该反应产物可用于水基钻井泥浆，用于钻井和/或完井油井。该添加剂即使在高温高压条件下也具有减少滤液的特征功能; 此外，它适用于在盐和固体存在下的应用。 在现代钻井技术中，钻井液需要履行许多不同的作用，例如压力控制。钻头的润滑和冷却，从下颚位置切除切割并防止井喷。然而，深井钻井可能会遇到高度复杂的问题。有时，与钻井液损失有关的危险问题。尽管这些损失主要是由于钻井液被渗透的地质构造的结构条件，但是在钻井液配方中使用的具有水泥材料的降滤失剂添加剂可能在解决该问题中起重要作用。由于在石油勘探中遇到越来越严苛的条件，因此希望改善水基钻井液的常规润滑作用以减少能量耗散和钻柱磨损。 滤液减速器用于减少由钻井液的液相引起的地层的流体损失。The product of the reaction useful in water-based drilling muds which are employed in the drilling and/or completion of oil wells. The additive exhibits its characteristic function of filtrate reduction even at high temperature and pressure conditions; and, moreover, it is suitable for application in the presence of salts and solids. In modern drilling technology drilling fluids are required to fulfill many different roles, such as pressure control. lubrication and cooling of the drill bit, removal of cutting from downholc locations and prevention of blowout. However the drilling of deep wells may meet highly complex and. sometimes, hazardous problems related to loss of drilling fluids. Although these losses are due mainly to the structural conditions of the geological formations drilling fluids are penetrated, filtrate reducer additive with cement material used in drilling fluid formulations may play an important role in the solution to this problem. Owing to increasingly severe conditions are encountered in oil exploration it is desirable to improve the conventional lubricating action of water-based drilling fluid for reducing energy dissipation and drillstring wear.
