摘要
火成岩是一种不同于正常沉积岩的特殊岩性体,在济阳坳陷的成盆期,伴随着构造运动,发生了多期岩浆活动,在下第三系地层中发育了形态、成因各异的火成岩体。根据火成岩的地震反射外形特征,总结归纳了不同类型火成岩体的地震相特征,运用一系列的物探新技术、新方法,对火成岩进行了地震识别及综合解释,为火成岩的勘探开发奠定了坚实的基础。
Igneous rock is a special lithesome that is different from normal sedimentary rock. In basin forming period of Jiyang depression, tectonic movement was accompanied by multiphase magmatic activities, and igneous rocks of various occurrence and genesis had developed in lower Tertiary formation. According to seismic reflection features of igneous rocks, characteristics of seismic facies of different types of igneous rocks have been summarized. Seismic identification of igneous rocks and integrated interpretation has been carried out by using a series of new geophysical techniques, thus establishing a solid basis for exploration and development in igneous rocks.
