摘要

在以往的诸多电法测井数值模拟研究过程中，大多数研究均将重心放在数值模拟软件的选取以及算法的精进等部分，使得模拟的结果很难用统一的标准进行评判，并且在实际的测井过程中，电阻率值是采用真实的采集仪器获取的。为了减少软件和算法的影响，研究过程不脱离实物，本文将阐述如何将串口触摸屏等硬件与既定的ANSYS软件相结合，利用串口显示屏可自行编程以及ANSYS软件自带有限元算法特性，构建了一套虚拟的三侧向测井仪模型。实验结果表明：（1）在测量过程随着地层厚度的增加，视电阻率值不断上升；当目的层厚度高于2.00 m视电阻率值就近视于真实的地层电阻率值。（2）随着井径长度从0.2 m逐渐增大，视电阻率也随之下降。以上两项结果量化了地层厚度与井径对电法测井的影响，同时也证明了该套模型的可行性。

Abstract

In the past

many studies have focused too much on the selection of numerical simulation softwares and the refinement of the algorithms

which leads to the consequence that the simulation results are difficult to be judged with a uniform standard. And in the practice of the logging process

the resistivity value is obtained by using real acquisition instruments. To reduce the impact of software and algorithms and make the research process not divorce from the physical

this article will elaborate how to combine some hardwares just like serial port touch screen with ANSYS software

how to use the characteristics of serial port touch screen which can be programmed by itself and ANSYS own finite element algorithm to establish virtual three-lateral logging tool model. Experimental results indicate that:(1) With the increasing of formation thickness

the apparent resistivity value increases

and

while the thickness of the target layer is higher than 2.00 m

the apparent resistivity value is getting close to the true formation resistivity value gradually. (2) With the increasing of well diameter starting with 0.2 m

the apparent resistivity value decreases. Two results above quantify the influence of formation thickness and well diameter on the electrical logging and prove the feasibility of this model meanwhile.
