Article Preview

For rocks complexity, geologic drilling is a high cost project, and it is high risk. Drill monitor is an important tool in monitoring drilling, scientific analysis and decision. It can continuously monitor drilling process, identify and forecast abnormal operation modes. It is the key means to reduce drilling accidents and ensure high efficiency, high quality and low cost. This paper analyzed some problems of domestic drill monitor based on the research status on drill monitor at home and abroad. Author considered all hydraulic core drilling rig with 2000m drilling capacity as research object, and modularly designed multi-drilling-parameter data acquisition system according to the geologic exploration own characteristics. This system can identify typical drilling operation modes used data handling techniques of wavelet analysis and time series analysis. With implement of state geology investigation strategy, drilling workload increase greatly, drilling depth increase continuously, and the drill monitor has a very wide application prospect.
