乌尔逊凹陷乌东斜坡南屯组沉积相及有利储集相带
SEDIMENTARY FACIES AND FAVORABLE RESERVOIR FACIES BELTS OF LOWER ZUUNBAYAN FORMATION IN WUDONG SLOPE IN WUERXUN SAG
摘要
Abstract
Based on the core analysis and combined with the analyses of log facies, seismic facies and seismic attribute extraction, fan-delta and shallow and semi-deep lacustrine sedimentations have been identified in Lower Zuunbayan Formation. The development and distribution of sedimentary facies and microfacies have been revealed in the sequence stratigraphy framework with high-accuracy, and the main source direction is the uplift areas in the east and northeast of the slope. Four types of development patterns of the favorable reservoir facies belts in this block have been established: structural-lithologic trap formed by fan-delta front sand bodies in highstand and lowstand system tracts in faulted slope-break zone; truncated unconformity trap formed by fan-delta front sand bodies in highstand system tract under sequence interface; lithologic trap formed by incised valley in lowstand system tract; onlap unconformity trap formed by fan-delta front sand bodies in lowstand system tract. All of theye providea reliable evidence for the exploration and development of this block.关键词
