3D Data Acquisition and Visual Emulation Research Based on Wireless Sensor Array

A data acquisition system based on wireless sensor array is used to collect underground three-dimension data in this paper. Sensors are installed in a mode of plane array, using 2D excitation source explode signal, the acquisition system can repeat receiving the data of different excitation source, and the collective data can form 3D data cube by corresponding process. The data structure of 3D data cube is analyzed and the 3D emulation model of underground oil reservoir is established. The methods of displaying slice about the 3D emulation model are studied using the technology of computer graphic and image processing. We accomplish the vertical slices of underground oil reservoir from multidirection and multiangle in this paper, in order to display clearly the structural feature of underground oil reservoir and to make the oil engineer have a clear apprehend about the underground oil reservoir overall structure. Programming the corresponding algorithm and graphic display programmes using C++. Some typical emulation images are given taking example for an underground oil reservoir of one oilfield
