Abstract

Third member of the Feixianguan Formation in the Shaguanping area displayed oil and gas exploration prospect. Nonetheless, the reservoir characteristics and favorable area are not clear, thus confining further exploration. By studying the characteristics of structure, sedimentary facies and reservoir, and combining with the characteristics of fracture development, the favorable area of reservoir is predicted. The study shows that the three segments of the Feixianguan formation are developed in the shoal microfacies. The reservoir rocks are mainly composed by marlstones, granular limestones (e.g., oolitic, spherical and bean-grained limestones), oolitic dolomites and silty dolomites. The reservoir space can be divided into three categories: pores, caves and fractures, including dissolved pores, caves, intergranular pores (dissolved pores) and intercrystalline pores (dissolved pores). The reservoir space is mainly corrosion cavitives and fractures, while the overall pore system is characterized by fractures. The average porosity is 3.82%, and the observed fractures are developed in the core. Combined with the prediction of the plane distribution of seismic fractures and the plane distribution characteristics of reservoir thickness, the favorable reservoir areas of the study area are predicted.
