Abstract

Abstract:

Faults and fractures play a key role in hydrocarbon accumulation. The Zhenjing area has been taken as study subject as it contains numerous faults and fractures resulted from intensive tectonic movements due to its location at the intersection of different tectonic units in the southwestern Ordos Basin. Based on the fine interpretation of faults and fractures in the Zhenjing area fully covered by 3D seismic acreage， this paper makes an deep study on the combination style， formation period and characteristics of fault-fracture bodies composed of faults and associated brittle fracture zone as well as the modified tight （with low permeability） sandstone. There are mainly five structural combination styles of fault-fracture bodies. On a sectional view， including graben horst， ladder， graben， flower and tight translation types， corresponding respectively to broom， en echelon， parallel straight-line， pull-apart graben and straight-line combinations on a plane view. Different combination styles have different stress background. Through seismic interpretation and C-O isotope analysis， it is suggested that there are mainly three stages of tectonic activities in the fault-fracture body belt in the study area： Indosinian， Yanshanian and Himalayan periods. The Yanshanian period is the most important period for the formation of fractures， while the Himalayan and Indosinian periods are less important. By means of K?Ar isotope analysis， temperature measurement of inclusions and thermal evolution history analysis， it is clear that the hydrocarbon accumulation in fault-fracture bodies in Chang 8 member of the Yanchang Formation occurred mainly in the middle and late of Early Cretaceous. The three-dimensional description of fault-fracture bodies was combined with the determination of temporal relationship between the formation period of the fault-fracture and the hydrocarbon accumulation to analyze the reservoir control mechanism of different combination styles of the Chang 8 member in the study area. The results show that the en echelon ladder is the most favorable to hydrocarbon enrichment， followed by the pull-apart flower-shaped graben and broom-like graben horst， and the parallel straight-line graben and straight-line tight translation style are the least favorable to hydrocarbon enrichment.
