苏53区块水平井生产动态分类评价

苏53区块自2010年起累计投产水平井209口,随着开采井数和生产时间的不断增加,有必要对水平井进行归类分析并总结其生产规律.基于区块水平井生产数据,按照苏里格动态分类新标准,将209口水平井重新归类,并从生产特征、动储量、累产气、递减率、采收率和动态产能方面,对各类水平井开发指标进行了详尽的评价.结果表明:Ⅰ类井52...

Classification evaluation of production dynamic forhorizontal well in Su 53 block

While the horizontal well integrated development has been implemented in Su 53 block since 2010,accumulated 209 horizontal wells have been put into operation.In the face of the increasing number of development wells and production time,it is very necessary to classify and analyze the horizontal wells and summarize their production rules.In view of this,based on the production data of horizontal wells in Su 53 block,209 horizontal wells have been reclassified according to the new dynamic classification criteria of Sulige.In terms of production characteristics,dynamic reserve,cumulative gas production,decline rate,recovery rate and dynamic production,the development indexes of various horizontal wells have been evaluated in detail.The results show that 52 wells of class I have very good development benefit,113 wells of class II have good development effect,and 44 wells of class III have poor production condition and large tapping space.This classification evaluation method has been applied to the production dynamic analysis of horizontal wells in Su 53 block,and it also has certain reference and guiding significance for the development evaluation of similar tight gas reservoirs.
