Research On Individual Sand Body Architecture And Remaining Oil Of YⅠ Thick Sandstone In Long Core Horizontal Well Block Of East 14th

At present, the domestic majority of oil fields entered the development mid and late part, along with development unceasingly thorough, seeking for and tapping latent potentialities the remaining oil with the reasonable effective method appears especially important. The development reservoir fine description, the internal sandbody architecture and the internal flow unit research, and then remaining oil distribution rule analysis, helps for the oil field adjustment development program and the production increase picks provides the advantageous basis .This thesis adopts the fine reservoir sedimentology theory, has carried on horizontal core homing and the fine description, high resolution sequence stratigraphy of vertical well and earthquake in well field, surface sediment microfacies, reservoir distribution in space studies of YI thick sandstone of east 14 horizontal well block in Yushulin oil field .Based on this, regarding channel sandstone of meandering channel bar, there are horizontal well in which carries on the internal sandbody architecture studies. That revealed more complex reservoir internal architecture, reflected very strong reservoir heterogeneity for tertiary recovery stage, which has entered the high watery time, the multiple well pattern thickening .Combined with remaining oil research in subject reservoir, this paper sumed up distribution feature of reservoir remaining oil, brought vital practical significance for the continuate and highly effective development oil field and oil recovery enhancment .
