The Hongliuquan oil field is an important block of the Qaidam Basin, andthough multi-round interpretation, its three-dimensional seismic data has been alittle clearer understanding of the basic geological structure and fracture systems.Through a fine interpretation and research for the reservoir group, the controlstructure and reservoir fracture to further refine the interpretation, fine explanationon the oil sands group, Using the sedimentology, reservoir geology, structuralgeology,management methods and technology to study the deposition,predict the sandstone thickness of the oil sands, ratio of sand andmud and analyze its main controlling factors. Provide the basis for the explorationand development wells deployment.1. Though the fine interpretation, we know that the system of the fracture in thisflied are main Reverse faults, but a few Normal faults. These faults can be dividedinto two groups. And these sets of fracture is governed by the Red Willow faultand the Qigequan fault.2. The group of E31is divided into I, II, III, IV four sand groups,34small layersand16#23#layer are the main reservoir. Each reservoir sandstone reservoir layeris thickness and reservoir distribution is mainly affected by the flat sedimentarymicro faces distribution3. The oil abundance of the sand body is closely related with the sedimentaryfacies, The oil abundance of Delta plain distributary channel, delta front underwaterdistributary channel, mouth bar is better than the micro facies of Flood plains,interdistributary bay, sheet sand4. The updip pinchout lithologic reservoir is the main type in the field, andbecause of the fault and Physical properties there also are Structure–lithologicreservoir, lithology-the properties of composite reservoir.5. The form of reservoir is main mud packing sand. Reservoir distribution ismainly affected by lateral changes in lithology,...
