Xing Zi Chuan Oil Lou Ping Area Of Reservoir Geological Study

Louping Oil field is located in southwest of Ansai County, in the middle part of Yishan slope of ordos Basin, belongs to the up-producing area of Yanchang petroleum company. The area has discover Triassic Yanchang group and Jurassic Yanan group etc.Based on the sedimentary petrology, reservoir geology, logging geology and petroleum geology theory as the foundation, embarks from the field outcrop data, using outcrop, core and drill log data, follow the basic principles of sedimentary petrology, combined with the feature of the sedimentary environment and facies, the ground and underground, the combination of macro and micro methods, analyzing the characteristic of rock facies and logging facies and single well sedimentary facies evolution and phase section is established. The comprehensive geological study on Jurassic yanan group、Chang 6, Chang 7, Chang 8, Chang 9 and Chang 10 group in Triassic Yanchang Formation of production plant of Xingzichuan Louping area,analysis of stratigraphic classification and correlation and the distribution law of clear work area the horizon of the sedimentary microfacies and sand body distribution rule, recognizing reservoir macroscopic and microscopic characteristics, find out causes and relatively high permeability reservoir control factors and the relatively high permeability reservoir distribution, determine the reservoir plane distribution rule, the comprehensive reservoir test results, determine the favorable exploration target area, provide theoretical basis for further exploration and development.
