Study On Chang 8 Reservoir Injection-production Corresponding Ralation In Zhuang 36 Area Of Heshui Oilfield

Zhuang 36 area located in the south of HeShui, which is an typical ultra-low permeability reservoir, the exploited horizon is c8,The oil reservoir has made the stable development result since 2009, but some unfavourable factors of influencing development result have appeared,for example:waterflooding pattern become complicated, injection does not correspond to other issues,specific performance is is uneven absorption cross section, the well water cut, low-yielding wells more inefficient, and the overall development of the district level lower.Analyzing this reason, the reservoir properties is poor, micro fractures and strong heterogeneity, etc.In this article, the development geology, reservoir engineering research-based, By studying the fine correlation of minor layers, sedimentary micro-facies, reservoir characteristics and properties distribution,4-property relationship, flow unit classification. For the development performance,the injetion-production correlation has been definited,and supplemented by measures to perfect injection/production well pattern, establish of effective displacement system, such as perforation adding, fracturing and flood parameter modification for combined HeShui oilfield development adjustment programs to provide a scientific basis for improved reservoir development.
