随着测井技术的不断发展,贴井壁的测井仪器越来越多,对贴井壁装置即推靠器的要求也越来越高。对密度测井仪也越来越需要较高水平的推靠器。但是,生产厂家和野外油田对此研究甚少,而且不够深入。本文拟以单臂推靠器为例从力学观点作了探讨。首先对推靠器进行受力分析,并简化为受力图,从而导出力学公式,然后对影响推靠器的各种因素进行分析找出它们之间的关系及着重点,为设计出优质的推靠器提供理论依据。
With the continuous development of logging technology, there are more and more well logging instruments attached to the well wall, and the requirements on the well wall device that is pumped up are also getting higher and higher. Density logging tools are also increasingly in need of higher levels of pushers. However, manufacturers and field oil fields have little research on this, and not enough depth. This article intends to use one arm thrust device as an example from the mechanical point of view made a discussion. Firstly, the force analysis of the pusher is simplified and simplified as the force diagram to derive the mechanical formula. Then the various factors that affect the pusher are analyzed to find out the relationship between them and the important points. In order to design a high quality Pushing off to provide a theoretical basis.
