模糊评判方法在圈闭地质评价中的应用

介绍了应用模糊数学综合评判方法评价圈闭含油气的可能性。用模糊数学综合评判方法评价圈闭,考虑了不同地质因素对圈闭含油气性的不同影响,并根据地质家的经验和地质过程对圈闭含油气性的影响程度赋予不同地质因素不同的权重,使圈闭地质评价定量化,能及时、迅速地为勘探规划部署指明方向,并提供较准确的目标。华北油田2001年的油气勘探实践证明,方法是科学的、合理的、可行的、经济的。

THE APPLICATION OF THE FUZZY JUDGMENT METHOD IN THE GEOLOGICAL EVALUATION OF TRAP

The article deals with a way to evaluate the possibility of trapped oil and gas by making use of the fuzzy judgment method. When a trap is assessed by way of the fuzzy judgment, the result of the geological evaluation of trap is quantified, for that the different geological factors have a different effect on the possibility of trapped oil and gas is taken into account. The way, therefore, can give exploration, plan, arrangement directions timely and rapidly and provide the more accurate goals. In 2001,the practice of the Huabei oil field proved that the way is scientific, reasonable, feasible, economical.
