Research and Application of New Refracturing Technology in Low Permeability Oilfield

  • 摘要: 鄂尔多斯盆地长X储层受储层物性、压裂裂缝等因素影响,注水开发驱替效果较差,大量剩余油分布于人工裂缝两侧难以动用.为了充分动用裂缝侧向剩余油,提高油井单井产量和采收率,按照"控制缝长+多缝+提高剩余油动用程度"的技术思路,通过数值模拟计算,提出并试验形成了以"增加裂缝带宽、产生转向新裂缝"为增产机理,以"缝内暂堵、增大排量、适度规模和低黏液体"为模式的老井新型多缝重复压裂技术.现场试验表明,与常规压裂相比,该压裂技术裂缝带宽增大21 m,改造体积增大148%,平均单井增油量为常规压裂的1.9倍,取得明显的增产效果,为长庆油田低渗透储层老井重复改造提供了新的技术手段.
    Abstract: Production from the Chang X reservoir of the Ordos Basin has been declining due to the petrophysical properties of the producing formation, induced fractures,and other factors, and the displacement effect with water. As a result, there is large amount of remaining oil distributed at both sides of induced fractures, and it is difficult to tap.To optimally recover the remaining oil, improve output and recovery, according to the concept of "control of fracture length + multi-fracture fracturing + tap much remaining oil", this paper presents a new multi-refracture stimulating technology (NMST) through numerical simulation, which can increase fracture width, create new fractures in different directions, and take such measures as temporary plugging inside fracture, raising flow rate properly, using low viscous fluids, etc. Field testing shows that the single-well daily average output is 1.9 times that of conventional technology, fracture belt and fractured formation volume increased by 21 m and 148% respectively. The NMST provides a new way to improve recovery of oil in the low-permeability reservoirs in the Ordos Basin.
