吉林油田CCUS-EOR技术攻关与实践新进展
New research and practice progresses of CCUS-EOR technology in Jilin Oilfield
摘要
Abstract
CO2 capture,storage and enhanced oil recovery(CCUS-EOR)technology can greatly improve oil recovery factor and achieve effective CO2 storage,while realizing carbon emission reduction and oil recovery enhancement,so it is an important technical means to implement the"dual carbon"strategy and ensure energy security.PetroChina pays great attention to the issue of CO2 resource utilization.After systematically studying the CO2 flooding mechanism and storage potential in original,medium-high water cut,high water cut and extremely high water cut reservoirs,it develops key technologies and process equipment.And thus,a series of CCUS-EOR whole industry chain integrated technologies dominated by CO2 capture,transportation,injection,production,flooding,storage and anti-corrosion are developed.Besides,it takes the lead in the CCUS-EOR field practice in the Jilin Oilfield.And the following research results are obtained.First,the field test confirms that CO2 flooding can increase oil recovery factor by more than 20%,and a total of 320×104 t CO2 has been injected.Second,the field practice systematically reveals the CO2 flooding and storage laws in continental low-permeability reservoirs,verifies the adaptability of the whole process technology of CO2 capture and transportation,injection and production,flooding and storage,and recycling,and realizes the integration of CCUS-EOR emission reduction and efficiency improvement.In conclusion,domestic first demonstration engineering of CO2 capture,flooding,storage and recycling of the whole industrial chain and the whole process has been built in the Jilin Oilfield,and it has achieved significant oil recovery enhancement and safe CO2 storage in continental low-permeability reservoirs.What's more,this paper systematically summarizes the latest research progress and field practice understandings on CCUS-EOR in the Jilin Oilfield in recent years,predicts the application prospect of CCUS-EOR in oil and gas fields,and puts forward suggestions to promote the industrialization development of related enterprises with new quality productivity.关键词
