The Application Of Data Fusion In The Research Of Physic Parameters Of Complicated Oil-gas Reserve

For the going-on economy development, the petroleum require is more and more in China. That makes it important to find new oil reserves and oil-gas field. Because it is more difficult and costly to reconnoiter today, the application of new theory and method to evaluate oil-gas resource has become integrant. So it is important in theory and practice that applying new technology and method in geologic reconnoiter to upgrade old oil-gas field and to find new oil-gas field. The complicacy and randomicity of geologic phenomena make it necessary to application advanced math in geologic reconnoiter to finding a new way, which can indicate the oil-gas resource, especially the oil-gas resource in complicated area.The traditional method to evaluate oil-gas resource and to find best oil-gasfield is just to overlap the figures of porosity, percolation rate, gas saturationand etc, which is often affected by different operating crew. This work is to build a new way to evaluate oil-gas resource and to find best oil-gas field by a new parameter through the data fusion based on Kalman filter. The new way can avoid the affection of operating crew, and then image the real reserve. The work shows the result by many figures, especially by the surface of fractal interpolation, to make it more intuitionistic. The practice application of this new way shows that it would evaluate the reserve more impersonal and indicate the best oil-gas field more effectual.
