Regional well-site data monitoring is of great significance to the control and decision-making of the geological drilling process. To solve the problems of sing well-site data， poor data interconnection， and lack of remote portable monitoring software in most current condition monitoring systems for the geological drilling process， a condition monitoring App based on Android for geological drilling process has been developed in combination with mobile communication and Internet technology. The App is designed with Model-View-Presenter architecture as a whole and has a series of functions such as real-time monitoring， historical curve trend analysis， and so on. It has been used on a geological drilling site and achieved good condition monitoring effect. The App can obtain the real-time status information of the drilling process and timely remind experts to make operation adjustments and decision-making， which provides great convenience for geological drilling.
