    摘要:

    库车坳陷东部吐格尔明背斜经历多期构造变形与断裂活动,地震资料品质差,油气水分布复杂。构造解析合理性直接影响对研究区构造运动学过程、动力学机制以及油气成藏规律的认识。本文以野外观测数据、钻井和地震数据为基础,对库车坳陷东部吐格尔明背斜进行构造解释,运用平衡剖面恢复原理,对研究区构造演化进行了恢复,在此基础上对构造控藏作用进行了探讨并指出了有利勘探区。结果表明,研究区主要发育吐孜洛克断层和吐格尔明断层,其中吐孜洛克断层主要从上新统库车组沉积期开始活动,活动强度大、控制了翼前巨厚的生长地层和现今吐格尔明大背斜的形成;吐格尔明断层从侏罗纪末开始陆续活动至今,控制古隆起的形成;研究区在平面上由南向北可依次划分为深部凹陷区、南翼斜坡区、中部背斜区以及北翼斜坡区四个区带。构造演化对不同区带的埋藏演化过程、储层物性特征和盖层保存条件具有明显的控制作用,其侏罗系有利勘探方向主要有:背斜斜坡背景上的局部构造高,背斜南翼和北翼斜坡带低部位的构造—岩性圈闭以及断层下盘的深部构造—岩性圈闭。

    Abstract:

    The Tugerming anticline in the eastern Kuqa depression has experienced multi-stage tectonic deformation and fault activity, with poor seismic data quality and complicated distribution of oil, gas and water. The structural analytical rationality directly affects the understanding of the structural kinematic process, dynamic mechanism and hydrocarbon accumulation law in the study area. Based on the field investigations, boreholes and seismic data, this paper explains the structure of the Tugerming anticline in the eastern Kuqa depression, and restores the tectonic evolution of the study area by using the principle of balanced profile restoration. On this basis, the tectonic controlling effect of reservoir is discussed and the favorable exploration areas are pointed out. The results show that the Tuziluoke fault and Tugerming fault are mainly developed in the study area. The Tuziluoke fault mainly started to be active in the deposition period of Kuqa Formation, and the activity intensity is large, which controls the huge thickness of growth strata in forelimb and the formation of the Tugerming anticline. The Tugerming fault has been active since the end of Jurassic and controlled the formation of paleo-uplift. In plane, the study area can be divided into four zones from south to north: deep sag area, south slope area, middle anticline area and north slope area. Tectonic evolution obviously controls the burial evolution process, reservoir physical properties and preservation conditions of cap rocks in different areas, the Jurassic favorable exploration direction mainly include: local structural high position of anticlinal slope, structure-lithologic trap in the lower part of the slope zone of anticline′s south and north limb, and deep structure-lithologic trap in the footwall of fault.
