摘　　要：KD-GWP4堵剂具有胶结强度高、防止泥浆返吐、通窄缝能力强等优点,在治理管外窜方面具有独特优势。分析了KD-GWP4堵剂工艺的选井原则,针对井身结构复杂、钻塞困难、微裂缝难于封堵等特点,结合KDGWP4堵剂的技术原理,开展了不留塞封堵工艺、"微裂缝"堵漏工艺的研究与应用,现场取得了良好的应用效果。KD-GWP4 blocking agent has the characteristics of high bond strength, preventing mud spitting back, strong in getting through the slit etc. It has a unique advantage in channeling govern- ance tube. In this paper, the principle of selecting the KD-GWP4 blocking agent is analyzed, and the characteristics of the complex of the well body structure, the difficulty of the drilling and the dif- ficulty of the micro cracks are also analyzed. Based on the principle of KD-GWP4, the research and application of the sealing technology and the application of ＂micro cracks＂ are carried out.
