摘要
沉积期构造转换带是沉积碎屑物最主要卸载区,是各种砂砾岩体和有利储集层分布的主要区带;沉积期后构造转换带,使储集层构造特征发生变化,各种非构造油气藏集中分布。研究沉积期构造转换带的储集层分布有利区带特征、寻找沉积期后构造转换的油气成藏有利区、开展储集层分布和构造有利区带的匹配关系评价,是构造转换带精细研究和油气藏勘探的重要手段。胜坨地区通过构造转换带精细研究,勘探取得了重大发现。
Depositional structural transposition zone is the most important discharge area of clastic sediments and the main zone for distribution of various sand-conglomerate bodies and favorable reservoirs. In post-depositional structural transposition zone, central distribution of a variety of non-structural reservoirs takes place due to variation of reservoir characteristics. Therefore, to study the favorable zone characteristics of reservoir distribution within depositional structural transposition zone, to search for the areas of favorable hydrocarbon accumulation within post-depositional structural transposition zone and to carry out the evaluation of matched relations between reservoir distribution and favorable structural zone are the key method for such a detailed study and reservoir exploration. Shengtuo area in Dongying sag has obtained great discovery for petroleum exploration by using this method.
