Estimating Perspectives of Oil and Gas in New Strata in the Southern and Surrounding Dayangshu Basin

Abstract

On the basis of elaborating on the regional geological background, this paper analyzes the lithological and sedimentary characteristics and explorative prospects of new strata with oil and gas in the southern and surrounding areas of Dayangshu Basin. Based on the latest high-precision airborne gravity and magnetic comprehensive survey data, combined with the latest data from geological explorations, physical surveys, and drilling, and the use of basin structure layering combination methods, we clarified the characteristics of the bottom of the Jurassic–Cretaceous and the occurrence characteristics of the Upper Paleozoic in the study area and revealed the determinative effect of multi-period structures on the most important sedimentary layers. Then, we summarized the accumulation conditions and prediction methods of hydrocarbons and proposed the oil and gas prospects of these deep new strata. The results show that the Liuhe Sag in Dayangshu Basin, the depression in the northeast of Longjiang Basin, and the northern parts of the Taikang swell have good source–reservoir–cap combination conditions and favorable structural characteristics for oil and gas, where there is a high potential for exploration.

“…The first contribution we will consider, by Liu et al [1], is strictly applied and describes the integration of new high-precision airborne gravity and magnetic data with data from geological exploration and drilling, and the resulting improved understanding of the Jurassic-Cretaceous and the Upper Paleozoic strata of the Dayangshu Basin, China, and their potential to host oil and gas reservoirs. The conclusion of this contribution is that three specific zones, the Liuhe Sag in Dayangshu Basin, the depression in NE Longjiang Basin, and the northern parts of the Taikang swell, have high potential for oil and gas exploration.…”
