摘　　要：在油田开发的中后期,为了提高油田开采率需要进行注水开采。同时,由于油田地层存在非均质性现象,因此呈现产水率逐年上升而产油率逐下年降的趋势。基于这种情况,为了进一步提高油田的原油开采率,不断提高油井堵水以及注水井调剖,已成为我国油田开发工作中的重要措施。在进行油井堵水和水井调剖措施时,耐盐性堵水剂的应用对油田原油开采具有至关重要的影响。新型耐盐性堵水剂具有良好的遇水鼓胀性能,在高矿化度的水中也能够起到良好的膨胀作用,能够有效改善地层吸水剖面,为提高原油开采率发挥积极的作用。对新型耐盐性堵水剂的合成及性能进行深入分析和研究,并结合实际情况提出科学合理的建议,为我国油田开发建设提供更多可靠的参考依据。In the middle and late stages of oilfield development,in order to improve the oilfield recovery rate,it is necessary to carry out water injection production.At the same time,due to the heterogeneity of the oilfield strata,the water production rate increases year by year and the oil production rate decreases year by year.Based on this situation,in order to further improve the crude oil recovery rate of the oil field,the continuous improvement of oil well water plugging and water injection well profile control has become an important measure in my country's oil field development work.In oil well water plugging and water well profile control measures,the application of salt-resistant water plugging agents has a crucial impact on oilfield crude oil production.The new type of salt-resistant water-blocking agent has good swelling performance in contact with water,and can also play a good swelling effect in water with high salinity,which can effectively improve the water absorption profile of the formation and play a positive role in improving the recovery rate of crude oil.In this paper,the synthesis and performance of a new type of salt resistant water plugging agent were analyzed and studied in depth,and scientific and reasonable suggestions were put forward based on the actual situation,so as to provide more reliable reference for oilfield development and construction in China.
