Abstract


China's eastern most of the oil and gas fields , Petroleum Exploration fault block oil reservoir reserves accounted for approximately 32% of the total developed reserves in China , a major study of the fault block oil and gas fields of the significance of China's energy industry . Fault block reservoir research focuses on fault characteristics and reservoir heterogeneity , and reservoir heterogeneity and Reserves relations . The difficulty is to establish a geological model can accurately reflect the underground reservoir characteristics . Reservoir geological model consists of three parts: the model of the structural characteristics of reservoir geological model , fluid distribution model , which reservoir geological model is the core of the reservoir geological model , reserves the basis of the study . This thesis Methodist 79 - Pu 95 Sand Sand under - Sand reservoir from the formation and deposition of faults , lithology and lithofacies study , analysis of the distribution of reservoir heterogeneity and reserves impact , given the reservoir geological model of the reservoir model as the main content . Studies suggest that the complex structure of the reservoir , the study of fault development in the region , closed ; complex formation situation changes ; developed deltaic sediments lakebed fan - of slump turbidite deposition system , deep lake - semi- deep lake cream of rock salt deposition system , which types of sand bodies in the delta depositional system is favorable reservoir ; poor reservoir properties and porosity of the reservoir rock types are mainly intergranular pores , intergranular dissolved pores (inside) . Due to the fault , deposition , lithology and lithofacies impact of reservoir heterogeneity . In this thesis, after in-depth research, multi-disciplinary data , gives a more accurate reservoir geological model , pointed out the advantages of distribution of reserves position , calculation of reserves and reserve evaluation .
