Application of Deconvolution Well Test Interpretation Methods in East China Sea Oil and Gas Fields

Due to short test time of offshore oil and gas wells,it is very difficult to use the conventional well test interpretation methods to reflect accurately the characteristics of formation boundary.By using the deconvolution algorithm for well test interpretation,with long pressure history of production for analyzing well testing on the basis of superposition principle,long time test pressure response can be obtained.This can provide more information about reservoirs and reliable basis for identification of reservoir boundary,being complement and improvement for the unstable well test interpretation method.By using the deconvolution method,with limited oil and gas well test data of the East China Sea,the application results have been summed up.The deconvolution method has important value for exploration and development in East China Sea.
