To maximize lifecycle recovery and establish an efficient production strategy for shale oil horizontal wells, this study focuses on the second member of the Funing Formation in Block A, North Jiangsu Basin. Utilizing integrated geo-engineering numerical simulations, key parameters such as post-fracturing shut-in duration and stewing time were systematically optimized. Results identified two critical thresholds: a 20-day shut-in period post-fracturing and a 15-day stewing interval, which enhance fracture-matrix pressure diffusion and fluid interchange while avoiding excessive operational delays. These optimized regimes mitigate rapid production decline associated with natural energy depletion, offering actionable insights for improving EUR (estimated ultimate recovery) in continental lacustrine shale reservoirs with complex lithology and heterogeneous permeability.

摘要

To maximize lifecycle recovery and establish an efficient production strategy for shale oil horizontal wells, this study focuses on the second member of the Funing Formation in Block A, North Jiangsu Basin. Utilizing integrated geo-engineering numerical simulations, key parameters such as post-fracturing shut-in duration and stewing time were systematically optimized. Results identified two critical thresholds: a 20-day shut-in period post-fracturing and a 15-day stewing interval, which enhance fracture-matrix pressure diffusion and fluid interchange while avoiding excessive operational delays. These optimized regimes mitigate rapid production decline associated with natural energy depletion, offering actionable insights for improving EUR (estimated ultimate recovery) in continental lacustrine shale reservoirs with complex lithology and heterogeneous permeability.
