详细说明

铬木素磺酸盐

  铬木素磺酸盐,是利用亚硫酸法废液或木质素磺酸钙、木质素磺酸钠等为主要原料,经氧化、络合等一系列反应,精制而成。产品外观为棕褐色粉末,易溶于水,水溶液呈弱酸性,使得其分子量较铁铬木素磺酸盐的分子量更为适合钻井泥浆的降粘工艺,同时产品中铁含量小于0.8%,避免铁离子对油井的污染,因此铬木素是一种性能与铁铬盐相近或(稍好),而又对油井污染少的泥浆降粘剂。

  铬木素磺酸盐既有降失水作用,又有稀释作用,同时还具有抗盐、抗高温、配伍性好的特点,是一种抗盐、抗钙和抗高温能力强的稀释剂。产品广泛应用于淡水、海水、和饱和盐水泥浆,各种钙处理泥浆和超深水泥浆,有效地稳定井壁和使泥浆降粘、降切作用。

Chrome lignosulfonate 

  Chrome lignosulfonate is a kind of main raw material,base of sulfite pulp waste law,or calcium lignin sulfonate,lignin sulfonate,etc.by oxidation,and a series of complex reactions crafted.Appearance of brown powder,soluble in water,aqueous solution was slightly acidic.Makes the molecular weight bigger than the Fe-Cr-molecular weight of lignin sulfonate 0.8%,to avoid the iron ion pairs of wells contaminated,lignin is a kind of chromium and iron chromium salts similar to or(slightly better),mud viscosity reducer,less pollution on oil.

 

  Chrome lignosulfonate can not only reduce water effect,but also dilution effect,and also has features of salt-resistant,anti-high temperature,good compatibility.It is akind of salt-resistant,anti-calcium and anti-temperature and ability of the diluents.The products are widely used in freshwater,seawater,and saturated salt mud,all kinds of calcium handling and ultra-deep mud wall with a effective way to stabilize and to make mud viscosity reduction,reduce cutting action.
