对局部构造阶段性勘探决策方法的探讨

AN APPROACH TO THE DECISION METHOD OF STEPWISE EXPLORATION FOR LOCAL TECTONICS

目前流行以决策树方法进行勘探决策 ,但这种方法实际应用起来却比较困难 ,原因在于它在决策时总是要考虑勘探工作的全过程。油气资源勘探工作是分阶段性的 ,每个阶段都有其阶段性的目标。只要油气勘探工作在每个阶段都能以最小的成本最好地实现了每个阶段的工作目标 ,那么油气勘探工作的全过程也就能以最小的成本获得最好的结果。文中提出一种在勘探阶段以最小成本拿最多储量为目标的勘探决策方法。

The decision tree method is frequently used to make exploration decision at present.But the application of this method in practice is not easy because it always considers the whole process of exploration.The exploration of hydrocarbon resources is step by step,and each step has its own targets.Only if hydrocarbon exploration best realizes the targets of each step by the least cost,can the whole process of it obtain the best results by the least cost.In this paper,an exploration decision method aiming at getting the most reserves by the least cost in the exploration stage is suggested.
