Summary

INTRODUCTION

The petroleum industry is in the stage of rapid development from conventional oil and gas reservoirs to unconventional oil and gas reservoirs. As an important part of unconventional oil and gas resources, tight reservoirs have great potential development value (Zho et al, 2020; Xu et al, 2020; Yang et al, 2019). The development of low-permeability reservoirs includes reservoir description, hydraulic fracturing, reservoir production, and other aspects. They are a typical complex non-linear dynamic system (Yang et al, 2016). An important research content of reservoir development is the analysis and prediction of production data. The accuracy of their prediction results will directly affect the formulation of development plans, so it is very necessary to select appropriate methods. This paper summarizes the existing production capacity prediction methods and discusses the advantages and disadvantages of each method, so as to summarize the latest progress and challenges of production capacity prediction
