Dynamic Compression Method: Tests On Caykinskaia Field Data

摘要

The ambiguity in the interpretation of seismic image for the most part caused by interference of the reflected waves and the frequency characteristics of the recording. These factors limit the time resolution of the wave image and detalisation of complex geological objects. Increase time resolution using frequency filtering is often not the optimal solution. This paper will discuss the method of Dynamic compression (DC) - one of the way of time domain deconvolution. This method allow increase the time resolution of section by the multi-iterative algorithms of wavelet subtraction. In the result, classic seismic image transformed into the distribution of delta functions. New DC image reflects more accurately the structure of the seismic boundaries and internal features of layers. For the testing of DC method, we used seismic data from Chaykinskaia field. Quality control based on drilling and logging data
