摘要
低渗油田开发进入中后期,重复压裂逐渐成为低渗透油田稳产的重要措施。转向压裂通过采用桥堵剂等措施,在重复压裂改造过程中形成新的裂缝实现高效增产。经过多个油田现场实践,转向压裂技术正逐步成为重复压裂研究和应用的主要工艺。通过讨论目前应用的两种转向压裂工艺(缝内转向与缝口转向),分析了两种工艺的特征及评价手段,同时对其发展方向提出一些认识。
When developing low permeability oilfield reaches to middle or later period, repeating fracture gradually becomes important measure to keep stable production in low permeability oilfield. By measures of using bridge plugging agent etc., in the course of repeat fracture, turnaround fracture can make new fracture to increase efficiently productivity. By field practice in many oilfields, turnaround fracture gradually become main tech studied and applied by repeat fracture. Through discussion about two kinds of turnaround fracture tech applied at present (turnaround inside fracture and turnaround head-side fracture), characteristic and evaluation measure of this two kinds of tech are analyzed, and some knowledge is provided for its development direction.
