Evaluation and prediction of carbonate karst reservoirs in the Ordovician buried hills beneath the Tarim basin: An example east of the Lungu7 well block
摘要
Abstract
The Ordovician carbonate karst reservoirs are characterized by deep burial and strong heterogeneity in Tarim basin.The karst reservoir space is primarily the later dissolution pores,karst caves and solution fissures.The study on paleogeomorphology restoration and karst vertical zonation,combined with the reservoir production performance permits to evaluate and predict the Ordovician carbonate karst reservoirs east of the Lungu7 well block.The research suggests that high-production and high-efficiency wells are mainly located in karst graves,karst crests,and karst slopes of peak-hill depressions,hill-peak depressions and karst peak cluster valleys.In the vertical direction,surface karst belts and the upper part of vertical infiltration belts are localities with good exploitation effects,where developed crack-hole reservoirs and karst cave reservoirs.In the runoff karst belts and undercurrent karst belts developed weak karst,where small-scale karst caves and karst pipelines are present,and the karst reservoirs are of the fractured-or hole-type.At last,the research predicts five high-efficient oil and gas reservoir areas,which provide the evidence for planning exploration and development of oil and gas in this area.关键词
