一定风险范围内，获得圈闭组合的地质储量最大；在地质储量一定时，圈闭组合的风险最小。对东营凹陷等地区储备圈闭中的检测结果表明，该方法算法可靠，操作性较强，能为油气圈闭勘探决策提供科学的依据。

| Abstract: | The objective of hydrocarbon traps exploration is hankering for maximum profit. To optimize making decision for the hydrocarbon traps, and in order to enhance the strict risk analysis and the economic beneficial evaluation, according to the optimized theory in the operations research, the paper sets up the optimal combination models of hydrocarbon-traps exploring risk and obtaining geological reserves on the basis of calculating geological reserves reasonably and analyzing risk strictly. It can come true and make active the maximal effectiveness in satisfying special restrained conditions, and make the whole trap explorations achieve equilibrium between risking and incoming. That is to say, firstly, reaching maximal geological reserves of trap combinations in the definite rage of risk, secondly, reaching minimum risk of trap combinations in the definite rage of geological reserves. When this method was applied in the Dongying depression reserve traps, for dependable and apt to operate, it can supply more scientific foundations for the exploration decision about hydrocarbon traps. |
