摘要
文中针对煤矿测井设备应用,讲述经纬度在线获取和WMM模型计算磁偏角的方法,并开发软件,在电脑和安卓终端简单方便的进行经纬度获取和磁偏角计算。获取国内10个城市经纬度和全球5个经纬度点计算,并与NGDC结果比较,所开发软件计算结果正确。
Aiming at the application of equipment on measurement while drilling, the methods on latitude-longitude acquiring online and WMM model based declination calculation were presented. And software was developed to acquire latitude-longitude and calculate declination on computer and android terminal conveniently and easily. Latitude-longitudes were obtained in 10 cities in China and five latitude-longitudes points calculation were obtained around the world and the results were compared with that of NGDC. The results of software developed was correct.
