塔里木盆地深层—超深层海相碳酸盐岩油气勘探成效、启示及前景
Achievements,implications,and prospects of deep to ultra-deep marine carbonate hydrocarbon exploration in the Tarim Basin
摘要
Abstract
The exploration of deep to ultra-deep(burial depth>6 000 m)marine carbonate rocks in the Tarim Basin has undergone four major shifts in exploration thinking:paleo-structure→buried-hill karst→reef-shoal body karst→interlayer karst→fault-controlled karst.The"facies-fault-karst"three-element reservoir-controlling model and the"source-fault-reservoir-cap"four-element jointly controlled hydrocarbon accumulation model have been established.Supporting key technologies,including high-density wide-azimuth 3D seismic acquisition in desert areas and strike-slip fault characterization have been developed.The exploration strata have extended from the Ordovician to the strata below the Cambrian salt at depths of 10,000 m,and the exploration domain has expanded from paleo-uplifts to slopes and depressions.Large oil and gas fields such as Tazhong No.1,Halahatang,and Fuman have been discovered in the Middle-Upper Ordovician.Breakthroughs have been successively achieved within the Upper Cambrian-Lower Ordovician in wells Xiongtan-1 and Guotan-1,with the favorable exploration area for inner dolomite exceeding 30,000 km².Furthermore,Well Shendi Take-1 obtained natural gas discovery in the 10,000-m-deep subsalt Cambrian,confirming the hydrocarbon exploration potential of ultra-deep strata.This paper systematically reviews the theoretical and technological innovations driven by the four exploration thinking shifts and the implications gained from their field application,and looks forward to the multi-layer three-dimensional exploration prospects and key research directions of the Sinian-Ordovician carbonate sequences during the 15th Five-Year Plan period,providing theoretical support and practical paradigm for the sustained reserve growth and production enhancement of ultra-deep marine carbonate oil and gas in the Tarim Basin.关键词
