摘要
控水增油一直是老油田措施的重点工作,化学堵水为了常见的堵水措施,但对于高温地层研发一种新型堵水剂成为了目前需要解决的问题。优选了4种抗高温单体,基于丙烯酰胺,合成4种共聚物凝胶体系,并通过成胶时间和凝胶强度评价凝胶体系性能。最终确定了2种共聚物凝胶体系具有较好的堵水性能,实验结果为堵水措施的实施提供借鉴。
Water control in water control has been the key work of old oilfield measures.Chemical water plugging is a common water plugging measure,but a new type of water plugging agent for high temperature formation has become a problem to be solved at present.4 kinds of high temperature resistant monomers were selected.Based on acrylamide,4 kinds of copolymer gel systems were synthesized,and the gel system performance was evaluated by gelation time and gel strength.Finally,the 2 kinds of copolymer gel system has good water plugging performance.The experimental results provide reference for the implementation of water plugging measures.
