【摘要】 针对K1区块构造复杂,断裂发育,石炭系砂岩平面变化较快,砂泥岩互层,单砂体厚度较薄,地震资料分辨率低等储层预测难点,文章从地震地质特征入手,利用三维地震资料的精细构造解释,以约束稀疏脉冲反演和随机地震反演相结合为主要手段,揭示了卡拉沙依组沉积砂体的厚度及平面展布特征,为石炭系储层油气藏研究提供可靠依据。更多还原

【Abstract】 Focusing on the complex structure and developed fracture of K1 block,rapid change in the flat of Carboniferous sandstones,sandy mudstone,the thinner thickness of single sandstone,low-resolution seismic data,and other difficult points of reservoir prediction,the paper starts from the seismic and geological characteristics,using detailed structural interpretation of the three-dimensional seismic data and then combining the constrained sparse spike inversion with stochastic seismic inversion as the main means and reveals the characteristics of the thickness of sedimentary sandstone and plane distribution in Kalashayi group,which provides a reliable basis for Carboniferous reservoir study.更多还原
