波阻抗约束下的测井信息在储集层岩相随机建模中的应用
|
摘要
在井距较大、完钻井较少的砂泥岩储集层岩相表征中,采用多级建模思路,充分利用地震和测井信息,首先根据波阻抗数据与自然伽马、自然电位之间的相关关系,以地震资料为约束,利用同位协同克里金模拟方法,模拟自然伽马场和自然电位场;然后根据自然伽马场和自然电位场与岩相之间较好的对应关系,对岩相进行三维建模。应用此方法建立了准噶尔盆地中部莫西庄某井区主要储集层三工河组二段二砂层组(J1s22)的岩相模型,结果表明,该方法有效地弥补了井间信息不足的缺陷,所建模型能够很好地揭示该区内砂体分布和油水分布。图5表1参8
The multi-step modeling technique is used in the description of sandstone and shale reservoir with seismic and well-logging data in the area of large well distance and less well drilled.The natural gamma and spontaneous potential are simulated in the way of collocated co-Kriging simulation.In this process the well-logging data is constrained by seismic information according to the relationships between impedance with natural gamma and spontaneous potential.Then a lithofacies modeling is built on the relationships between GR and SP with lithofacies.The method was used to establish the lithofacies modeling of J_1s_2~2 in Moxizhuang,middle Junggar Basin.The modeling can predict the sandstone's distribution and explain the complicated distribution of oil and water.
