Abstract

Abstract: The paleo-buried-hill reservoirs are important targets for hydrocarbon exploration in the Western Sag of Liaohe Basin,China.The heterogeneity in natural fracture development is one of the main factors affecting the hydrocarbon enrichment and single well productivity in the area.Based on the analysis of analogous outcrops,drilling cores,thin sections,scanning electron microscopy (SEM) and image logging data,we study the types and developmental characteristics of natural fractures therein,and discuss the main factors affecting the development of natural fractures in the area.According to the geological genesis,natural fractures in these buried hills can be divided into 3 groups,namely tectonic,weathering,and dissolution fractures with the dominant orientation of NNE-SSW strikes.Thin section and SEM observation indicates that mineral intercrystalline fractures,cleavage fractures,cracks and mechanical fractures were developed in these reservoirs.Among others,mineral intercrystalline fractures have the largest aperture and scale with an aperture of 20-40 μm and the scale unlimited by mineral particles.The heterogeneity of natural fractures is controlled by tectonic movements,lithology,and diagenesis of the paleo-buried-hill reservoirs.The Caledonian,Indosinian and Yanshan movements are the main periods of natural fracture development.The granitoids in the metamorphic rocks,dolomites in the carbonate rocks and medium-acid rocks in the volcanic rocks are advantageous to the development of natural fractures.The supergene weathering,dissolution,and metamorphism are the constructive diageneses for natural fracture development,while the filling and metasomatic dissolusion are the destructive ones.The results provide a sound geological basis for the exploration and development of the paleo-buried-hill reservoirs in the Western Sag of Liaohe Basin.
