摘要:
磨损和腐蚀是导致套管失效的主要因素。基于对套管磨损的理论分析,预测套管在钻进中的磨损量及油田开采周期内对套管壁厚的腐蚀量,结合套管强度校核,研究基于磨损作用的套管腐蚀对套管选型的影响。研究结果表明:磨损可使腐蚀速率增加,从而使套管管壁上的腐蚀坑深度增加,所以磨损和腐蚀因素与所用套管的壁厚具有相关性。在套管设计和选型时应对其磨损和腐蚀情况进行分析和计算,并确定所用套管的公称重量。
Abstract:
Wear and corrosion are the most common causes of casing failure. Based on the theoretical analysis of casing wear, the amount of casing wear in the drilling and corrosion of casing wall thickness in oilfield production expire are predicted. In combination with casing stress check, the effect of casing corrosion on the casing selection with consideration of wear effect is studied. The results show that the wear can lead to the increase of corrosion rate, the corrosion pit depth on the casing wall is increased, so the wear and corrosion are related to the wall thickness of the casing used. Both wear and corrosion of casing should be analyzed and calculated in the design and selection of casing as well as to determine the nominal weight of the casing.
