biostudies-literatureUnknown10(31)Jing CMultistage fracturing technology for horizontal wells has become a core technology for the effective development of shale and other unconventional oil and gas resources. Following the fracturing and modification of horizontal wells, reliable monitoring of the fracturing effect of each interval, the return of drainage, and the fluid production profile during subsequent production is an important prerequisite for further optimization of the fracturing program and sustainable and effective development. The use of coated tracer sand allows the fracturing effect of horizontal good segments to be assessed and the fluid production profile of horizontal wells to be evaluated in real-time during production. This approach facilitates the improvement of the horizontal well development efficiency.
