Study On Reservoir Geological Characteristics In Fuyu Oil Layer In Haituozi Area

This study uses reservoir rich data such as drilling,coring,well logging in Fuyu oil layer of Haituozi area,according to the high resolution sequence stratigraphy and sedimentology,through the recognition of well logging curve feature,explored and summarized a set of suitable for stratigraphic classification and correlation technique in this area-"cle comparison、rarchical control",and use the technology divided into 12 depositional time unit in Fuyu oil layer,etablished in the fine uified stratigraphic framework.In combination with regional sedimentary background、detritus and heavy mineral analysis study on provenance,the results show that this area is controlled by the west and the southwest provenance.In the stratigraphic framework and based on the analysis of the source of sedimentary microfacies research,proposed the Fuyu oil layer of Haituozi area development delta facies,the delta plain facies and delta front subfacies is the major type of microfacies,in the north west-south east to distribution,including underwater distributary channel and distributary channel in the region development,is the favorable places for oil and gas reservoir.on the basis of the regional stratigraphic framework,sedimentary microfacies,source and distribution,use of coring well test analysis and thin section identification information,analyzes the gap of the reservoir microscopic structure,established the classification schemes of the porosity,permeability,shale content,and pore throat radius,etc,classification of reservoir,is divided into four types of the reservoir,and divide the favorable reservoir.And on this basis Deployed 8 appraisal wells.
