JJX型井斜仪,是目前使用较广的电测井斜的仪器之一.这一仪器常因电桥失谐而产生故障,而电桥失谐是由于长期使用中,受外界物理条件的变化,影响到电桥参数的改变所致.因此,处理这类故障,就不能用更换备用的灵敏元件及其度盘的办法去解决,而应从根本上,即对电桥进行调节,以求得较彻底的解决(图1).要寻求电桥的合理调节方法,必先清楚地了解仪器中电桥的结构,并找出电桥测量臂与其它臂间的函数关系.
JJX-type inclinometer is one of the widely used inclinometers for electrical logging, which often causes faults due to the detuning of the bridge, and the bridge detuning is due to the long-term use under the influence of external physical conditions Change, affecting the change of the bridge parameters.Therefore, to deal with such failures, we can not replace the spare sensitive components and its method of dial to solve, but should fundamentally, that is, to adjust the bridge in order to A more thorough solution (Figure 1) To find a reasonable way to adjust the bridge, we must first clearly understand the structure of the bridge in the instrument, and find out the bridge between the measuring arm and the other arm function.
