摘　　要：研究开发出的新型低伤害无固相压井液主要由水溶性有机酸盐、常规无机盐、工业副产物经处理得到的低成本ZC等加重剂和无机盐促溶剂、活性剂、降滤失剂等组成。密度在1.00~2.00g/cm3间可调,具有性能稳定、防膨效果好、对油层污染小、腐蚀低、抗温性能好和现场使用方便等特点,是一种具有良好推广价值的低伤害优质压井液。The new low damage solid-free well control fluid is made up of water-soluble organic acid salt, conventional inorganic salt, low cost ZC heavy loader which obtain from industrial processing by-product and inorganic salt dissolution accelerator, coagent, filtrate reducer. The density scope is 1.0~2.0 g/cm^3. It is good at stability, suppress dilatation effect, low damage, low corrosion, good temperature resistance and convenient to use.
