油气遥感预测效果及勘探应用
|
摘要
油气遥感技术的理论机制和预测效果，应当被勘探人员充分认识和接受。苏北盆地金湖凹陷1988年以油气色调异常处理解释技术预测的码头注、纪庄、银集西等十几个有利异常区，现已为8年来的勘探成果证实确为不同类型的商业油气田。松辽盆地1992年完成的钻井与油气水色调异常吻合率研究表明，该区油气井的色调异常吻合率达83％。事实证明油气遥感预测技术既可用于勘探选区，也可用于布开。在开展二维地震测量的详查探区，若结合遥感预测布并，可以减少三维地震工作量，提高钻井成功率。但是必须以严格的线一环一色油气圈闭影像识别模式的处理解释技术为保证，才能获得良好的应用效果。
Oil and gas remote sensing forecast has not been recognized as a practicable method of oil and gas exploration, because of theinsufficient awareness of the effectiveness and the mechanism of this method This article introduces the mechanism for oiland gas remote sensing forecast and a brief "lineament-ring structure-hue anomaly" model of remote sensing image as well astwo examples. There are nearly 10 hue anomaly areas which have been proven to be the commercial oil and gas fields duringthe 8-year practice of selecting the exploratory area in Jinhu depression. The agreement rate that are interpreted for remotesensing hue anomaly amounted to 83% 'for oil and gas in the western slope of Songliao basin, which suggests that this methodmay also be used in deciding the exploratory drilling place, and the joint use of 2D seismic prospecting and the oil and gasremote sensing forecast technology may greatly reduce the amound of 3D seismic work and raise percentage of hits in thedetail shooting area. Besides, some skills used in the technology and conditions related to the method are also discussed in thisarticle.
