济阳坳陷中生代负反转构造发育特征
|
摘要
以高精度三维地震资料和钻井资料为基础,综合运用构造解析、平衡剖面恢复、断层活动速率和反转强度系数等方法,对济阳坳陷中生代负反转构造发育特征进行分析。结果表明:济阳坳陷中生代负反转构造以断层反转为主要表现形式,走向以NW向为主,剖面上表现为断面延伸至新生界或隐伏于新生界之下2种类型,卷入地层可划分为挤压剥蚀层序(古生界)、压-张过渡层序(侏罗系)和拉张裂陷层序(下白垩统);负反转断层的主反转期为晚三叠世至早白垩世,断层活动强度相应经历了较大负值、较小负值和正值的变化;主反转期内反转强度系数为1～7,整体具有自北东向南西降低的趋势。
Based on high-precision seismic data and drilling data,the development characteristics of Mesozoic negative inversion structures in Jiyang depression were studied by using the methods of structural analysis,balanced cross section,fault activity rate and inversion intensity coefficient. The results show that the main manifestation of the Mesozoic negative inversion structures in Jiyang depression is fault inversion and the fault strike is mainly NW trending. The negative inversion structures in the vertical section extended to Cenozoic or buried in Cenozoic. Involved formation is subdivided into extrusion and thrusting sequence (Paleozoic),extrusion-extension sequence (Jurassic) and extension chasmic sequence (Lower Cretaceous). The main inversion phase is from Late Triassic to Early Cretaceous and the activity intensity of the negative inversion fault correspondingly shows larger negative values,smaller negative values and positive values. The inversion intensity coefficient in main inversion phase is from 1 to 7,and overall inversion intensity decreases from northeast to southwest.
