为了查明冀中坳陷北部中生代逆冲构造的发育期次以及逆冲构造对潜山储层发育的改造作用,利用新处理的高精度三维深度域地震数据,结合钻井和野外露头资料,开展了深潜山内幕断裂体系(尤其是逆冲构造)的精细解释以及逆冲构造对潜山储层发育影响的研究.结果表明:冀中坳陷北部中生代至少发育2期规模较大的逆冲构造,即印支期受到扬子板块向北俯冲作用的影响而形成的近EW向逆冲构造,燕山早期受到中国东部古太平洋板块NW向俯冲作用的影响而形成的NE向逆冲构造.利用钻井岩心和测井成像等资料,证实了杨税务潜山逆冲构造对于碳酸盐岩深潜山储层的裂缝发育和多期、多种形式岩溶作用的发生具有重要影响.

In order to ascertain the development stages of the Mesozoic thrust structures in the northern Jizhong Depression and the the influence of the thrust structures on the development of buried hill reservoirs in different periods,the deep buried internal fracture system (especially the thrust structure) was finely interpretated and the balanced sections were recovered by using the newly processed high-precision three-dimensional depth seismic data, drilling data and field outcrops data. It is revealed that at least two large-scale thrust structures developed in the northern part of Jizhong Depression in Mesozoic, that is, the near EW thrust structure formed during Indosinian period under the influence of the northward subduction of the Yangtze Plate, and the NE thrust structure formed in the early Yanshanian stage under the influence of NW subduction of the Paleo-Pacific plate in eastern China. Based on the data of drilling cores and well logging imaging, it is verified that the thrust structure has an important influence on the fracture development of carbonate deep buried hill reservoir and the occurrence of various karstification in Yangshuiwu buried hill.
