Evaluate Application Effect In Jingbian Gas Field Low Permeable Carbonate Rock Gas Reservoir Dynamic Analysis Skill

Jingbian gas field has been development for ten years. Because of long building period, the whole gas field pressure decline disproportionate. And for the reservoir aeolotropy,causing high production gas well alternate with low production gas well, and surface pressure decline differently.Some low production surface pressure is lower than6.4MPa, that cause gas well can’t continuous production,most of gas well surface pressure at9MPa.It will continue product for two years that gas field surface pressure deceline to6.4MPa according to production planning at present.To extent years of stable production,it has to launching boost pressure test,predicting boost pressure time,choosing boost pressure device type and boost pressure mode, organizing boost pressure program quickly,predicting years of stable production for boost pressure and others development index.Because of development feature and main problem that mention before, next research is necessary to extent years of stable production and enhance development effect:enchancing rolling evaluate and research arounding gas field, launching gas well second reconstruct actively, evaluating remote ages reservoir,enhancing low production gas well deliqufication technique research and spread, surveying gas well oil tube and annular tube corruption.According to gas reservoir dynamic analysis in Jingbian gas field,it can be extending years of stable production,checking gas field production, raising gas field recovery ratio.
