纤维素 - 石油、天然气和矿

钻出更高的石油产量  

CELLOSIZE™羟乙基纤维素(HEC)是一系列非离子型水溶性聚合物,用于不同形式的石油生产,可增稠、悬浮、粘合、稳定、分散、形成薄膜、乳化、保留水分并提供保护胶体的作用。这些独特的材料可用于制备具有各种粘度的溶液 - 包括具有正常胶体特性的中等粘度,直到具有最少溶解固体的最大粘度。 

在修井和完井液中,CELLOSIZE™ HEC是增粘剂。它可以帮助石油生产商提供清澈、低固体含量的流体,有助于最大程度减少对地层的破坏。用HEC增稠的流体很容易被酸、酶或氧化剂破坏,以最大限度地提高烃的采收率。 

在压裂液中,HEC材料可作为支撑剂的载体。这些流体也可以很容易地用酸、酶或氧化剂分解。 

使用低固体含量概念,使用CELLOSIZE™ HEC配制的钻井液可提供更高的渗透率和更好的井眼稳定性。抑制特性的流体可用于钻探中等到硬质岩层,以及膨胀或坍塌页岩。 

在固井作业中,HEC材料降低了浆料的水力摩擦,并最大限度地减少了地层的水耗。
