Plugging agent system as well as preparation method and application thereof
The invention belongs to the technical field of reconstruction of horizontal well shafts for oil fields, and particularly provides a plugging agent system and a preparation method and application thereof.The plugging agent system is prepared from, by mass, 30-40% of superfine cement, 5-10% of flexibilizer, 5-10% of reinforcing agent, 5-10% of dispersing agent and 30-55% of diluent, the plugging agent system solves the problems that in the prior art, a plugging agent system is low in strength and not easy to drill and remove in the later period, and the plugging agent system is easy to drill and plug, high in compressive strength, reasonable in initial and final setting time, capable of adapting to horizontal well shaft reconstruction measures, capable of providing a brand new method for horizontal well shaft treatment and refracturing and easy to apply and popularize.
本发明属于油田用水平井井筒再造技术领域，具体提供了一种封堵剂体系及其制备方法和应用，该封堵剂体系，由如下组分按如下质量百分比组成：超细水泥为30～40％、增韧剂为5～10％、增强剂为5～10％、分散剂为5～10％、稀释剂为30～55％，解决了现有技术中封堵剂体系强度偏低且后期不易钻除的问题，本发明的封堵剂体系易于钻塞、抗压强度高、具有合理的初终凝时间，能够适应于水平井井筒再造的措施，为水平井的井筒治理、重复压裂提供一种全新的方法，易于推广应用。
