Temporary plugging and diversion technology is simple in operation, low in overall cost, good in adaptability under different target conditions and low in construction risk. It has been widely used in Hydraulic fracturing in China. In the process of Hydraulic fracturing, timely and appropriate temporary plugging agent can effectively plug the fully transformed area, retransform the incomplete transformed area, increase the fracture contact area, improve the fracture complexity, finally realize the full coverage of the transformed section, improve the operation efficiency, and ultimately create economic benefits. The application examples of temporary plugging diversion technology in the three well conditions of refracturing well, casing variable well and infill perforation well are analyzed and summarized. The characteristics of fracturing curve and microseismic monitoring show that the microseismic events increase in most of the well reconstruction section after temporary plugging, and the improvement effect is obvious.
