摘要
针对东濮凹陷复杂断块油气田的特点 ,在马厂地区三维老资料连片处理中 ,应用了三维叠前时间偏移处理技术 ,提高了地震资料的成像精度。在断块小而多的破碎带 ,使用该技术效果尤其明显 ,剖面上断裂系统结构清楚 ,断点可靠 ,和井资料吻合程度高 。
According to the characteristics of complex fault block oil/gas fields in Dongpu depression, 3 D prestack time migration technique was adopted in data processing for piecing together various 3 D data sets acquired from Machang area. Results show that 3 D prestack time migration technique can effectively improve the image precision of seismic data, especially in fractured zones with abundant minor faults. The resulting sections are characterized by clearer fractured system, reliable breakpoints, and matching well with well data, which provide solid foundations for well location design of directional wells.
