断层相关褶皱在塔里木盆地玛东地区的应用
|
摘要
玛东褶皱-冲断带是世界上保存最好的早古生代褶皱冲断带之一,也是塔里木油气勘探的重点区域之一。褶皱—冲断带浅部构造由于遭受强烈剥蚀,为玛东褶皱—冲断带的构造样式和变形机制研究带来巨大的挑战。断层相关褶皱理论定量化建立了断层形态和褶皱形态几何学和运动学的关系,是一种有效的利用断层形态来推测褶皱形态的方法,为恢复玛东地区被剥蚀区域的构造形态提供了可能。文中详细介绍了断层转折褶皱和断层传播褶皱的几何学和运动学特征,并将其应用于玛东地区的典型构造中,建立2种玛东地区构造变形模式。最后结合工业地震剖面和钻井资料,认为玛东地区的主要构造样式是断层转折褶皱,并分析了构造样式对油气圈闭的影响。
Madong fold and thrust belt is one of the best preserved fold and thrust belt forming in Early Paleozoic, and also the hot-point of the oil and gas exploration in Tarim Basin. The erosion in the anticline of the thrust cause the low resolution of the seismic data, which make the structural model and deformation mechanism of Madong fold and thrust belt confusing. The fault related folding theory established the quantitive relationship between fold geometry, fault geometry and fault slip, which is an efficient method for building the fold geometry using known fault shape. Madong fold and thrust belt is a well natural example for the application of the fault related folding, with well constrained fault geometry and eroded anticline. We introduce the geometric and kinematic models of fault-bend fold and fault propagation fold, and apply these two models to the typical structure in Madong fold and thrust belt. Using the geometric relationship of fault-related fold, we build two probable models of Madong fold and thrust belts for fault-bend fold and fault propagation fold, respectively. Considering the coincidence of the models with seismic data and drilling data, the fault-bend fold is the most suitable model for the geometric and kinematic model of Madong fold and thrust belt, and the influence of structural model on hydrocarbon traps is also discussed.
