振动固井电力振动器激振力和振幅分析
|
摘要
为了使水泥浆在候凝阶段产生振动,提高固井质量和界面胶结强度,研制了一种固井电力振动器。该振动器通过高温电池组提供电能,带动高温电机产生振动,安装在管柱的底端,不会改变常规固井工艺。通过结构设计和力学分析,对该工具的激振力进行了计算,其最大激振力为1 732 N。运用能量法,结合某井的参数,对该工具在安装有弹性扶正器的直井套管产生的振幅进行了分析,得出了其在弹性扶正器处产生的振幅计算模型,为井下振动固井工具的现场试验提供了理论指导。
In order to make the cement slurry generate vibration in the phase of waiting on cement, and thus improve the cementing quality and interface cementing strength, an electric vibrator was developed. This vibrator is provided with power by a high-temperature battery to allow the high-temperature motor to generate vibration. It is fitted at the end of the string. Thus, the conventional cementing technique would not be changed. The exciting force of the vibrator was calculated as 1 732 N based on configuration design and mechanical analysis. With the energy approach and the parameters of a well, the amplitude of the vibrator generated in the vertical well casing where elastic centralizer was installed was analyzed and calculated, thereby providing theoretical guidance for the field test of vibration cementing tools.
