以兼容度和差异度作为判断不同圈闭评价方法产生的评价方案优劣的依据,并提出了用于圈闭评价方案优化的方法,即兼容度极大化法和兼容度、差异度极大极小化法.在此基础上,结合传统圈闭评价方法和模型,建立了圈闭评价方案优化系统.与运用某一种方法计算出一组评价值然后排序的传统方法比较,该系统不仅能提供多个评价方案,还能提供从多个备择方案中产生优化方案的科学方法,更符合现代科学决策的要求.该系统已在我国某大油田成功应用. The degree of compatibility and the degree of difference are used as the basis for judging the advantages and disadvantages of the evaluation schemes produced by different trapping evaluation methods and the methods for the optimization of the trapping evaluation schemes are proposed, that is, the compatibility degree maximization method and the compatibility degree are extremely different Minimization method.On this basis, combined with the traditional trapping evaluation methods and models, a trapping evaluation scheme optimization system was established.Compared with the traditional method of calculating a group of evaluation values ​​and then sorting by a certain method, the system not only It can provide multiple evaluation schemes and provide scientific methods to generate optimization schemes from multiple alternative schemes, which is more in line with the requirements of modern scientific decision-making. The system has been successfully applied in a large oilfield in China.
