The Research Of Polymer-surfactant Flooding Digital Platform For J Oilfield

Offshore oil platform life is limited,generally 20 to 25 years of oilfield development cycles,to be finished in a short time of oilfield development,realize the effective utilization of resources,it must take the high speed and efficient development mode.SP flooding technology for old oil fields in transforming of the mode of development,improving the recovery degree,relieving the production decline and improve the economic benefit is of great significance.SP flooding rely mainly on the synergy between the oil displacement agents,produced a large number of physical and chemical parameters,we can use the indoor experiment and numerical simulation methods to study the effect of physical and chemical parameters to the oil displacement effect,and achieve steady oil water control.But the indoor experiment physical and chemical parameters cannot be directly input to the numerical model and the parameter source is not reliable.This paper takes the Eclipse numerical simulator as an example,presents the laboratory parameters required and the determination methods,and elaborates physical and chemical parameters when the water displacing oil.Meanwhile,perfects the physical and chemical model of the SP flooding,selects,with a special oilfield as an example,the parameter selection and makes sensitivity analysis.Ultimate purpose is to establish the digital oil displacement experiment platform.The model has been applied successfully in the oilfield.Research the reservoir numerical simulation parameters for J oilfield,optimize the injection plan.It can be proved that the SP flooding model has important significance in theory and practice.
