Research On Recovery Technology And Equipment Of Light-hydrocarbon Associated Gas In Changqing Oilfield

How to effectively use of associated gas resources,improve the economic and social benefit of associated gas recovery,at the same time reduce the negative influence of the ecological environment oilfield production,has now become a major oil field to solve the problem.In this paper the research situation of changqing oilfield associated gas collecting,processing and associated gas composition analysis,on the basis of first changqing oilfield associated gas was determined by the technology analysis of the main body of light hydrocarbon recovery process,namely the propane refrigeration-low temperature condensation separation process;And associated gas was determined by the technology analysis of light ends five aided process,namely the negative pressure crude stabilization of form a complete set,booster piston machine,molecular sieve dehydration,propane refrigeration auxiliary process,finally formed a complete associated gas light hydrocarbon recovery process in general;Finally,on the basis of the overall process existing in changqing oilfield associated gas light hydrocarbon recovery unit of design as a reference and through software simulation,in the process of the key equipment selection,form the skid is given priority to,modular is complementary to skiing.From at present the construction and operation of changqing oilfield,propane refrigeration-low temperature condensation separation process has the advantages of low energy consumption,low investment,can effective recovery of the associated gas condensate,craft highly optimized,operation low energy consumption,high recovery rate and the device is small,very suitable for changqing oilfield associated gas composition characteristics of rich.Light hydrocarbon recovery device adopt skid,the modular design,covers an area of saving,can well meet changqing oilfield associated gas light hydrocarbon recovery process requirement,ravines crossbar changqing oilfield,the characteristics of the complex terrain,is advantageous to the changqing oil field work of energy conservation and emissions reduction,and promote the development of associated gas light hydrocarbons recovery project.
