3) aerated foam drilling fluid
新型充气钻井液
1.
New aerated foam drilling fluid, using a special plant fiber named KWS as fluid material, not only has the characteristics of low density, high ability of removing cuttings and lower use of water, but also has the perforation of rejecting of the Na~+ s and Ca~(2+) s affection.
利用特殊植物纤维KW S作为泥浆处理剂的新型充气钻井液,不仅具有常规充气钻井液低密度、排粉能力强、节约用水等优点,还可以不受钠、钙离子的影响,提高钻井泡沫稳定性和钻井液抗盐能力。
4) temporarily blocked drilling fluid
暂堵型钻井液
1.
In order to solve the problem whether to keep the hole and block the leakage or protect the permeability of the formation,we propose the use of such polymers as Na-CMC,guar gam and konjaku flour to develop the temporarily blocked drilling fluid combined with the chain scission and degradation mechanics in modern biology.
针对钻井工程中出现的护壁堵漏与保护地层渗透性的矛盾,提出了利用羧甲基纤维素钠、胍尔胶、魔芋等聚合物,并结合现代生物技术中聚合物的断链降解原理,开发出适合于石油、天然气、地下水等钻井领域的自动降解无伤害钻井液——暂堵型钻井液,与传统的暂堵剂不同,它在钻进完成后不需要采用解堵工艺,如压力解堵、酸化解堵、油溶解堵、破胶等,从根本上改进了解堵工艺;分析了暂堵型钻井液的基本原理和两种典型聚合物的酶降解原理,并介绍了室内的粘度实验、渗透性恢复测试实验和在甘肃张掖和广西柳州的现场试验;理论和实践均证明,暂堵型钻井液能自动降解,对产层无伤害,在进行有效护壁堵漏的同时,还能在可控制的时间内显著地恢复地层的渗透性,因此具有推广价值。
