Technical progress of ultra-deep oil and gas reservoir stimulation in Tarim Oilfield
摘要
Abstract
The Tarim Basin,functioning as China's strategic hydrocarbon resource succession zone,encounters globally recognized technical bottlenecks in the exploitation of deep/ultra-deep reservoirs.A comprehensive chronological analysis is conducted on the development trajectory of stimulation technologies for ultra-deep hydrocarbon reservoirs in the Tarim Oilfield,particularly highlighting stimulation technology breakthroughs implemented in the field's dual primary production zones:For complex carbonate reservoirs in ultra-deep intracratonic basins,an innovative integrated design approach for fracture-cavity-sys-tem identification and stimulation was proposed;for ultra-deep fractured classic reservoirs in the Kuqa piedmont zone,a series of high-efficiency stimulation technologies were developed.The research has achieved three major technological breakthroughs:First,the successful development of high-temperature resistant acid systems has significantly enhanced stimulation effectiveness in ultra-deep reservoirs;second,the breakthrough in high-density weighted-fracturing fluid technology provides critical support for ultra-deep well stimulation;third,continuous innovations in supporting process technologies have established a solid foundation for efficient development of ultra-deep oil and gas reservoirs.Integrating exploration trends with development chal-lenges of ultra-deep oil and gas reservoir in the Tarim Basin,the paper addresses the production demands and existing technical deficiencies in reservoir stimulation,including:the fundamental laboratory research on deep/ultra-deep reservoir stimulation,artificial fracture propagation mechanisms,development gaps in novel stimulation fluids,zonal isolation tools,temporary plugging materials and supporting application techniques,limitations in real-time monitoring and interpretation technologies for stimulation operations.Six key technical recommendations are proposed:(1)Establishment of an ultra-high temperature/pressure experimental platform to conduct fundamental research on rock mechanics,fluid flow,and conductivity testing;(2)Investigation fracture propagation mechanisms in high-stress complex reservoirs and develop a multi-physics coupled fracture growth model;(3)Development of high-performance acid systems resistant to 200 ℃,with breakthroughs in weighted,low-friction,thermal-stable,and controlled-acid-generation technologies;(4)Development of engineer stratified stimulation tools(including diverting agents and supporting techniques)to optimize treatment in interbedded formations;(5)Enhancement of"multi-cluster limited-entry"fracturing for ultra-deep horizontal wells to improve fracture-controlled reserves;(6)Implemention of real-time fracture diagnostics using fiber-optic monitoring and develop high-temperature downhole monitoring tools.This study not only systematically synthesizes the stimulation technology framework for"triple-ultra"(ultra-deep,ultra-high temperature,ultra-high pressure)reservoirs in the Tarim Oilfield,but also establishes critical technological foundations for China's 10 000-meter-depth reservoir stimulation endeavors.The research outcomes provide significant theoretical value and engineering guidance for promoting efficient development of deep hydrocarbon resources in China,while the innovative technological approaches may also serve as valuable references for global oilfield development under analogous geological conditions.关键词
