油气藏的数学评判及其富集区的预测

TNE MATHEMATIGAL EVALUATION FOR PETROLEUM AND GAS DEPOSIT AND THE CALCULATION OF THE AREAS WITH RICH PETROLEUM AND GAS DEPOSIT

采用数量化理论、Fuzzy数学方法与判别分析法对油气井的产气状况和地震、地质信息进行了分析与评价,找出了地震信息与油气状况的内在联系。其结果已用于对四川某油气田一批井的油气藏的预测和井位选择。

With sevaral mathematical methods such as the theory of quantification,Fuzzy mathematics and analytical evaluation,this paper,providing its analysis and evaluation of the gas production situation,and the earthquake and geological data,descovered the internal relations between earthquake information, petroleum and gas deposit codition. The result above, when applied to calculaton of the petroleum and gas deposit in several oil wells of an oil field in Sichuan,produced a satisfactory effect.
