摘要:
百色油田百4油藏中三叠统兰木组储层主要由藻灰岩、亮晶灰岩及泥灰岩组成。后期岩溶作用对储层改造作用明显,在灰岩顶部表现为风化壳,内幕表现为缝洞。结合岩心观察成果及生产情况,认为该地区缝洞含油,以裂缝沟通流体。通过分频能量不连续性属性刻画水平缝及溶孔发育情况,利用曲率与不连续蚂蚁追踪属性融合刻画高角度裂缝,并综合单井、物探及生产认识,认为百4块潜力主要分布在构造高点,预测了缝洞发育的位置。
Abstract:
The reservoirs of the Triassic Lanmu Formation in the Bai 4 reservoir of the Baise Oilfield are mainly composed of algal limestone,sprite limestone,and marl. The later stage of karstification has an obvious effect on reservoir reconstruction,where the top of the limestone appears as a weathered crust and the inner surface appears as a fracture-cavity.Combined with the core observation results and the production situation,it is believed that the fracture-cavity in this area contains oil,and the fracture communicates the fluid. The development of horizontal fractures and dissolved pores are described by the discontinuity attributes of frequency-divided energy,and the high-angle fractures are characterized by the combination of curvature and discontinuous ant tracking attributes.Based on the knowledge of single well,geophysical prospecting,and production,it is concluded that the potential of Bai4 is mainly distributed in structural high points,which predicts the location of fractures and caves.
