安塞油田王窑区套损井治理技术研究

Technical Researches on Ansai Oilfield Casing Failure Well in Wangyao Development Area

安塞油田王窑区套损井治理工艺主要有常规机械隔采,随着近年来油田含水上升,同时受井筒结垢、套管外腐蚀加剧等因素影响,常规套损机械隔采治理工艺存在隔采有效期短、起钻成功率低等问题。为此,结合不同类型套损井,开展套损井治理工艺研究与应用,并对几种治理工艺进行了分析评价,为套损井综合治理提供了技术借鉴。

Conventional mechanical layering production are mainly used in tackling Wangyao development area casing failure well.Recently,with the rise of moisture content in the oilfield,fouling on the well bore,as well as increasing corrosion on the external casing,as a consequence,the traditional layering production method may lead to short-time effectiveness and low success rate of drilling.In order to deal with it,different types of casings are combined to develop technical research and application on the casing failure well control,and analyses and evalutions can be made on the developed control methods,providing some technical references for the comprehensive control on the casing failure well.
