Feasibility and Adaptability of a New Algorithm of Neural Network to the Calculation of Reservoir Parameters;

The lithology of deep wells in eastern Daqing oil field and complex,so calculating reservoir parameters and recognizing fluid are very difficult.

To estimate ERP parameters, two different ways are involved: one is the parameter transformation, the other is direct adjustment method with restrictive conditions.

For the geometry matching search that appeared in the product configuration design based on case reasoning,the similarity model of geometric attributes denoted in the different ways was put forward,the objective function about parameter transformation was constructed by using the principle of least squares,the 6 unknown variables were solved by adopting the algorithm of bound constraint BFGS.

Using RTK to solve WGS-84 and the discussion of coordinates with the city of transformation parameters

This paper studied and solved the key problems of connection survey,determination of transformation parameters,programming of transformation softw.

If the transformation parameters are solved with the GPS data in a small area,the precision of transformation parameters may be very poor,especially the translation parameters.
