摘要:
渤海BZ28油田为下古生界潜山裂缝性油气藏,各井钻遇碳酸盐岩储层厚度0~350 m。针对油田储层展布认识不清、单井厚度差异大、生产动静态矛盾等突出问题,综合录井岩屑、岩心观察、岩石薄片、岩矿分析、非常规测井(成像测井、核磁测井)及三维地震资料,总结古潜山碳酸盐岩裂缝性储层发育机制及地质模式。结果表明:平面上,白云岩发育区带决定优质碳酸盐岩储层展布范围;垂向上,下油组地层主要为内幕溶蚀型储层,上油组地层主要为风化壳岩溶型储层。在此基础上应用Petrel软件建立双孔介质储层地质模型。该研究成果可为28-1油田及其他相似油田的开发方案调整及挖潜提供更可靠的地质基础。
Abstract:
The BZ28 Oilfield in Bohai Sea is a buried-hill fractured oil and gas reservoir in the Lower Paleozoic,where the thickness of carbonate reservoirs drilled in each well is from 0 m to 350 m.Aiming at outstanding problems such as unclear understanding of reservoir distribution in oilfields,large differences in single well thickness,and contradiction between production dynamics and statics,the development mechanism and geological model of fractured carbonate reservoirs in ancient buried hills are summarized according to comprehensive logging cuttings,core observations,rock thin sections,rock and mineral analysis,unconventional logging(imaging logging, nuclear magnetic logging)and 3D seismic data.The results show that on the plane,the dolomite development zone controls the distribution range of high-quality carbonate reservoirs; vertically upward, the lower oil group is mainly an inner dissolution reservoir,and the upper oil group is mainly a weathered crust karst reservoir.On this basis,Petrel software is used to establish a dual-porous medium reservoir geological model.The research results can provide a more reliable geological basis for the adjustment of development plans and potential tapping of the 28-1 Oilfield and other similar oilfields.
