摘　　要：综合应用4种统计方法(油气藏规模序列法、发现过程法、广义Parato分布法、地质模型与统计模型综合法)预测了苏北盆地东部海安凹陷上白垩统泰州组的油气地质资源结构和油气最终可探明储量。研究表明,该区油气远景资源为7877×104t,地质资源期望值为4961×104t,分布在142个油气藏中,待发现的单个油气藏储量分布在(5～600)×104t之间。这反映了苏北盆地东部泰州组的勘探程度不高,仍有勘探潜力。The petroleum geology resource and the resource structure of the Upper Cretaceous Taizhou Formation are evaluated with four statistical methods in the east of Subei Baisn,which are the pools size sequence method, the discovery process method, the generalized Parato distribution method, and the geological and statistical model method. The results showed that the prospective petroleum resource of Taizhou Formation is about 7 877 ×10^4t, and the expected value of petroleum geology resource is about 4 961×10^4t, which distribute in about 142 pools, and the single scale of undiscovery pools is from 5×10^4t t to 600 ×10^4t t. The exploration degree of the Taizhou Formation is not high in the east of Subei Baisn,and the exploration prospect is still broad.
