摘要
Near-shore underwater fan in Ningjin fractured steep slope belt is the fan-shaped glutenite body quickly accumulated by flood water and muddy flow, which has strong heterogeneity because of vertically overlaying of phases and horizontal frequently swing and moving. The key of the exploration is to accurately predict the favorable hydrocarbon bearing zone. In terms of the sedimentary characteristics and drilling data of near-shore underwater fan in the area, the authors summarized its seismic reflection features, and predict its development phases and scale by using seismic facies method. By utilizing 3D visualization and seismic attribute analysis, the middlefan subfacies was further identified. Based on the prediction result of middle-fan subfacies, combining with attribute stack method, the distribution of middle-fan subfacies and favorable hydrocarbon bearing zone of No.2 near-shore underwater fan was predicted. The well Gy33 was deployed by the above research result, and its oil production is 23.36 t/d, which proved the reliability of prediction results.
