摘要/Abstract

摘要： 转向压裂可以增大水力裂缝波及范围和原油与裂缝的接触面积,是低孔低渗油藏的有效开发手段。针对目前转向压裂封堵压力较低,适用于深井转向压裂的暂堵剂研究较少等问题,利用室内实验优选暂堵剂配方,通过数值模拟方法分析配方的压裂效果,并将模拟结果与现场微地震监测数据进行对比。结果表明:单独使用暂堵颗粒无法形成有效封堵,优选复合暂堵剂配方为0.8%纤维+0.5%暂堵颗粒,该配方对孔眼的最高封堵压力为8.7 MPa;优选的转向压裂裂缝体系横向波及宽度与微地震监测结果十分相近,明确了复合暂堵剂的有效性。该研究成果对提高深井转向压裂效果具有一定的指导意义。

Abstract: Turnaround fracturing can widen the swept scope of hydraulic fractures and the contact area between crude oil and fractures, and it is an effective method to develop low-porosity and low-permeability reservoirs. To address the problems of low plugging pressure of turnaround fracturing and less study on temporary plugging agent suitable for turnaround fracturing of deep wells, the formulation of temporary plugging agent was optimized by laboratory experiment, the fracturing effect of the formulation was analyzed by numerical simulation, and the simulation results were compared with the field microseismic monitoring data. The results showed that no plugging was effective by using temporary plugging particles alone, and the optimized compound temporary plugging agent formulation was 0.8% fiber plus 0.5% temporary plugging particles, with the maximum pressure for borehole plugging of 8.7 MPa; the lateral swept width of the optimized turnaround fracturing system was very similar to the microseismic monitoring results, which clearly demonstrates the effectiveness of the compound temporary plugging agent. There is much for reference of the study results for improving the turnaround fracturing effect of deep wells.

Key words: turnaround fracturing, temporary plugging agent, deep well, low porosity and low permeability, microseismic, numerical simulation
