纳米流体相渗曲线研究进展
Research Progress of Nanofluid Phase Permeability Curves
摘要
Abstract
Nanoparticles are widely used in oil and gas reservoir development because of their extremely small size,large specific surface area and low dosage,but little research has been reported on the phase permeability curves of nanofluids.Therefore,through literature research,the effects of factors such as the number of capillary,wettability,temperature and net effective pressure on the shape of phase permeability curves before and after the oil displace-ment by nanofluids are reviewed,the mathematical modeling methods for constructing the phase permeability curves are summarized and discussed,and the method of obtaining phase permeability curves that is applicable to nanoflu-ids is preferred in combination with the characteristics of nanofluids.This study can provide certain theoretical refer-ences and guidance for the accurate acquisition of phase permeability curves of nanofluids,the establishment of nu-merical models of phase permeability and the in-depth study of the mechanism of oil displacement by nanofluids.关键词
