用生物聚合物XC解决水平井系列问题

USINGT BIOPOLYMER XC RESOLVING A SERIES OF PROBLEMS OF HORIZONTAL WELL

生物聚合物XC的特殊三级结构使它能够协调解决水平井施工中所遇到的一系列问题。XC的长链状双螺旋结构使其具有减阻作用,使钻井液在水平段始终处于紊流状态,阻止了水平段岩屑床的形成;XC的双螺旋结构之间依靠微弱的作用力形成网状立体结构使其具有高剪切稀释特性,这有利于大井眼段的携砂和地面岩屑的清除;XC与其它添加剂的配伍性有效解决了井眼润滑和抑制作用;XC的生物降解性保护了油层和环境;因此,XC是一种多功能处理剂。

Biopolymer XC owns a singularity three grades composition which can resolve a series of problems occured during horizontal well drilling. Because of long chain couple helix composition of XC, XC can drag reduction, make drilling fluid keep disturbed flow condition in horizontal section, and stop cutting bed formation. XC has the character of good shear thinning, it makes for prop-carrying in big hole and cuttings cleaning in surface. The compatibility of XC with other additives resolves efficiently lubricantion and inhibiting effect in horizontal well, besides, its good biodegradability cab protect reservoir and environment. So, XC is a multifunction additive.
