摘要/Abstract

摘要： 最近在克拉玛依百口泉油田发现了一组北北西向走滑断裂带, 十余条走滑断层将北东向的克乌断层截为十数段, 并依次错开。走滑断层在三维地震水平切片上有清晰显示, 主要表现为: 各波组同相轴的终端呈线状定向延伸;波组同相轴图像有牵引现象; 同属一套同相轴波组图形被明显错开; 同相轴的波形突然变化; 一套波组突然同向弯曲等。走滑断层在地震剖面上的显示不如水平切片明显, 但也有一定特征: 中生界波组突然中断消失, 与石炭系基底杂乱反射对接在一起; 波组有中断现象, 一系列中断点呈高角度向深部延伸; 波组呈现波状变动或表现为反射突然模糊等。走滑断层为张扭性质, 是北东向逆断层的配套滞后产物。百口泉油田油气最为富集的区块恰与走滑断层发育带基本吻合, 故百口泉走滑断裂带对油气富集成藏以建设性作用为主。

Abstract: A set of NNW strike-slip fault belts has been found in Baikouquan oilfield, Karamay area. The Karamay-Wuerhe great fault of NE trend was truncated into ten more pieces by this fault. Its 3D seismic horizontal slices clearly display that each wave group appears such event ends as directional linear extension, the event image is dragged, the same event waveforms are apparently dislocated and suddenly changed, and a suit of waves is abruptly bended in a same direction. Its seismic profile shows that the Mesozoic waves disappear suddenly and joint with messy reflection of Carboniferous basement, the waves appear interrupted points with high-angle extending down deep, the waves vary in undulance or the reflections become obscuring suddenly, etc. It is concluded that this strike-slip fault is in tensoshear property and should be lagging products associated with reverse fault of NE trend. The oil-enriched blocks accord generally with this developed fault belt, indicating its contribution is mostly constructive to hydrocarbon accumulation in Baikouquan oilfield.

Key words: strike-slip fault, 3D, horizontal slice, tenso-shear property, hydrocarbon accumulation, constructiveness, Baikouquan oilfield
