摘　　要：无机沉淀物作为堵水调剖剂是目前提高条件苛刻油藏开发效果的一种有效方法。介绍了无机沉淀型堵剂的主要类型，有氢氧化物型（分为氧化铝类和氢氧化镁类）、无机盐沉淀型、热敏型、醇诱导盐型、无机一有机复合型等。同时介绍了无机沉淀的堵水调剖机理及其在现场的应用效果，结果表明单液法水玻璃堵剂粘度低，易进入地层，适应范围在40—130℃，封堵率高，突破力大，效果良好。指出，无机堵剂具有耐高温、抗高盐、廉价、对环境无害等特点，是提高苛刻条件油藏开发效果的一种有效方法。The inorganic precipitator used as water shut - off agent and profile modifier in the oilfield is an effective means for the exploitation of oil deposit under harsh conditions. The main types of this kind of water shut - off agent including hydroxide （ alumina and magnesium hydroxide ）, inorganic salt, heat - sensitivity, alcohol - induced salt and inorganic - organic composite etc. are introduced. Meantime, the water shut - off mechanism of inorganic precipitation agents and their application effect on site are also introduced. The results show that the water - glass type water shut - off agent is an excellent agent with low viscosity, high shut - off rate and easy to enter the earth. The suitable operating temperature is in the range of 40 - 130 ℃. This kind of shut - off agent has the features of high temperature and salt resistance, cheapness and non - pollution to environment.
