【摘要】 储层横向预测的关键是波阻抗反演,各种基础资料品质的好坏直接影响反演精度。在构造解释成果基础上,结合该地区的地质状况和地震资料对储层进行基于模型波阻抗反演,以波阻抗反演得到的砂体分布范围为依据,对泉一段进行横向预测研究。结合沉积相分析成果,为寻找有利目标奠定了基础,建立一套沉积相-地震储层预测-地震地质解释三位一体的隐蔽油气藏勘探开发新思路。更多还原

【Abstract】 As the acoustic impedance inversion is the key of lateral prediction of reservoirs,its accuracy is directly influenced by the quality of basic data.Based on the results of the structure interpretation,this paper firstly combines the geological conditions and seismic data of FIQ area,and conducts acoustic impedance inversion over the reservoirs.And then taking the distribution range of sand body in the impedance inversion as the foundation,it predicts the horizontal distribution of reservoir in the Quanyiduan.Combined with the results of sedimentary facies analysis,this paper finally establishes a set of new ideas of subtle reservoir exploration and development-the trinity of sedimentary facies,seismic reservoir prediction and seismic geological interpretation so that a preparation for seeking the interest zones would be made.更多还原
