An exact reservoir evaluation method with gray theory and its application to log interpretation of horizontal well are illustrated. The evaluating parameters for Well Saiping 1 are studied and the norm of each evaluation parameter is determined statistically. The corresponding plotting and display software is also developed. Displayed intuitively are the slope depth, vertical depth, horizontal displacement, slope thickness, vertical thickness of the formation drilled by the horizontal well and the geological parameters of the reservoir. The interpretation result shows the reservoir location in 3Ds and the changes of its lithology, physical properties, oil bearing properties along the borehole. And the reservoir characteristics and its heterogeneous variation law are provided, which can not be obtained from vertical well.

An approach for reservoir evaluation in Chengdao Oilfield using logging multiparameter technique and grey scale theory is presented in the paper. It begins with a calculation step for the evaluation index of each formation based on log data, which is then correlated with strip log,geological data and data from potential test to statistically determine the criterion for reservoir evaluation and the weight for each index. In this way, the cigenvalue of each scale in a grey system is determined and presently employed...

An approach for reservoir evaluation in Chengdao Oilfield using logging multiparameter technique and grey scale theory is presented in the paper. It begins with a calculation step for the evaluation index of each formation based on log data, which is then correlated with strip log,geological data and data from potential test to statistically determine the criterion for reservoir evaluation and the weight for each index. In this way, the cigenvalue of each scale in a grey system is determined and presently employed to whiten the grey system, based on which the prediction for stratigraphic lithology, reservoir parameters, and the hydrocarbon potential is able to be brought about. A program written for the above method has been applied to the data from segments about 4700m in total in 10 odd wells in Chengdao Oilfield. The result is shown to match the core data, the data from potential test, and geological analyses on the whole. Everything regarding the approach is detailed in the paper.
