在地应力资料的分析研究中,必须设法确定探头在井下工作时的实际灵敏度。本文从实测资料出发,根据四分向探头在接收到应力变化信息时,其相互间的关系应符合互校原理这一物理基础,利用牛顿法解非线性方程组来估计探头实际灵敏度校正系数。经用琼中台的资料进行实际试算,得到了较好的结果 In the analysis of geostress data, we must try to determine the actual sensitivity of the probe when working downhole. In this paper, based on the measured data, according to the quadrupole probe received stress change information, their mutual relationship should be consistent with the mutual proof principle of the physical basis, the use of Newton’s solution to nonlinear equations to estimate the actual sensitivity of the probe correction factor. The data from Qiongzhongtai was used to do the actual test, and the better result was obtained
