| 摘 要： | 塔里木盆地奥陶系碳酸盐岩中＂非串珠状＂缝洞型储层经钻探已取得较好效果,但目前针对其储层类型及成因的研究较少。根据碳酸盐岩缝洞储集体发育程度及受风化壳和裂缝的影响程度,将在地震剖面上表现为＂非串珠状＂反射的缝洞型储层划分为3种类型,分别是内幕缝洞体规模较小的缝洞型储层、距风化壳较近的缝洞型储层以及裂缝型储层,进行正演模拟,并与实钻资料结合,详细探讨各自的地震反射特征和地质成因。

| Abstract: | Drilling of none-string beads fracture-cavity reservoir has got a good effect in the Ordovician carbonate of Tarim basin,but the research about type and cause of the reservoir is not yet enough till now.Based on developing degree of cave-cleft bodies and influence of weathering crust and fracture,none-string beads fracture-cavity reservoirs in seismic section reflection are divided into three types,including reservoir with small scale inner cave-cleft bodies,reservoir closer to weathering crust and fracture... |
