Detailed Reservoir Description And Secondary Development Deployment In Du 210 Block

Du 210 block after 20 years of steam stimulation development,has entered the end of the development of throughput,the annual oil production dropped significantly,the decline rate increased year by year.To improve the overall development of the block effect,it is necessary to carry out the second development and deployment.Based on the high-precision seismic data of Du 210,this paper makes a seismic interpretation of the block as a whole and uses the reservoir description software to re-understand the whole Du 210 block through the fine reservoir description: The stratum is divided into two reservoirs and seven sandstone groups,among which the main reservoirs are the four sandstone groups of the lower strata,with a total of 16 small layers.The reservoir is re-implemented by seismic interpretation.The sedimentary facies of the sandstone group was studied,and the sedimentary facies of the sandstone groups were studied.The sedimentary facies of the sandstone groups were studied.The sedimentary facies of the sandstone groups were studied.Source characteristics and sand body distribution situation;Finally,the establishment of the overall three-dimensional quantitative visual geological model for the subsequent secondary development to provide theoretical support.Based on the analysis of the dynamic and static data,the paper summarizes the problems in the development process,and divides the blocks into three different regions according to the development characteristics and the degree of exploitation.The higher development area of the main body,the higher mining area in the north and the difficult area in the south,the development potential of different regions is evaluated,and the direction of the subsequent conversion development mode is pointed out.It is determined that the horizontal and vertical wells are developed in the northern and southern regions,and the main parts are developed in the form of fire drive.The horizontal well was established in the border area,21 wells were deployed in the south,7 were wells and 7 wells were deployed in the north.The feasibility of the fire in the main part was studied.
