英文摘要	Evaluation of the gas inflow profile of horizontal wells (GIPHW) is one of the key technologies to achieve a high efficiency and stable gas production in heterogeneous gas reservoirs. However, the gas inflow profiles of the YB gas reservoir cannot be determined by current methods such as theoretical modeling and production logging. In this paper, a new experimental evaluation method is proposed to determine GIPHW in the YB gas reservoir. First, gas inflow profile experiments were conducted considering different permeability combinations and injection pressure differences. Then, the drawdown-permeability-gas production chart was generated based on experiments. Finally, based on these charts, a new evaluation method for GIPHW was developed and applied in the YB gas reservoir. The numerical simulation and experimental results for GIPHW in the YB gas reservoir showed good consistency. The sensitivity analysis demonstrated three points: (1) Although the number of cores increases when the permeability difference is maintained, the GIPHW does not change. Meanwhile, gas production increases with an increasing proportion of three types of reservoir, but the reservoir-type proportion has little influence on the GIPHW. (2) Gas production increases with increasing pressure difference. The Type I reservoir has the highest production increment, followed by Type II reservoir and Type III reservoir. (3) The reservoir proportion changes in descending order affecting the GIPHW are Type I reservoirs, Type II reservoirs, and Type III reservoirs. This work provides technical support for the determination of the GIPHW and the complete optimization of horizontal wells in the gas reservoir.
