【摘要】 为了降低地震断层解释中的不确定性,以松辽盆地杏北开发区三维地震资料为靶区,以断层"转换位移/离距(D/S)"为基础,建立了断层平面分段生长定量判别标准,其中,侧列叠覆、开始破坏和完全破坏3个阶段的临界D/S分别为0.27和1。研究结果表明,1杏北开发区278+273断层是由278断层和273断层侧列叠覆组成,同时验证了断层分段生长定量判别标准的可靠性;2断圈类型由单断下盘翘倾型断圈校正为侧列叠覆断层孤立型断圈,同时断圈范围也明显变小;3断层封闭性评价由整体评价校正为278断层和273断层分别独立评价。因此,断层组合校正对油气田勘探开发方案的精确部署具有重要的指导意义。更多还原

【Abstract】 In order to reduce the uncertainty in the seismic fault interpretation,taking Xingbei development area of Songliao Basin as example and based on the fault transfer displacement / sepatation( D / S),quantitative discrimination criterion of fault segmentation growth on the plane is eatablished. The critical D / S value of the three periods( arrangement overlap,initial break,total break) is 0. 27 and 1. The research shows: 1 Fault 278 + 273 in Xingbei development area is consist of fault 278 and fault 273 which are arrangement overlap and the quantitative discrimination criteria of fault segmentation growth and is reliable. 2 The type of fault trap is corrected from single fault trap whose footwall tilting to isolated fault trap which is arrangement overlap. At the same time,the range of fault trap becomes significantly smaller. 3 The assessment of fault sealing is corrected from general evaluation to independent evaluation on fault 278 and 273 respectively. Therefore,fault combination correction has great significance on precise deployment of exploration and development in oilfield.更多还原
