基于SVG的油田井位图发布系统.doc

摘 要 基于SVG的油田井位图发布系统的是开发井数据库项目中的一个重要的模块，目的是在SVG格式的油井分布图中轻松的实现大量井位数据的动态加载；进而利用SVG图形的特性方便的实现井位信息的定位和利用。 本文主要是在B/S模式下利用SVG(Scalable Vector Graphics可升级矢量图像)和Javascript技术实现油田坐标系统中大量井位信息的动态、快速加载，方便用户对井位坐标信息的查找及利用 首先利用SVG建立某一地区的油田坐标信息描绘，然后从数据库中抽取该地区所有油井的井位坐标信息，并通过某种的方式将这些井位信息绘制到SVG地图中；通过SVG地图放大、缩小、移动、查找文字等功能实现井位信息的查询。然后利用数据库技术实现大量井位数据的动态加载，需要加载的数据信息包括油井的坐标、类型、所属单位等相关信息。完成后能够使用户以浏览器的方式打开井位图并对地图上的元素进行操作。 关键词：油田井位图；动态加载；B/S模式；SVG；Javascript Abstract oil field well position chart issued the system Based on the SVG is develops in the well database project an important module, the goal is in the SVG form oil well distribution map the relaxed realization massive well position data dynamic load; Then uses the SVG graph the characteristic convenience realization well position information localization and the use. This article mainly is (Scalable Vector Graphics may promote vector image) under the B/S pattern using SVG and in the Javascript technology realization oil field coordinates system the massive well position information tendency, the fast load, convenient user to well position coordinates information search and use First establishes some local using SVG the oil field coordinates information description, then extracts this local all oil wells from the database the well position coordinates information, and draws up through some way these well position information in the SVG map; Enlarges, functions and so on reduction, migration, search writing through the SVG map realizes the well position information inquiry. Then the use data bank technology realization massive well position data dynamic load, needs to load data message including oil well coordinates, type, subordinate unit and so on related information.After completes can cause the user to open the well position chart by the browser way and to carry on the operation to on the map element. Key words: Oil field well position chart; Dynamic load；B/S Mode；SVG；Javascript 目 录 第1章 概述……………………………………………………………… 1.1井位加载………………………………
