Fracturing process on Pucheng Oilfield low porosity and low permeability oil reservoir applications

Pucheng Oilfield W 42,W43 block is typical of porosity,low permeability,heterogeneous reservoir,in the conventional development plan can not be cost-effective mining.Through the reservoir geological characteristics,development history and status quo analysis,the prevalence of oil blocks,four low phenomenon(low productivity,low surface,low water content,taken out of the level).Research from the reservoir fracturing process starting,for permeability reservoir,fracturing the reservoir is to improve the flow capacity,enhance oil production in a major way.Based on the W42,W43 fault block oil reservoir fracturing process research and implementation,block oil development wells and achieved good results,reservoir development indicators improved significantly.
