Exploration and Understanding of Surface Technology for Medium to High Maturity Shale Oil
There are significant differences in development methods and production rules between me-dium to high-maturity shale oil and conventional crude oil.It is difficult to meet the requirements of low-cost and efficient development using traditional surface engineering construction techniques,and different types of shale oil have significant differences.Therefore,based on the physical characteristics and production rules of shale oil,research on shale oil surface technology has been carried out.Through on-site experiments and analysis,combined with the current situation of shale oil surface technology at home and abroad,this paper explores the surface technology of medium to high-maturity shale oil,including the gathering and transportation process of single pipe unheated mixed or separated transporta-tion,the metering process of multi-well cyclic metering,the dosing process of adding demulsifiers,the dehydration process of two-stage thermal chemical dehydration,the crude oil export process of pipeline transportation and oil pulling,the natural gas treatment process of molecular sieve dehydration + propane refrigeration,as well as other technologies related to ground construction such as skid-mounted,digital,and backflow fluid treatment.Through the analysis of surface technology,the ne-cessity of coordinating and optimizing development specialties such as shale oil surface engineering,res-ervoir engineering,drilling engineering,and oil production engineering is summarized.The integra-tion and linkage of above-ground and underground,rolling development,and reducing surface engi-neering investment are carried out.The process technology of closed process is adopted,differentiated treatment,and differentiated sales are put into operation to reduce oil and gas losses,increase product added value,and improve efficiency.The construction methods of skid-mounted equipment arranged in rows and digital construction are implemented to adapt to the needs of rapid production and later ex-pansion and renovation,and to improve management level.A recycling and compounding method is adopted for the treatment of backflow fluid to achieve the injection production balance and green devel-opment.
