中文摘要：

利用海拉尔盆地贝尔凹陷油气勘探过程中获得的地质、物探、井筒等资料,结合油气资源量评价、圈闭形成、油气成藏等条件,对已钻圈闭的油源、储层、盖层、圈闭、匹配关系等要素进行了分析.采用二因素圈闭评价方法,在油气成藏研究基础上,建立了贝尔凹陷圈闭地质风险评价标准,并对凹陷所有圈闭进行了综合评价与优选排队,指出有利的圈闭钻探目标.

英文摘要：

By means of the data of the geology, geophysics, well bore and so on obtained in the course of the petroleum exploration in Beier Sag of Hailar Basin, integrating with the conditions of the reserves evaluation, trap formation, hydrocarbon accumulation and so forth, the following factor analyses are conducted： the oil resources, reservoirs, cap rocks, traps and their matching in the penetrated traps. By adopting the trap evaluating method of binary factors, on the basis of the studies of the petroleum accumulation, the evaluating standards for the geological risk of the sag are established, and moreover the comprehensive evaluation and optimal grading are conducted for all the traps in the sag, finally the favorable trap targets for drilling and penetrating are pointed out.
