Research On Reservoir Characterization Of Dolostone And Geology Modeling In Block Ym 32, Northern Region Of Tarim Basin

Recently,In Tarim Basin,the exploration of oil tend to multi-level,multi-field,Cambrian-Ordovician dolomite,as an important oil and gas exploration,is important in the future,so this paper choose Tabei Ym32 Cambrian-Ordovician dolomite as the object.According to the core,logging and seismic data,as well as Thin section observation,mercury intrusion,electron probe,combined with micro-multi-parameter analysis technology,this paper mainly focus on reservoir micro-characterization,reservoir geological modeling and analysis of reservoir genesis to describe dolomite reservoir,which may contribute to oil and gas exploration in the future.Ym32 district,the sedimentary facies is divided into restricted platform,semi-restricted platform,the type of rock is classified into micrite dolomite,crystal dolomite,finely crystalline dolomite and medium-crystalline dolomite,the types of reservoir space include pores,cave,fractures and tectonic fracture,the main reservoir factors in the study area can be summarized as lithofacies,dolomitization;namely lithofacies control the type of reservoir space combination,dissolution is the main mechanism of formation the porous reservoirs,hydrothermal transformation is also very important to reservoirs;Finally establish a three-dimensional geological model of reservoir,so that we can predict the distribution of reservoir In three-dimension to give guidance to oil exploration and development.
