产品性能、特点 PRODUCT PERFORMANCE AND CHARACTERISTIC
“金标”CMC作为钻探泥浆体系中的水溶性胶体，组成钻井液。
"Jinbiao"CMC can be used as water-soluble gel for drilling fluids,and can form artesian well liquor.
　●具有较高的失水控制能力，特别是PAC是高效的降滤失剂，在较低的加量下，就可以把失水控制在较高的水平，而不影响泥浆的其他性能。
　　It has good water-loss controlling ability, especially PAC is highly effective drop filter-loss agent. Even added at Iow quantity, it can control water loss at very high level, but does not affect slurry' s other characteristics.
　●形成的泥饼质量好，坚而韧。
　　It can form high quality slurry cake which is strong and flexible.
　●耐温性能好，且抗盐性能优越，在一定盐浓度下，仍能有较好的降失水能力及保持一定的流变性，在溶于盐水与溶于水比，粘度几乎不改变，特别适用于海上钻井和深井的要求。
　　It has good temperature resistance and superior anti-salt character. Under certain salt density, it can remain good water-loss capability and certain rheology, so the viscosity in salt solution is the same as in water, which is specially suitable for sea misering and deep well.
　●能很好地控制泥浆的流变性，具有良好的非牛顿流体性。
　　It effectively controls the rheology of slurry,with good non-Newtonian fluid performance.
此外，“金标”CMC用做固井液，可阻止流体进入孔隙及裂缝；用做压裂液可控制流体进入油井中去的损失。
Moreover, "Jinbiao" CMC can be used as well fixing liquor to prevent fluid entering terrane or crack, and also can be used as pressing liquor to control the loss of fluid into oil well structure.
