塔里木盆地巴楚地区大型膝褶带的发现及油气勘探意义
|
摘要
利用野外地表露头、重新处理的地震反射剖面及钻井资料,详细解析并重新认识了巴楚隆起的构造变形特征,提出巴楚地区以往解释的主导构造样式"两断夹一隆"中的具高角度特征的"断层"大多数并不是断裂,而是大型膝褶带,"两断夹一隆"中的"两断"实际是一对共轭膝褶带。同时提出,这种具高角度特征的膝褶带及其褶皱构造是克拉通盆地内在挤压背景下的一种重要变形样式,膏盐层与不连续地层界面的广泛发育以及区域顺层挤压缩短变形是该区形成大型膝褶带的重要地质因素。结合膝褶带的形成机制,分析了它与大型断裂带的区别,并建立了识别地下大型膝褶带的几何形态、地震反射和应力指示等标志。在巴楚隆起形成演化历史研究基础上,探讨了巴楚地区古生界膝褶变形在改善储层和形成圈闭方面的油气地质意义,分析了其油气勘探前景,并指出了寻找大型膝褶型背斜油气藏的有利区带。
Outcrop observation,reprocessed seismic reflection profiles and drilling data were integrated to describe the characteristics of structural deformation of Bachu uplift. The previously interpreted structural style was "one uplift between two fault zones". However,the previously interpreted fault zones with deep angle were not faults but a pair of conjugate kink-band structural zones. It is believed that the large kink-band structural zones and the fold structures in the area are the dominant styles of structural deformations in the abdomen of the cratonic basin under compression. The widely developed gypsum-salt bed and discontinuous bed boundary and regional along-bedding compressional deformation are the vital geological factors controlling the formation of the large kink-band structural zones. Marks like geometry,seismic reflection and stress were presented for identification of large underground kink-band structural zones based on their formation mechanism and differences with large fault zones. On the basis of research on history of Bachu uplift,we discussed the implications of the Paleozoic kink deformation to reservoir improving and traps forming,analyzed their exploration prospect and outlined the favorable zones for discovering large anticlinal reservoirs of kind fold type.
