越南的一家海上运营商在亚静压和高芳香烃气井中面临高产水量。除了生产率低之外,高含水率还给水处理设施带来了压力。由于井况严峻,之前尝试关闭高产水区的处理措施均未成功。经过广泛的实验室测试,发现使用触变有机交联聚合物 (TOCP) 的定制解决方案是该井最合适的处理设计。

Water Shutoff With a Thixotropic Treatment in Offshore Well Increases Gas Production

This paper describes a customized solution using a thixotropic organically crosslinked polymer as a treatment design for a subhydrostatic and highly aromatic offshore gas well.

Use of RPM. Hydrophobic modifications allow the polymer to build up on the rock surface.

An offshore operator in Vietnam faced high water production in a subhydrostatic and highly aromatic gas well. In addition to low productivity, the high water cut also strained the water-treatment facility. Previous treatment attempts to shut off the high-water-producing zones have been unsuccessful because of challenging well conditions. A customized solution using a thixotropic organically crosslinked polymer (TOCP) with extensive laboratory testing was found to be the most suitable treatment design for this well.
