以储层地质学、测井地质学、油气田开发地质学等相关原理为指导,通过对鄂尔多斯盆地WD地区长2油藏烃源岩的分布与演化、构造特征、沉积相与砂体展布特征、储层物性特征等成藏主控因素的系统研究,认为巨厚的烃源岩是油气成藏的基础;水下分流河道和河口坝微相是该区长2段有利的含油相带;隆起高部位是含油的有利构造部位;高闭合度的鼻状隆起对油气藏形成具有重要的控制作用;良好盖层是油气藏形成的重要条件。在此基础上优选出有利含油勘探区,对WD地区进一步的勘探开发提供指导。
Guided by reservoir geology, well logging geology and the geology of oil and gas fields, the distribution and evolution of source rocks, structural features, sedimentary facies and sandbody distribution of Chang 2 reservoir in the WD area of Ordos Basin , Physical properties of reservoirs and other main controlling factors of accumulation, that thick hydrocarbon source rock is the basis of hydrocarbon accumulation; underwater distributary channel and estuary dam microfacies are favorable for the region 2 oil-bearing facies belt; The high uplifts are favorable oil-bearing structural parts. The high closed nose-like uplift plays an important controlling role in the formation of oil and gas reservoirs. A good capstone is an important condition for the formation of oil and gas reservoirs. On the basis of this, a favorable oil exploration area is selected to provide guidance for further exploration and development in the WD area.
