叠前时间偏移在吐哈盆地温西南地区的应用
|
摘要
根据吐哈盆地温西南地区三维地震资料的特点,在该地区应用了叠前时间偏移成像处理技术,提高了地震剖面的品质。波组特征好,构造清楚,浅、中、深层反射成像好;偏移速度场合理,断点、断面清晰;构造成像清楚,效果良好。为定向井的井位设计提供了可靠的地震资料。通过对该资料的精确解释,先后在该地区提出钻探井位四口,其中三口获得工业油气流。
According to the characteristics of 3D seismic data in southwest area of Wen Jisang of Tuha basin, the quality of seismic section has been promoted by the application of prestack time migration imaging in this area. With good characteristics of wave group and clear structure, the reflection imaging in shallow and middle and deep zone is good; the migration velocity field is reasonable, the break point and cross-section are clear; structure imaging is clear with good effect. It provides reliable seismic data for directional well position design. With precise interpretation for data, four exploratory well's locations have been proposed in this area, three of which have industrial hydrocarbon flow.
