摘要
南堡油田古生界碳酸盐岩古潜山油藏为孔隙-裂缝型双重介质油藏。精细描述裂缝发育和分布规律,是提高油气藏勘探效果的关键。为此,在岩心描述裂缝和成像测井描述裂缝的约束下,应用叠前地震属性解释描述预测裂缝技术,确定目标区块裂缝密度、产状、发育程度及空间分布。预测结果显示,现有高产井正位于预测构造裂缝发育部位,利用该成果部署新探井,预期将获得良好勘探效果。
Paleozoic carbonate buried hill reservoir in Nanpu oilfield is a pore-fracture dual media reservoir.Fine description of fracture development and distribution is the key of improving exploration result.Therefore,with the restriction of core fracture description and image logging fracture description,prestack seismic attribute interpretation is used to prognose fractures,determine the density,occurrence,development degree,and spatial distribution of fractures in target block.The result shows that existing prolific wells just lie on the predicted locations where structural fractures were developed.Arranging new exploration wells by using this achievement is expected to be successful.
