摘要： 复杂构造和深层石炭系已成为在准噶尔盆地寻找有利油气区带的重要领域之一,但这些地区资料往往信噪比低,成像质量差。叠前共反射面元叠加技术利用常规叠加速度可以获得比常规叠加剖面更高的信噪比,特别对复杂构造连续性的提高有一定的效果,它与叠前偏移技术结合处理是提高资料品质的有效方法之一。

Abstract: With the development of geophysical prospecting technologies, the complex structure and deep Carboniferous become one of favorable areas for petroleum exploration in Junggar basin. However, the imaging quality is often difficult to satisfy the requirement for petroleum exploration due to low signal-to-noise ratio of the seismic profiles in these areas caused from complicated surface and deep burial conditions. Increasing the imaging precision is an urgent task. Using the common reflection surface stack technology (CRS) can obtain higher signal-to-noise ratio than conventional stack profile, particularly, has a certain effect in improving complex structure continuity. In addition, integrated with prestack migration technology in seismic profile processing, CRS is one of effective methods for increasing the information quality.
