Adaptive Channel沉积相建模在水平井地质导向中的应用
Application of Adaptive Channel Sedimentary Facies Modeling in Horizontal-Well Geo-Steering
摘要
Abstract
The 3D geological relation between adjacent wells cannot be fully characterized by the 2D-secton geosteering technology,which usually leads to poor reservoir prediction.A geology database for the monolayer sedimentar,microfacies of braided river reservoir is established according to the modern braided river sedimentation,outcrop,structure analysis of infilling region and horizontal well data.As a constraint,a target-based Adaptive Channel sedimentary facies modeling method is used to establish a 3D sedimentary microfacies rnodel with multi-stage stacking channels and prediction models with different probabilities to guide the horizontal-well geo-steering.The corresponding horizontal-well geo-steering success rate has reached 90.9％.Comparing with that of traditional methods,the sandbody drilling rate is increased by about 8percentage points and the gas reservoir drilling rate is increased by about 5％,which results in significant test gas production and productivity.This research could provide certain technical reference for the efficient development of tight sandstone gas reservoirs with strong reservoir heterogeneity.关键词
