二连盆地赛汉塔拉凹陷地质综合评价及目标优选
|
摘要
依据赛汉塔拉凹陷二次三维地震资料,并结合配套新技术和手段,对赛汉塔拉凹陷进行整体解剖、整体评价。通过层序格架的建立和沉积相分析,将研究区划分为最有利区带、勘探潜力带和继续积极探索区带等三个层次。以赛51井、赛66井、赛84井为例具体阐述对目标的评价和优选过程。通过这三口井的钻探成功,展示了赛汉塔拉凹陷有望成为二连盆地油气资源的接替区。
Based on secondary 3-D seismic data in Saihantala sag and combining with necessary new technique and tools,we implemented integral dissecting and evaluation of Saihantala sag,the studied area is divided into three levels: most favorable zone,potential zone for exploration and zone continue to actively explore by buildup of stratigraphic order framework and sedimentary analysis.Taking Sai-51.Sai-66 and Sai-84 as examples,the paper concretely expounded the process of objective evaluation and optimization,showing that the Saihantala sag is hopeful to become replacement zone of prospecting reserve in Erlian basin because of these three successful drilling holes.
