摘要
Abstract
With the development of water injection and over exploitation of oil and gas reservoirs,the problem of water pro-duction from oil and gas wells has become increasingly prominent.Water plugging operations are usually used to enhance oil recovery and water drive efficiency.Among them,selective water plugging agents have received widespread attention due to their ability to achieve precise water plugging and reduce damage to the reservoir.However,the strength and temperature resistance of the selective water plugging agents currently in use are limited,which greatly restricts its application in high-temperature and high-pressure formations.Therefore,based on the idea of the non-solvent-induced phase inversion method(NIPI),a new type of selective liquid water plugging agent with high-temperature resistance and high-strength has been devel-oped based on plant fibers and high-strength polymer blends.The water plugging agent can achieve a phase transition from a low-viscosity liquid to a high-strength solid material upon contact with water,thus achieving precise water plugging.At the same time,the selective plugging success rate,temperature resistance,and compressive properties of the water plugging agent were evaluated.The study showed that the water plugging agent has good fluidity and can achieve precise selective water plug-ging of the water layer.At the same time,its temperature resistance can reach 120 ℃,pressure resistance can reach 9.99 MPa,and water blocking rate to 100％.关键词
