致密储层孔隙结构对渗吸的影响研究进展
Research Progress on the Impact of Tight Reservoir Pore Structure on Spontaneous Imbibition
摘要
Abstract
Against the backdrop of the gradual depletion of conventional oil and gas resources,unconventional oil and gas resources,represented by tight oil resources,are increasingly gaining importance in energy development and utilization.However,compared to conventional reservoirs,the pore structure of tight oil reservoirs is highly complex,featuring with wide distribution of pore sizes,diverse pore types,and well-developed pore throats.All these factors pose significant challenges to the exploitation of tight oil reservoirs.Therefore,a thorough research on the pore structure and spontaneous imbibition mechanism in tight oil reservoirs is crucial for improving tight oil re-covery rates.Based on this,through literature review,this paper provides an overview of the research on the pore structure and imbibition mechanism of tight oil reservoirs,introducing characterization methods for pore structure,research progress on tight oil pore structure,the impact mechanism of pore structure on tight oil imbibition mecha-nism,and summarizing and prospecting the research progress in this field.This study can provide reference for the development of crude oil production in tight oil reservoir and promote the development of tight oil recovery technolo-gy.关键词
