Study On The Invertsion And Application Technology Of Logging Curves' Vectorization

Logging curve is the precious wealth of the oil field, which is left in the process of exploitation.during the exploratory development, Logging curves that reflect the feature of petrographic and sedimentary environment and so on,is the essential information , referring to which,we can know reservoir's physical feature and its spatial distribution rule,at the same time ,it is also an important approach to strata contrast,dividing thickness,interpreting reservoir's parameters,predicting sand body's distribution and accurate geologic description. AS the developing of the new technique of the exploration, Logging curve is long-term reliable information. However,many curves,so far,are described in the blue print,which are hard to save and use,what was worse, partly horizontal axis of them are subjected to serious damage.so we must adopt information technology to save the curves forever so that we can use them further.we do study on the technique of logging curves'vectorization in terms of correlate technological documents and research results of home and abroad, aiming at saving the logging curves in computer compressly and digitizating them for further application.we have some autonomy techniques as follows: compressing of the logging curves, Tracking and refining technology, logging curves'vectorization and correction,logging curves'vectorization and saving and designing data sharing program.we applied our research to the Sazhong district,it not only can improve the methods and techniques of the images'vectorization,but aslo get ready for accurate geologic research.besides,this research has a wide range of promotional value.
