摘要
Abstract
Gel water plugging is the main technical method for recovery in the middle and late development of Tahe Oilfield.As the reservoir temperature and salinity continue to increase,the water plugging effectiveness of a single gel system is low,and its system development and use of water plugging materials urgently need to be optimized and improved.In this regard,this paper is based on the research of two independently developed sets of high temperature resistance,high salinity and dilution resistance water plugging systems.Through infrared,thermos-gravimeter,rheology and other analyses,the dilution resistance and compatibility of gel materials are systematically evaluated.At the same time,based on core experimental simulation,a dynamic plugging model for the collaborative application of the two gel systems is proposed to compound water plugging to further improve the dynamic plugging rate and plugging effect.Results show that the two gel systems can be applied to high temperature conditions of 140 ℃ and have good dilution resistance in water with a salinity of 24×104 mg/L.While ensuring good compatibility of the two gels,they are used synergistically.Their excellent erosion resistance makes the collaborative water plugging rate greater than 99%.Studies have shown that different gel systems with good compatibility can combine to block water and have good application potential in high temperature and high salinity environments.关键词
