摘要:
 过油管打塞作业所形成的水泥塞长度较短，造成可靠性差、密封性不好，施工成功率相对较低。根据水泥塞封堵高压的原理，分析影响水泥塞胶结强度的诸多因素，以及造成施工成功率低的原因，通过配套使用膨胀式水泥和套管清洁剂，有效地改善了过油管打灰作业的封堵能力、可靠性，提高了作业成功率。在某国东部油田67口井的应用，成功率由895%提高到985%。该技术改进有效可靠，具有一定的市场前景和推广价值。
Abstract:
 The length of the cement plug formed by the plugging operation through tubing is relatively short, resulting in poor reliability,〖JP2〗 poor sealing, and relatively low operating success rate. According to the principle of the high pressure of the cement plug, the influencing〖JP〗 factors on the cementing strength of the cement plug and the reasons for the low operating success rate were analyzed. The combined use of expandable cement and casing cleaner can effectively improve the sealing ability, reliability and the success rate of the operation. The improved technology has been applied to 67 wells in an eastern oilfield in some country, and the success rate has been increased from 895% to 985%. The technology improvement is effective and reliable with certain market prospects and promotion value.
