Research On The Fine Reservoir Description And Comprehensive Treatment Plan Of The 1st Member Of The East Member Of Nanpu 1-1 Block

Research area nanpu 1-1 area east a reservoir for the overall development in nanpu fault rise 1 set of typical complex fault block oil reservoir,with small fault block area,small sand body thickness,layer number,the more complex connected relationship etc.Since put into development by water injection revealed a high degree of control and low degree of use,well not injection Wells and oil well water and so on many contradictions.Need to carry out the system of fine reservoir description and comprehensive treatment project to develop targeted.Aiming at the exposed problems in the study area,eastern nanpu 1-1 a reservoir for fine reservoir description and complete the comprehensive treatment plan formulation.Main achievements made in the research as follows:1.By multiwell constraint 3 d seismic inversion,which can effectively improve the thin sand body seismic recognition accuracy.Multiwell constraint of 3 d seismic inversion and geostatistics method,which can effectively combining logging information and seismic information,thin sand layer can significantly increase the complex fault block reservoir identification precision,the highest recognition accuracy of the sand body in the study area can be up to 5 m.2.Make full use of production performance data,can be in sand body recognition,on the basis of further judgment interwell sand body connectivity to guide fine set of injection-production measures.Logging data of high longitudinal resolution interwell sand body connectivity to judgment,well seismic combination can partly predict interwell sand body connectivity,but explain the results there are still many solution.Make full use of the pressure test,oil and gas production data,such as water law of diminishing can could not judge the connected relationship of well logging,seismic information for further detailed interpretation,formation well combining,movement and technical system of earthquake.3.To formulate and complete the comprehensive control scheme in the study area,effectively guide the fine reservoir waterflood development in the study area.
