庆新油田葡萄花油藏主控因素研究
|
摘要
本文研究工区——卫星油田,自20世纪90年代末开发至今,油藏规模越来越小,油水关系日趋复杂,严重制约着剩余储量的动用,有必要开展该区块的油水主控因素精细研究。本文以地球物理学及石油地质学为理论基础,综合应用层序地层学、沉积学及构造地质学的理论和方法,在工区的地震剖面、测井曲线形态、录井和岩芯等资料的精细描述基础上,根据各级层序界面的发育特征、追踪对比,建立层序地层格架。在建立的等时层序地层格架内,根据单井相和骨干连井剖面的分析,分层研究沉积微相和砂体展布,揭示沉积体系的时、空演化规律。研究表明,该地区葡萄花油层组沉积主要由大庆长垣延伸过来的三角洲和从安达方向延伸过来的三角洲复合体构成,存在三角洲分流平原亚相和三角洲内前缘亚相沉积。根据研究区断层与成藏的同期性、断层发育的规模性、方向性、其次性、断层与储层发育的相关性及断层对油藏类型的控制性六个角度,遵循“动用区找规律、空白区看潜力”的研究分析方法,对本区成藏有了更深刻的认识,指出该区块成藏的主控因素主要为东西向断层起到封挡作用、南北向断层则多为油气运移通道,主要成藏类型为断层——岩性油藏、断层——构造油藏、断块油藏及岩性油藏,并在此基础上合理地预测出卫星油田葡萄花油藏的有利区块。
Since the late 1990s, Weixing oil field, the work area we studied in this thesis, the reservoir scale is becoming smaller and smaller, oil-water distribution is getting more and more complicated, which constrain the use of remaining reserves seriously, we make a study of the main controlling factors of the interest block are necessary.Based on the detail descriptions on seismic profiles, logging curve features, logging and core datas of the work area and according to the sedimentary characteristics and tracing comparision of various sequence interfaces, we establish sequence stratigraphic framework by taking Geophysics and the Petroleum Geology as theoretical basis and applying sequence stratigraphy, sedimentology and tectonic geology theories and methods comprehensively in this thesis. In the established chronostratigraphic sequence framework, we study sedimentary microfacies and sand distribution, and reveal the space and time evolution regularities of sedimentary system on the basis of analysis of single well facies and well-connecting profiles of skeleton wells. As is shown in the research, the deposits of Putaohua reservoir in this area mainly consist of complex delta extended from Daqing placanticline and Anda direction, which exist distributary plain facies and delta front facies. Seeing from six aspects in the synchroneity among faults and reservoir sedimentation, the scale, direction, subsequence features of fault development, the development correlation between fault and reservoir, the controlling ability of faults to reservoir types, following the studied analysis method—“finding rules in working area, finding potential in blank area”, we get a deep knowledge of this area, and point the main controlling factors of this block out. That is, the east-west faults play the role in accumulating, while the north-south faults play the role as migration pathway.The main sedimentation types are fault-lithologic reservoir, fault-sectonic reservoir, fault block reservoir and lithologic reservoir. Based on these, we can predict the profitable exploration areas of Putaohua reservoir of Weixing oil field reasonably.
