Study on Water Plugging Technology by Emulsified Viscous Oil in Block Jin16

Abstract:

Water plugging by emulsified viscous oil s a kind of advanced technology with high selectivity, which causes little damage to reservoir and brings high economic benefit for oil wells. Through a series of simulation experiments in the laboratory, the effects of temperature, water ratio, salinity, the emulsifier concentration, the viscosity of crude oil on the emulsion viscosity is studied, also long-term stability of emulsion. The following analysis of the experimental data makes the main factor affecting water plugging by emulsified heavy oil clear. By the Indoor core simulation experiment, this paper determines changes of pressure, recovery and breakthrough pressure and studies injection capacity of emulsified crude oil and sealing performance to ensure reasonable injection parameters.
