文昌油田WC13-1/2目前处于中高含水开采期,现用缓蚀剂已无法适应油田产液量、油田综合含水、海底输油管线压力、温度、流速的变化;因此,对在用缓蚀剂进行针对性的优化势在必行。本文针对文昌油田油水性质及现场工况条件,开展静态、动态腐蚀评价实验,优化筛选出了适用于现场的缓蚀剂,现场实验证明了其具有优良的缓蚀性能;同时,建立了一套系统的层进式的缓蚀剂筛选方法,为海底输油管线的腐蚀防护提供了有力的技术支持。
Wenchang Oilfield WC13-1 / 2 is currently in the mid-high water cut period, the existing corrosion inhibitor has been unable to adapt to the oil field liquid production, oilfield integrated water, seafloor pipeline pressure, temperature, flow rate changes; Therefore, Targeted optimization is imperative. In this paper, according to the nature of oil and water in Wenchang Oilfield and the working conditions of the site, static and dynamic corrosion evaluation experiments are carried out to optimize the corrosion inhibitors for the site. Field experiments show that the corrosion inhibitors have excellent corrosion inhibition performance. Meanwhile, a set of The systematic layer-by-layer corrosion inhibitor screening method provides strong technical support for the corrosion protection of submarine oil pipeline.
