摘要
截止2019年长庆油田采气四厂自营区块历年累计完钻水平井已达220口,砂岩钻遇率、有效储层钻遇率、试气无阻流量等水平井实施效果总体较好,但部分水平井静态实施效果差、投产后产能低.随着气田开发的深入,当前储层品质逐渐变差,心滩、边滩类厚层箱装砂体逐渐减少,有效储层发育规模小,水平井导向难度增大,对储层改造工艺要求增高.这就要求水平井井位部署、地质导向、储层改造方面需要采取更加精细有效的措施,才能提高水平井开发效果.文章从上述角度,总结分析了采气四厂自营区块水平井开发面临的问题,并针对性提出了相应改进方法,对苏里格气田水平井开发具有指导意义.
There are 220 horizontal wells in gas production plant No.4 of changqing oilfield company,the development index including the rate of sandstone drilling,the rate of effective reservoir and open flow capacity is good overall,but some horizontal well’s development indexis bad,so the capacity is low.Reservoir quality gradually deteriorate within the development of gas fields,The thick box sand body gradually decrease and the effective reservoir size is small,the reservoir reformation demand is increasing.More elaborate and effective measures are needed in terms ofhorizontal well deployment,geosteering and reservoir reformationto improvehorizontal well exploitation effect.The articlesummarizes the problem of horizontal well exploitation,and gives some methods to the problem which possessguiding significance for horizontal well exploitation in Sulige gas field.
