摘　　要：本文介绍了胡十二块试验区使用钠土悬浮体水玻璃双液法调剖剂的优缺点，研究了钙土悬浮体水玻璃调剖剂，提出了最佳使用配方。该调剖剂的调剖效果已在现场试验中得到证实。Instead of sodium clay/water glass system, calcium clay/water glass system is used in Block Hujia 12, Zhongyuan, for profile modification treatments in water injection wells. In this paper an optimum formulation for this profile control agent and an effective injection procedure (alternate injection of 20% calcium clay suspension and 1.45% water glass in several cycles) are worked out and the excellent field results of testing this agent in a well treatment are presented.
