摘要
位于该洼陷西北部的牛 871地区 ,由于地质认识的不足 ,自 85年至 99年 ,该区的勘探开发均无较大突破 ,2 0 0 0年以来 ,应用高分辨率层序地层学等新技术、新方法对该区进行沉积体系研究 ,准确进行地层划分对比 ,建立等时地层格架 ,克服了“平对”穿时的现象 ,应用效果明显。
Owing to lack of knowledge of the geology, there are not big breakthroughs of exploration and developments in Niu 871 which located on the northwest of the sag from 1985 to 1999. From 2000, a study on the sedimentary system is carried on by new methods, such as high resolution bed succession stratigraphy etc. By the accurate contrasts between the strata, the strata frames of the contemporaneity are set up and accordingly improve the strata frameworks which span multi-epoch. The application manifests that this method is feasible.
