Comprehensive geophysical study on the distribution characteristics of deep strata in Lujiapu area, Songliao Basin

摘要:
对于盆地中的浅层勘探，地震探测技术表现出高分辨率和强纵向分层能力的特点. 然而，当涉及到凹陷的深层区域时，由于火山岩等的屏蔽作用，地震信号变弱，成像质量也会下降，这使得推断深部地层发育特征变得极为困难. 大地电磁测深技术不受火山岩层的影响，并对深部的泥岩等低阻层信息敏感，因此在深部信息提取上与地震技术形成互补，能够获取关于基底格架和电性标志层的起伏信息. 重、磁异常主要受到体积效应的影响，并且是被动源，没有屏蔽，只要有明显的密度差异或界面存在，重力或磁力异常就会在地表反映出来，这为密度、岩性、侵入体分布等研究提供了有力的手段. 针对松辽盆地南部陆家堡及周边地区义县组深部地层的复杂地质背景，本文利用重、磁、电、震等多种地球物理方法的优点，对该地区的深部地层、岩性、构造等分布特征进行综合研究，可为后续的深层系油气勘探提供参考.
Abstract:For shallow exploration in basins, seismic detection technology exhibits advantages of high resolution and strong vertical stratification capability. However, when dealing with deep sag regions, due to the shielding effect of formations like volcanic rocks, which makes seismic signals weaken and imaging quality deteriorated, the interpretation for the development characteristics of deep strata becomes extremely difficult. Magnetotelluric(MT) sounding is unaffected by volcanic formations and is sensitive to low-resistivity information such as mudstones in deep subsurface. Therefore, it complements seismic technology in terms of deep information, enabling acquisition of details about basement framework and undulation of electrical marker beds. Gravity and magnetic anomalies, as passive sources, are mainly influenced by volume effect, without shielding. As long as significant density contrasts or interfaces exist, gravity or magnetic anomalies will be reflected at the surface. These methods provide a powerful mean for the intergraded study of density, lithology, distribution of intrusive bodies, etc. Given the complex geological background of deep Yixian Formation strata in Lujiapu area and its surroundings in southern Songliao Basin, this study leverages the advantages of multiple geophysical methods including gravity, magnetic, electric, and seismic(GMES) techniques to comprehensively explores the distribution characteristics of deep strata, lithology, and structures in the area, which provides references for subsequent oil-gas prospecting of deep reservoirs.
