摘要

摘要: 渤海湾盆地是我国潜山油气资源勘探的重点地区之一，为了打开该区太古宇潜山勘探新局面，对辽东湾地区太古宇潜山成储规律及主控因素进行了研究。基于薄片、测井、地震等钻井资料，分析了辽西凸起中北段太古宇潜山岩石学特征、岩石展布特征、储层特征、构造演化和裂缝特征。研究表明，辽东湾地区辽西凸起太古宇潜山由片麻岩类、变质花岗岩类和碎裂岩类等组成，并以片麻岩为主；现今构造呈南高北低特征，北部地层保存相对完好，南部地层上部具剥蚀迹象，岩浆岩比例自北向南逐渐增高。该区太古宇变质岩以裂缝型储层为主，岩石中暗色矿物含量与岩石脆性呈反比关系；构造变形导致裂缝发育，太古宇潜山发育三组构造裂缝，即燕山早期受到NE向强剪切和SN向强挤压的应力方向发育NNE向剪裂缝和SN向张裂缝，喜马拉雅早期受到NW向强伸展和NE向弱剪切的应力方向发育NE向剪裂缝和北东向张裂缝，喜马拉雅晚期受到NE向强剪切和NW向弱伸展的应力方向发育EW向张裂缝及NE向和NW向共轭剪裂缝，区域构造差异活动程度控制了裂缝的有效性；燕山运动是变质岩储层主要造缝期，喜马拉雅期裂缝以方解石充填、半充填为主，后期经溶蚀可构成有效裂缝。

Abstract: The Bohai Bay Basin is one of the key areas for the exploration of buried hill oil and gas resources in China. In order to create a new prospect for the exploration of the Archaean buried hills in this area, the reservoir-forming laws and main controlling factors of the Archaean buried hill reservoir in the Liaodong Bay area were studied. Based on drilling data such as stratum, logging, and seismic data, this paper classified the lithology and distribution patterns of Archean buried hills in the Liaodong Bay area, and analyzed the dominant reservoir space types and controlling factors. The results show that the Archean buried hills in the Liaodong Bay area are composed of schist, metamorphic granite and cataclastic rocks, with schist being the predominant lithology. The current structure is high in the south and low in the north. The strata are relatively intact in the north, while the upper part of the strata in the south shows evidence of denudation. The proportion of igneous rocks increases gradually from north to south. The metamorphic rocks are dominated by fracture reservoirs. The content of mafic minerals is inversely correlated with the brittleness of rocks. Tectonic deformation led to fracture development. Three sets of structural fractures were developed in the Archean buried hills of the Bohai Bay Basin, i.e., NNE shear fractures and SN tensile fractures were developed in the stress directions of NE strong shear and SN strong compression in the early Yanshanian period, NE shear fractures and NE tensile fractures were developed in the stress directions of NW strong extension and NE weak shear in the early Himalayan period, and EW tensile fractures and NE and NW conjugate shear fractures were developed in the stress directions of NE strong shear and NW weak extension in the late Himalayan period. The degree of regional tectonic activity controlled the effectiveness of the fractures. The Yanshanian movement was the main stage of fracture formation in metamorphic rock reservoirs. During the Himalayan period, fractures were mainly filled and semi-filled with calcite, and effective fractures could be formed through dissolution in the later stage.
