摘要
板桥斜坡位于歧口凹陷有利生烃区,天然气资源丰富,是后备勘探潜力区带。通过开展沙三段斜坡类型及演化特征、烃源岩类型及资源潜力、砂体展布及储集层分布等研究,优选大张坨断层下降盘板桥低斜坡区为天然气潜力目标评价区。研究发现,板桥低斜坡构造背景有利,砂体发育,储集物性好,储盖组合优越,源储一体,与斜坡构造的断裂组合构成统一的疏导体系,具备形成深部大型天然气藏的条件。依据以上结论进行了砂体精细预测、油气成藏评价等综合分析,确定预探井位,有效指导了勘探部署。
Banqiao Slope is located in the favorable hydrocarbongenerating zone in Qikou Sag with abundant natural gas resources and is the post-reserved exploration potential zone.By conducting studies on slope type and evolutionary characteristics,hydrocarbon source rock types and resource potential,sand body spread and reservoir distribution,Banqiao low slope of Dazhangtuo downthrow block was preferably chosen as the objective evaluation area of the potential natural gas.The study showed that tectonic setting of Banqiao low slope is favorable and sand bodies developed well with good reservoir properties,advanced reservoir-cap location and source storage integration.It constructed a dredging system with the fracture combination of the slope.It has the conditions to form a deep large gas reservoir.A fine sand prediction and evaluation of hydrocarbon accumulation were carried out on the basis of the above conclusions to determine the wildcat position,these effectively guide the exploration plan.
