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.

Taking intermittent test production well as studied objective, by arranging former test production data and using initial producing data acquired at intermittent process, formation parameters at two stages of testing and intermittent test production periods for natural potential and reformed wells are compared and analyzed and forecasting method is studied.

In addition, the important forms used to calculate the formation parameters, such as shale volume, water saturation and permeability, are improved to be more suitable for the calculation of inhomogeneous formation parameters according to the power law of fract.

The problem in testing analysis, such as longer closed-in time, multi-answers of interpretation and low-permeable formation parameters which can not be obtained by conventional well testing ways, have been solved through the applica.

Influence analysis and application of reservoir parameters from fracturing well on incremental result;

Results show that both Fetkovich and Blasingame decline curves are more available for predicting formation parameters for the low-permeability gas wells or some gas wells which can\'t be shut-in for a long time.
