摘要
针对富满油田主干断裂间和台缘滩深层的麻坑,在对三维地震资料进行精细解释的基础上,结合富满油田钻井和地震综合解释等资料,建立了麻坑的地震地质模型,通过改变麻坑发育规模及裂缝发育密集程度等因素,模拟分析富满地区古海底麻坑的地震响应特征变化,总结并建立了富满地区麻坑的地震识别模式以及麻坑分布、成因及其油气潜力,为富满地区奥陶系古海底麻坑储集层的有效预测提供依据.
Abstract
For the pockmarks between major faults and in deep marginal-platform beaches in the Fuman oilfield,a seismic geological mod-el was established based on the detailed interpretation of 3D seismic data and the analysis of the drilling and seismic data in the oilfield.This model enabled a simulated analysis of the variations in seismic response characteristics of the ancient pockmarks in the oilfield by al-tering the factors such as pockmark scale and fracture density.Consequently,seismic-based pockmark identification models were proposed,along with an understanding of the distribution,genesis and hydrocarbon potential of the pockmarks.The study results provides a founda-tion for the effective prediction of Ordovician ancient pockmark reservoirs in the Fuman oilfield,Tarim basin.
