Abstract
Multistage hydraulic fracturing is an important way to stimulate the tight oil and gas reservoir. Due to the number of stages and anisotropy of the long horizontal section, the flowback of each stage is important for the evaluation of the fracturing effect and the next well location deployment. At present, microseismic monitoring technology is a popular evaluation method, it can display the morphology and growth of fractures, but some other technologies are needed to analyze the flowback and production conditions of each stage. In this paper, the tracer monitoring technology is introduced by pumping a variety of tracers with the fracturing fluid into the reservoir, continuous sampling to detect the concentration of tracer concentration, then by accumulating the amount of tracer and the flowback volume to determine the flowback condition, and finally analyzing the fracturing effect of each layer. This method can achieve the qualitative and quantitative analysis of flowback situation, the flowback situation of each layer is also an important information for the future production, it can determine which stage is the main production layer
