摘要
以改性落叶松栲胶为主料研制的高温堵水剂，适用于油田采油用高温堵水、调剖凝胶。论述了落叶松高温堵剂的凝胶原理、性能及影响因素。给出了落叶松高温堵剂适用温度范围、封堵强度、封堵率和残余阻力系数的试验结果。
The high temperature plug agent made mainly from larch tannin is applied to plugging water at high temperature and adjusting section for oil extraction in oil field. Its gel principle function and influence factor are expounded. The applied temperature scope, plug intensity, plug rate and coefficient of remains resistance are also given.
