| 中文摘要:DMZ低密度无固相钻井液主要由水、高分子聚合物 (防塌剂 )、天然高分子物质 (降滤失剂 )配制而成 ,其密度稳定在 0 999～ 1 0 0 4 g/cm3之间 ,具有良好的防塌护壁和絮凝能力 ,能有效解决小口径绳索取心钻探中出现的钻杆内结泥皮、携带岩粉能力差、失水量高等问题。 |

| Abstract:DMZ low density solid free drilling fluid is mainly comprised of water, high molecular polymer and natural high molecular compound. It's density ranges from 0.999 to 1.004 g/cm 3. It possesses good quality of anti caving, protecting wall and flocculating. The problems occuring in small diameter wire line coring drilling, such as slurry cake in inner face of drilling rod, low carrying capability, high water loss and so on, can be solved with it. |
