随着低渗油田开发的深入,措施难度不断加大,压裂和重复压裂成为改善低渗油田开发效果的重要手段,但是层间和平面矛盾进一步加剧,单纯的重复压裂已不能满足目前低渗油田的开发需要,因此为适应低渗油田改善开发效果的需要,2006年引进并扩大了转向重复压裂技术在注采单元的应用力度,并获得了突破性成果,有效地改善了一些长期注水不见效或注水后水窜高含水的老大难油井的注水开发效果,减小了层间和平面矛盾,提高了储量动用程度,为改善低渗油田注水开发效果拓宽了思路。
With the development of low permeability oilfield, the measures are more and more difficult, and fracturing and repeated fracturing are the important means to improve the development effect of low permeability oilfield. However, the conflict between layers and planes is further aggravated. Simple fracturing can not satisfy the current Therefore, in order to meet the need of improving the development effect in the low-permeable oilfield, the application of diversion fracturing technology in injection-production unit was introduced and expanded in 2006, and breakthrough results were achieved, which effectively improved some Long-term waterflooding is ineffective or waterflooding waterflooding gigantic oil well waterflooding development effect, reducing the interlayer and plane conflicts, improve the utilization of reserves, to broaden the train of thought to improve the waterflooding effect of low permeability oilfield.
