Reservoir Engineering Program Of Chenghai C Oilfield

With the development of beach oilfield,the development of the undeveloped reserves,especially the low permeability reservoir,is put on the agenda.In order to meet the beach oilfield development needs of low permeability reservoir,it carried out research and design of reservoir engineering project,through scientific research,forming technology of low permeability reservoir development route of beach oilfield.This paper investigated the development experience of low permeability reservoir at home and abroad in detail.It takes ChengHai-C Oilfield for example,using the existing exploratory well test data,production data and integrated geological research to study on seepage law of low permeability reservoir,including reservoir wettability characteristics,reservoir sensitivity characteristics,characteristics of relative permeability curves,characteristics of capillary pressure curves and characteristics of dimensionless liquid production index curves.With the help of reservoir engineering study,this study analyses and demonstration the reasonable development fashion,layer series of development,well pattern,well spacing,injection-production pattern,injection-production capacity,injection-production pressure and recovery.Meanwhile,the paper uses reservoir numerical simulation technology to study the re-analysis and re-assessment of technical policy boundaries,comprehensive reservoir engineering method and numerical simulation research results,to determine a set of optimization of the development of technical indicators.Using reservoir engineering research results,this paper completed two sets of ChengHai-C oilfield reservoir engineering project.It optimized the development mode of directional well injection,directional well and horizontal well oil production finally,through the comprehensive analysis of technical index and economic index.
