Yan 9?Chang 1 Reservoir "Four" And The Logging Interpretation Model Extension ZJ Ding Bian Oilfield

The proportion of low permeability reservoirs is very large in our country,and Odors basin is China's largest oil and gas resources of low permeability reservoirs.At present,facing the condition of excessive dependence on imported oil and gas,the researchers had to overcome the problems in the study process about low porosity low permeability reservoir.Because the geological environment of this kind reservoir is complex,conventional log interpretation method is difficult to have a very good explanation result,which increases the difficulty of exploration and development of such reservoirs.These reasons lead Odors basin become the research focus.Aiming at these problems,based on the guide of the theory of sediment logy,petroleum geology,according the background of whole basin's tectonic evolution and sedimentary environment,sorting and analyzing the geological,drilling,logging and other first-line data,using geophysical,petrochemical and geological research methods,combination field geological research(field observations strata,sampling,observing core,taking pictures,etc.)and indoor geological(scanning electron microscopy seem),gong experiment,mineral analysis,etc.)in the research.Using varies methods such as cross plot,linear regression function to study the structure,sedimentary and reservoir of Yan 9 formation of Yan an group,Chang 1 formation Of Yan change group about ZJ oil region of Ding bran oilfield.
