黑帝庙地区位于西南沉积体系三角洲前缘相带,本区邻近物源,砂地比较高,属于三角洲内前缘带。根据三角洲前缘相带控油理论,高砂地比区油气成藏主要受构造控制,某种程度上制约了本区岩性油藏的勘探,本次通过层序地层学理论对该区进行了沉积演化规律研究,认为青一段沉积末期受区域上湖泛期的控制,泥质成份相对发育,因此青一段Ⅰ砂组储层物性变化快,河道砂体内部储层连通性差,具备形成岩性油藏的条件。通过地震技术应用对本区发育的河道砂体开展刻画研究,并成功指导井位部署3口,对本区的岩性勘探起到了重要指导作用。
Hei Di Temple area is located in the southwestern sedimentary system delta front facies belt, near the provenance in this area, the sand is relatively high, belonged to the delta front zone. According to the theory of deltazone oil control in the delta front, the hydrocarbon accumulation in the Gaoshadi ratio region is mainly controlled by tectonics and to a certain extent restricted the exploration of lithologic reservoirs in this area. This time, the sequence stratigraphy theory was used to deposit the area According to the study of evolution law, it is considered that the late Qinghai-Tibetian sediment was controlled by the upper-lake flooding period and the mudstone component was relatively developed. Therefore, the physical properties of the first sand group changed rapidly in the first member of the sandbody. Conditions of possession. Through the application of seismic technology, the research on the channel sandbody developed in this area has been carried out and the successful deployment of 3 wells has played an important guiding role in lithological exploration in this area.
