| 摘 要： | 由于避开了地表低降速带和风化层的影响,井间地震能够采集到高频地震信号,经过资料处理可以得到较高分辨率的速度和上行反射波成像剖面。2004～2005年,胜利油田在垦71 区块实施了8对井间地震资料采集。针对原始资料特点,研究了以层析成像、管波衰减、VSP-CDP技术和有限角度叠加成像等关键处理技术,较好地完成了该区块的井间地震资料处理。初步分析解释表明,井间地震可以识别低序级断层、小幅度构造和薄储层。 |

| Abstract: | As cross-well seismic exploration can avoid the impact of the low-velocity layer and weathering layer, it can acquire relatively high frequency seismic signal. After processing, fairly high resolution velocity and reflection imaging can be obtained. During 2004-2005, eight cross-well seismic profiles were processed in Ken 71 Block, Shengli Oil Field. In accordance with the characteristics of raw data, the authors studied tomography, tube wave attenuation, VSP-CDP and finite angle stack, and completed the cross-well seismic data processing. The analysis and interpretation of the final results show that cross-well seismic exploration can recognize small faults, small structures and thin reservoirs between two wells. |
| Keywords: | cross-well seismic exploration computer tomography tube wave attenuation VSP-CDP finite angle stack |
