摘要

摘要: 上覆地层介质为横向均质的情况下,火成岩侵入作用所形成的特殊构造物理模拟实验结果表明,岩浆侵入过程向正上方呈蛇曲状盘旋上升,剖面上呈左右摆动上升的形态;顶部构造平面形态呈圆形或近圆形拱起,拱起边界呈封闭型断层。岩浆侵入脆性地层具有应力积聚和释放的交替过程,呈现脉动跳跃现象,岩浆通道形状不规则;岩浆侵入塑性地层的应力变化过程平稳连续,岩浆通道向四周扩张明显,通道直径加大,顶部各地层构造形态具有继承性特点。实验模拟结果可以合理解释渤海湾盆地济阳坳陷SH24构造的形成发育机制;勘探结果表明岩浆侵入产生的这类派生构造对油气成藏十分有利。该实验成果填补了国内火成岩侵入构造物理模拟实验的空白,并取得了相关的实验参数,为今后类似的实验提供借鉴。

Abstract: In the instance of overlying strata being transverse homogeneous medium,the results of physical simulation experiment for the special structure formed by invasion of igneous rock indicate that the process of magma invasion spirals up snake-shapedly in the upper direction,and ascends oscillatingly in the profile.Top structural configuration is rounded or near round arch,and its boundaries are blocking faults.The process of magma invasion to brittle strata is alternative with stress accumulation and release,in which microseism leap and irregular channel of magma are shown.In the course of magma invasion to plastic strata,the stress varies smoothly and consecutively,the channels of magma obviously spread around,the diameter of the channels increasies,and the structural configuration of the top strata has the characteristics of inheritance.The result of simulation test can logically interpret the developing mechanism of SH24 structure in Jiyang Depression.Exploration results indicate that this kind of derived structures in the process of magma invasion is very benefit to reservoir formation.The results of this experiment fill up the blank of domestic physical simulation for the structure formed by invasion of igneous rock and have acquired the related experiment parameters,which provides experience and reference for the future analogous experiments.
