综合利用地球物理资料解释叠合盆地深层火山岩
|
摘要
叠合盆地深层火山岩是中国油气勘探的重要领域。在深层火山岩的研究中,地球物理资料解释具有其独特的作用。利用高精度重磁勘探和电法资料,了解盆地深部结构和深大断裂,初步圈定深层火山岩体的展布,缩小和锁定深层火山岩地震勘探的有利靶区;以地震相分析、地震属性解释、构造制图、地震反演、综合评价为主要技术手段,对深层火山岩进行从定性到定量的识别和预测,落实和优选深层火山岩有利勘探目标。通过几年来的解释与实践,取得了较好的勘探效果。在松辽盆地和准噶尔盆地共发现54个火山岩体,提供24口井位,有13口井获得不同数量的天然气。
The volcanic rock in superposed basin is important field in China oil/gas exploration. The interpretation of geophysical data has unique role on study of deep volcanic rock: using the data of high-precision gravity and magnetic exploration and electric exploration to know deep structure and large fault of basin, preliminarily trap the distribution of deep volcanic rock and shrink and lock benefit target zone of seismic prospecting for deep volcanic rock; taking seismic facies analysis, seismic attributes interpretation, structural mapping, seismic inversion and integrative evaluation as major technical means to carry out from qualitative to quantitative identification and prediction of deep volcanic rock, determine and optimize the favorable prospecting targets of deep volcanic rock. The better exploration effect has been achieved by several years' interpretation and practice. 54 volcanic rock bodies have been found totally in Songliao Basin and Jungar Basin, where 24 well sites have been provided, in which the natural gas to a different degree has been acquired in 13 wells.
