新开发的涂层被涂在标准绕丝筛的外侧(即面向地层),以使槽具有抗侵蚀性。该涂层由陶瓷或硬质金属组成,并通过等离子喷涂形成。进行了广泛的开发和验证计划,以保证规定的槽宽、耐腐蚀性以及涂层和筛网的机械强度。该涂层提高了抗侵蚀性,可以承受腐蚀井环境,并且具有适合安全安装在任何井中的机械性能。

A newly developed coating is put on the outside (i.e., facing the formation) of standard wire-wrapped screens to make the slots erosion-resistant. The coating consists of ceramic or hard metal and is applied by plasma spraying. An extensive development and verification program was conducted to guarantee defined slot widths, corrosion resistance, and mechanical strength of coating and screen. The coating improves resistance against erosion, can withstand corrosive well environments, and features mechanical properties suitable to be safely installed in any well.
The screens are coated using thermal spraying.
