低伤害控水压裂工艺在子北采油厂的应用

Application Of Low Damage Controlling Water Fracturing Technique In Xiqu-Oil Production Company

控水压裂工艺对于油田稳油控水提高开发效果意义重大,应根据储层的具体特征选择合理的压裂液体系与设计合理的压裂参数进行施工,改善开发效果[1]。延长油田子北采油厂延安组延10油层边底水活跃,油井含水上升和水淹快,严重影响了油井的采收率和产能建设。根据子北采油厂家储层具体地质特征,引进低伤害控水压力工艺技术,通过现场施工,效果显著,使子北采油厂家稳油控水和提高开发效果取得了重大突破,带来了良好的经济效益。

Controlling water fracturing technique is signality in stabilizing oil production and controlling water cut and improving development effect. In order to improve development response, it should select rational fracturing fluid and design rational fracture parameter according to characteristics of reservoir in oil and water well construction. Xiqu--Oil production company of yanchang oilfield＇s yanan formation＇s yan10 oil reservoir have a active edge and bottom water, it leads to water cut rising and watered out is fast and seriously affects recovery factor and productivity construction, It introduce low damage controlling water fracturing technique according to characteristics of reservoir. It has made a good effect through on--site construction, and makes a breakthrough in stabilizing oil production and controlling water cut and improving development effectiveness with brings a good economic benefit.
