不动管柱分层压裂在坪北油田的推广应用

Popularization and Application of Immovable String Fracturing of Separate Layers in Pingbei Oilfield

由于目前油田地下油水关系变得越来越复杂,勘探开发初期单层大规模水力压裂提高单井产量的方法已不能适应对老油田的储层改造。不动管柱分层压裂工艺,以及与其相关的控缝压裂技术、同层分层压裂技术和斜井段分层压裂技术在坪北油田的推广应用,有效解决了该油田单井不能获得效益产能、压裂易窜槽等老油田开发过程中遇到的一系列难题,改善了区块整体开发效果,并取得了良好的增油效果和经济效益。

More and more complicated underground oil-water relationship makes the method of large-scale monolayer hydrofracture to increase per-well production at initial stage of exploration and development unable to apply to reservoir reform in old oilfield. The popularization and application of immovable string fracturing of separate layers technology and other technologies such as fissure control fracturing,stratified fracturing of the same layer and stratified fracturing of slant hole interval in Pingbei Oilfield has effectively solved a series of difficulties in the development process of the old oilfield and improved overall development effect,thus enhancing oil production and better economic benefit.
