AutoCAD系统在清绘地质图方面的开发与应用

DEVELOPMENT AND APPLICATION OF CAD SYSTEM IN DRAWING GEOLOGIC MAP

应用AutoCAD系统在微机上开发出了清绘地质图件的CAD系统.该系统由图形输入、图形数据处理、图形编辑和图形输出四个部分组成.其中.图形输入和图形数据处理由高级语言编制而成.图形编辑和图形输出由AutoCAD完成.具有完整的高级语言与AutoCAD的接口程序.该系统的突出特点是功能齐全、精度高、速度快、使用方便.清绘出来的图件.线条平滑、流畅.精度高.能够反映油田地层,沉积、构造、储层、流体和油藏等各方面的复杂地质问题,符合地质制图规范.反映地质人员思想.能满足生产和科研的需要.

The CAD system in drawing geologic map is composed of four parts: input, data processing, edit and output. The input and processing are written in a high-level language, the edit and output is made by AutoCAD software. There is excellent interface between the high-level language and AutoCAD. The features of this system are versatile functions, high precision, fast speed, convenient modification, use and operation. The map drawn by this system has smooth curves, high precision, and can reflect all kinds of geologic information in stratigraphy, deposition, structure, reservoir and fluid. The map meets therequirement of geologic drawing, and presents the idea of a geologist, so it can satisfy the needs of field work and research.
