渤南洼陷沙三段浊积水道砂岩油藏相控储层预测
|
摘要
常用的稀疏脉冲、基于模型的井约束地震以及地质岩性随机模拟等储层反演方法,在浊积水道砂体勘探中的储层预测效果不理想。利用相控储层预测技术,结合古地貌分析成果、已开发井区资料,以高精度地震资料为手段对渤南洼陷沙三段浊积水道砂岩进行了储层预测和岩性圈闭评价。结果表明,在单斜构造背景及构造等值线、断层走向线、油水边界线"三线"平行或低角度斜交环境中,渤南洼陷沙三段浊积水道是浊积岩油气勘探的有利相带。在同一水道砂体的不同位置,由于断层封堵性的差异,圈闭及成藏条件存在较大变化,可以形成"切香肠"式的构造-岩性圈闭油藏。该类油藏高部位含水并不能说明低部位不含油,因此在该类油藏的勘探过程中还需对断层封闭性进行探讨。通过勘探实践,总结出了浊积水道油藏"定位"、"寻源"、"跟踪"、"比对"的勘探经验,同时证明了相控储层预测技术是高成熟探区精细勘探中行之有效的方法。
Inversion techniques such as sparse pulse inversion,well-constrained seismic inversion,and geological lithology random simulating inversion were not very efficiently in exploration of the turbidity channel sandstone.Faces-controlling reservoir prediction was introduced on the basis of paleogeomorphology,high precision seismic data and exploratory development information,to predict reservoir and evaluate lithologic traps in exploration of such kind of sandstone in Bonan subsag.The results show that in such a condition of monoclinal structure,with parallelism or low angle oblique crossing of structure isoline,fault trend line and oil-water boundary line as Es3 in Bonan sag,turbidity channel is a favorable face belt for exploration of hydrocarbon.Trapping and reservoiring conditions can change greatly even in different sites of the same channel sand body for the difference of fault closed characteristics,and thus can cause to form a special structure-lithologic trap of "sausage-cut" like.Oil may accumulate in downstructure location while water existing in structural high location in the traps,so fault sealing characteristics should be taken into account in exploring of the traps.Experiences of "orienting", "searching source ","tracking","comparing" were set up in exploration of the turbidity channel sandstone reservoir.Faces-controlling reservoir prediction has been proved to be an effective method for precise exploration in high maturity explored areas.
