野外模拟类比调查对油田地质研究用处很大,通过冀中地区潜山油藏碳酸盐储集层的野外模拟调查,并解决了油田内中、上元古界及古生界层序问题;指导了油田地下断层裂缝的分布规律研究;明确了油田潜山构造的北东向断层展布。类比研究潜山古岩溶的发育特点为:晶洞、孔洞顺层分布,大型溶蚀缝、洞多沿断裂分布,是流体运动的主要通道。潜水面附近是水平岩溶发育带,任丘古潜山有三个水平溶蚀带。储渗空间类比研究认为,冀中油藏储集层类型主要有:缝一洞一孔复合型、溶洞一裂缝型及似孔隙型三种。
The field analogy investigation is of great use to the geology research of the oilfield. Through the field investigation of carbonate reservoirs in buried hill reservoirs in Jizhong area, the sequence problems of the middle, upper Proterozoic and Paleozoic in the oilfield are solved. Guided the distribution of underground fractures in the oil field and clarified the northeastern fault distribution of buried hill structures in oilfields. The development of the ancient karst in the buried hill is analogous to that of the crystal cave, the bedding distribution of the hole, the large-scale dissolution seam and the distribution of faults along the cave. It is the main channel of fluid movement. Near the surface of the submarine is a horizontal karst development zone, Renqiu buried hill has three horizontal erosion zone. The analogy of reservoir porosity shows that there are mainly three types of reservoirs in Jizhong reservoir: one pore-perforation, one cave-like pore and three pore-like.
