压裂暂堵剂的研究进展与应用

Research Progress and Application of Fracturing Temporary Blocking Agent

我国大部分的油田属于高含水,低渗透油田。提高此类油田采收率的有效措施就是重复压裂,重复压裂的核心技术是暂堵剂的使用。根据可溶性和作用原理主要可以将暂堵剂分为酸溶性暂堵剂、油溶性暂堵剂、水溶性暂堵剂。本文介绍了暂堵剂的适用场合、作用原理、性能、研究进展。结论认为,相比于其他类型的暂堵剂,水溶性暂堵剂适用范围广,性能高效,符合未来发展的趋势。最后对暂堵剂的未来的发展趋势和应用进行了总结。

Most of the oil fields in my country are high water cut and low permeability oil fields.The effective measure to improve the recovery rate of such oilfields is refracturing,and the core technology of refracturing is the use of temporary blocking agents.According to solubility and action principle,temporary blocking agents can be divided into acid-soluble temporary blocking agents,oil-soluble temporary blocking agents and water-soluble temporary blocking agents.The application occasion,action principle,performance and research progress of temporary blocking agent were introduced.It was concluded that compared with other types of temporary blocking agents,the water-soluble temporary blocking agent had a wide range of applications and high performance,which was in line with the future development trend.Finally,the future development trend and application of temporary plugging agent were summarized.
