Abstract

Abstract: Infiltration adjustment is one of the main methods to improve recovery in the middle and late stages of gas reservoir development, but the adjustment effect is not ideal at present due to the inadequate understanding of threshold of adjustment implementation. Taking the typical tight sandstone gas reservoir of Xinchang JS₂ as an example, we study the economic and technical threshold for infiltration adjustment of different reserve areas through economic evaluation, dynamic analysis and numerical simulation, and put forward specific technical suggestions. In type I reserve area adjustments should be made to both vertical and horizontal wells when the formation pressure is greater than 59% of the original formation pressure; when the reserve abundance is greater than 4.96×10⁸ m³/km², adjustments should be made to horizontal wells; when the formation pressure is at 47%~59%, adjustments should be made to vertical wells only. In type II reserve area, when the formation pressure is greater than 67% and reserve abundance is greater than 2.03×10⁸ m³/km², adjustments can be made to both vertical and horizontal wells; when reserve abundance is less than 2.20×10⁸ m³/km², adjustments should be made to vertical wells, and when reserve abundance is greater than 2.34×10⁸ m³/km², adjustments should be made to horizontal wells; when the formation pressure is at 51%~67%, adjustments should be made to vertical wells only. In type III reserves area, adjustments can be made only to horizontal wells when the formation pressure is greater than 88%of the original formation pressure and reserve abundance is greater than 1.30×10⁸ m³/km². Ti is estimated that recoverable reserves can increase by 4.02×10⁸ m³ and recovery by 0.67% through infiltration adjustment.

Key words: tight sandstone gas reservoir, infiltration adjustment, numerical simulation, formation pressure, reserve abundance
