Fine Anatomy Of Main Sand Body Of Fuyang Reservoir In Daqing Shang 9 Block

To know systematically the development and distribution characteristics of sand body in Fuyu and Yangdachengzi(Fu-Yang)reservoirs in Shang 9 block,Yushulin oil field,in this paper,using the data of drilling,logging data,3d seismic data,the development and test data,firstly by fine stratigraphic division andborehole-seism-modulus integration technique the Fu-Yang reservoir depositional time unit were divided in the study area,and the stratigraphic framework of single sand body level was established.Second on the basis of coring well facies analysis and logging microfacies models,planar sedimentary microfacies of each depositional time was drew and the vertical evolution characteristics of sedimentary facies were analysed.Finally by use of selection finely of configuration parameters,sedimentary sand body internal structure was established in unit F?71 of Fu-yang reservoir in the study area,and using the synthetic method of sedimentary microfacies control parameters,the 9 each key strata reservoir flow units were drew in the study area.Fu-Yang reservoirs could be divided into 75 sedimentary units in the study area.There are Delta distributary plain and front subfacies,and distributary plain subfacies consists of subject,distributary channel,abandoned channel sand,the second class of overflow and shore shore sand and distributary bay microfacies,and delta front subfacies consists of underwater distributary channel,sand sheet,sheet sand,seat,seat around the outer edge and distributary microfacies.Divided into A,B,C,D,E1 and E2,6 types of flow unit,in which A class is the best reservoir property of flow unit.Through the study of the paper provides reliable basis of subsequent development,deployment and remaining oil potential in Fu-yang main oil reservoir in the study area.
