FACIES DISTRIBUTION PATTERN OF DAMOGUAIHE FORMATION IN TARBELL DEPRESSION

Facies analysis had been carried out in the Tarbell Depression based on lithology, logging curves and sedimentary microfacies. Various depositional systems, such as the fan-delta, delta, lake floor fan and lacustrine systems were observed in the Damoguaihe Formation. According to seismic attributes, sandstone percentage, heavy minerals etc., preliminary prediction of the distribution pattern of the depositional systems was made. The results have been proved helpful in further research on reservoir characteristics and distribution, oil and gas accumulation, traps forming in the Damoguaihe Formation and paved the way for further exploration and development of oil and gas.
