doi:10.3863/j.issn.1000-2634.1995.04.011

Abstract

Abstract: This paper makes a comprehensive analysis of the factors that affect acid fracture productivity, such as production pressure drop, non Darcy effect, reservoir pollution,fracture size and the conductivity change along the fractures, etc, derives and establishes the performance prediction model of 3-D acid fractured well production. Simulation calculation shows that fracture closure stress and rock embedment strength are important factors influencing acid fracturing suitability, and non Darcy effect, reservoir pollution and fracture closure strength will reduce the produetion of wells.However the fracture size and conductivity designed optimumly and resonably will increase the production.

Key words: Acid fracturing, 3-D analysis, Percolation, Fracture conductivity, Formation damage, Performance analysis, Productivity, Mathematical simulation
