A Review of Prediction Methods for Permeability in Clastic Reservoirs

Abstract

Accurate prediction of permeability in clastic reservoirs is of great significance for oil and gas exploration and development. This paper provides a comprehensive review of prediction methods for permeability in clastic reservoirs, including analytical methods, experimental testing, and numerical simulation. By comparing the three methods, it is found that the analytical method has the advantage of a theoretical basis and fast calculation speed, but the simplifying assumptions regarding reservoir structure may lead to inaccurate results. The experimental testing method directly measures the flow performance of rocks, but it is constrained by sample acquisition and experimental conditions. The numerical simulation method considers various influencing factors and simulates real reservoir conditions but requires extensive calculations and accurate parameter inputs. Future research can further develop the analytical method and numerical simulation method to improve prediction accuracy by incorporating actual data from experimental testing, leading to a more comprehensive and accurate prediction of permeability in clastic reservoirs.
