摘要
顺北地区以走滑断裂带控制的缝洞型储层为勘探对象,经过多期岩溶改造且埋藏深、结构复杂,地震反射特征认识不清,勘探难度大。首先针对勘探难题设计多组断控缝洞型储层模型进行正演模拟,分别得到了断控缝洞型储层在表层和内幕的不同反射特征认识。然后在断控缝洞型储层地震反射特征认识的基础上,开展了储集体多种预测技术的探讨,通过多种方法技术的组合运用,刻画了断控储集体的空间形态和内部结构,取得了良好效果。
This paper takes the fault controlling fractured-vuggy reservoir controlled by strike-slip fault zone in Shunbei area,as the object of exploration.Due to its multi-stage karst transformation,its deep burial,complex structure and unclear seismic reflection,the exploration tends difficult.In view of the exploration difficulties,multiple sets of fault-controlled fracture-cavity reservoir models are designed to carry out forward simulation and the different reflection characteristics of fault-controlled fracture-cavity reservoir on the surface and inside are obtained respectively.Based on the seismic reflection characteristics of fault-controlled fracture-cavern reservoir,this paper probes into various prediction techniques of the reservoir collection.The spatial form and internal structure of fault-controlled reservoir are described through the combination of various methods and techniques,and good results are obtained.
