针对多旋回含油气盆地复杂的地质实际,提出了一种统计法结合类比法计算资源量的圈闭加权法，其中引入了圈闭资源量钻探成功率的概念,使圈闭资源量与区带、盆地资源量的定量计算有机结合,避免了成因法产生的诸多不确定性,能够动态地进行区带及盆地资源评价。应用圈闭加权法计算了塔里木盆地刻度区及满加尔油气系统的资源量，结果表明本方法是一种行之有效的资源评价方法。

Aimed at the complex geology of polycyclic petroliferous basins, a new kind of petroleum resource evaluation method —— trap weighting method is established which integrated the advantages of statistics and analogy methods by employing drilling success ratio of trap resource quantity. The method can calculate the petroleum resources of plays and basins omentarily according to the petroleum exploration practice and avoid so much ncertainty engendered by the genesis method. It is proved effective by the application in the reference sections and Manjiaer petroleum system of Tarim basin and has played an important role in the oil and gas resource evaluation recently. 
