Characteristics of the Mesozoic faults in Yanchi area and the petroleum geological significance, Ordos Basin

Abstract

Abstract: Faults played an important role in controlling oil accumulation in Yanchi area in the northwestern Ordos Basin. Based on the analysis of the regional geological data and combined with 2D and 3D seismic interpretation results, characteristics of the Mesozoic faults and their relationship with oil reservoir are studied by using technologies such as electron spin resonance (ESR) dating, calcite U-Pb isotope dating,equilibrium section restoration, and tectonophysical simulation. The results show that three stages of faults were developed in Yanchi area. The NW trending fault system in the Indosinian had a small scale and was mainly developed in the Triassic Yanchang Formation; The nearly NS trending fault system in the Yanshanian had the largest scale, with large fault throw and complex lateral and vertical distribution patterns; The NEE trending fault system in the Himalayan had a relatively large scale, late development period, and strike slip feature to a certain extent.The three stages of faults were formed by the regional stress of NW, nearly E-W and NE-SW directions respectively, and the nearly S-N faults were closely related to the activities of the major faults in the western basin margin. The NW trending fault system in the Indosinian connected source rock to reservoir, which delivered good configuration between migration and sealing, showing the most favorable conditions for the accumulation of oil and gas reservoirs. In addition, faults supported to improve the reservoir physical properties to some extent. When the oil well is close to the fault, oil accumulates will be easily accumulated in high permeability reservoirs in the high structural parts and high-yield production will be achieved.
