RESERVOIR ARCHITECTURE OF SUDONG X DENSE WELL PATTERN ZONE IN THE LOWER PART OF SHIHEZI 8 FORMATION IN SULIGE GAS FIELD, CHINA

Taking the dense well pattern zone in the lower part of Shihezi8 formation in Sulige gas field as the research object, according to core observation and well logging facies analysis, identify the the lower part Shihezi 8 period of braided river delta sedimentary are 5 kinds of microfacies, of which the channel bar microfacies are principal. By means of single well channel bar internal architecture and multiple well profile analysis, identify the internal interface classes. Based the combination of logging curve and channel bar development pattern, we confirmed the beach boundary and then determine the channel bar sacles of six sections in Sudong X dense well pattern zone in the lower part of Shihezi8 formation in Sulige gas field.
