摘要

黄骅坳陷孔南地区沙河街期发育了沧东凹陷、南皮凹陷、盐山凹陷和吴桥凹陷,虽然这4个凹陷相互连通,但特点各异,具有双断中隆型、东断西超型和西断东超型3种结构,分别沉积了扇三角洲相、辫状三角洲相和湖相等沉积体,发育了砂岩、生物灰岩和白云岩3种岩石类型。烃源岩评价表明,吴桥凹陷有机质丰度及生烃潜力较低,其余3个凹陷均有一定资源规模。通过对这4个凹陷成藏条件类比,优选出盐山凹陷、沧东凹陷作为勘探突破的主攻方向,提出了针对凹槽、斜坡区以岩性油藏为主的勘探部署思路。

Abstract

          There are four Palaeogene Shahejie period (Es) sags of Cangdong, Nanpi,Yanshan and Wuqiao in the Kongnan area, with intercommunication and geological features. Three structural configurations of the rift in two sides and uplift in middle part, rift in the east and overlap in the west, and rift in the west and overlap in the east accepted the deposition of fan delta, braid delta, and lake facies, respectively. Thus, three lithological types of sandstone, bioaccumulated limestone and dolomite exist in the corresponding structural configuration. The results of source rock evaluation suggest that the Wuqiao sag would have the poor potential of hydrocarbon generation and the other 3 sags have a certain petroleum resource. In comparison with the conditions of hydrocarbon accumulation in the four sags, we select the sags of Yanshan and Cangdong as main exploration target and deploy the proposal of lithological exploration in the cavity and slope zone.
