整体式半刚性扶正器、整体式弹性扶正器的研制与应用

Development and Application of Integral Semi-Rigid Centralizer and Integral Elastic Centralizer

在油田开发过程中,应用套管扶正器是提高水平井、大斜度井套管居中度的重要技术措施。针对常用套管扶正器使用过程中存在的问题,急需研制出操作简单、扶正效果好的整体式半刚性扶正器和整体式弹性扶正器。通过扶正器技术分析、技术参数制定、材料优选、加工工艺分析和单件试制、室内评价实验及固井现场实验的有效开展,使得各项技术达到相关标准设计要求,从而有效解决了相关技术难题,具有很好的应用前景。

In the process of oilfield development, the application of casing stiffener is still an important technical measure to improve the middle of the horizontal well and large gradient well casing.Aiming at the problems in the process of using the conventional casing centralizer, it is urgent to develop a monolithic semi-rigid centralizer and a monolithic elastic centralizer with simple operation and good righting effect.Through the technical analysis of the centralizer, the technical parameters, the optimization of the materials, the analysis of the processing technology and the single-piece trial, the indoor evaluation test and the effective development of the cementing field test, so that the technology meets the relevant standard design requirements, so as to effectively solve the relevant technical problems, Has a good application prospects.
