One of the important indicators of shale gas reservoir excavation is capacity evaluation, which directly affects whether large-scale shale gas reservoirs can be excavated. Capacity evaluation is the basis of system analysis and dynamic prediction. Therefore, it is particularly important to conduct capacity evaluation studies on shale gas horizontal wells. In order to accurately evaluate the horizontal well productivity of shale gas staged fracturing, this paper uses a new method to evaluate the productivity of Fuling shale gas. The new method is aimed at the dynamic difference of horizontal wells and effectively analyzes the massive data, which are factors affecting the productivity of shale gas horizontal wells. According to the pressure system, production dynamic characteristics, well trajectory position, fracturing transformation mode and penetration depth, 32 wells were divided into four types. Then, based on the classification, the principal component analysis methods can be used to evaluate the horizontal well productivity of shale gas. The new method of capacity evaluation has improved the accuracy by 10.25% compared with the traditional method, which provides a theoretical basis for guiding the efficient development of the horizontal wells of Fuling shale gas.
