勘探工作量预算是决定勘探资金投入和预测油气圈闭探明储量的主要依据.分析、研究了地质风险与条件概率、压力传播与单井控制面积的关系.在多元判别的基础上,提出了两种用于预算合理探井投入量的方法,即条件概率法和单井控制面积???统计判别法,并用这两种方法分别预算了“九五”期间预探井和评价井的工作量.通过稀井广探、少井高效的可行性分析认为:随着勘探的不断深入,探井的面积正在不断提高,评价勘探效果具有上升趋势;预算的单井控制面积比实际钻井单井控制面积大,表明过去对老气藏评价井的投入过多,今后应减少探井数;随着勘探技术及油气藏描述手段的不断发展,对评价目标圈闭以及含油气性的评价将会愈来愈精细和准确,这对准确预报油气藏,提高探井单井控制面积将会有愈来愈显著的作用.“,”To budget the amount of exploration works is the principal basis of deciding investment and predicting oil and gas proved reserves.Through analyzing and studying the relation of geological risk with the conditional probability,pressure propagation and single wellcontrolled area,on the basis of multivariate discriminant analysis,two methods used for budgeting a reasonable amount of exploration wells,i.e.the conditional probability method and single wellcontro...
