川南河包场区块茅口组缝洞系统定量描述
|
摘要
在河包场构造钻遇下二叠统茅口组的16口井均位于逆断层上,有11口井获工业气流,其中5口井测试产气20×10~4m~3/d以上。该区茅口组茅四茅二段储层为裂缝和溶洞组成的储集体,为了定量描述缝洞系统的空间分布和发育规模,对下二叠统逆断层和茅口组茅四—茅二段储层顶、底进行了精细对比追踪,对茅四—茅二段进行了高分辨率的逆断层约束速度反演,并结合叠前、叠后地震属性选取敏感属性进行缝洞系统的定量检测,最后利用三维可视化技术融合高分辨率逆断层速度反演结果和高精度相干属性数据体进行缝洞系统三维雕刻,定量刻画了该区茅口组有利的缝洞系统空间分布情况。
In Hebaochang Structure,the 16 wells which drilled the Lower Permian Maokou Formation are located on the thrust faults.Among these wells,11 wells obtained industrial gas flow and 5 wells achieved more than 20×10~4m~3/d testing production.The 4~(th) to 2~(nd) member of Maokou Formation of Hebaochang Structure is the reservoirs composed by fractures and caves.In order to quantitatively characterize the spatial distribution and scale of the fracture-cave system,we carried out fine correlation and tracing on the thrust fault of lower Permian and the top and bottom of 4~(th) to 2~(nd) member of Maokou Formation.High-resolution thrust-fault constrained velocity inversion was carried out on the interval,combined with prestack and post-stack seismic attributes;the sensitive attributes were selected to quantitatively detect the fracture-cave system.Finally, 3-D visualization technique,together with high-resolution thrustfault constrained velocity inversion and high-precision coherent cubes,were applied for the 3-D sculpture of fracture-cave system, and the favorable spatial distribution of fracture-cave system is quantitatively characterized.
