【摘要】：随着油田勘探开发形势的发展,越来越多的岩性油气藏被发现并成为油田增储上产的主阵地之一,扇三角洲砂砾岩体油藏在其中占有重要位置。而隐蔽性砂砾岩油气藏,是储层预测和描述中比较困难的一种类型。因此,研究扇三角洲砂砾岩体储层描述的地球物理技术对于指导此类油藏的勘探和开发具有重要的现实意义。寻找隐蔽性油气藏,非常重要的手段之一,是找出储层岩性及物性变化与沉积特征的关系和变化规律。而地震反射资料,通过地震相或地震响应特征的变化,可以提供沉积特征在平面和空间的变化。针对玛湖凹陷扇三角洲砂砾岩体储层,通过测井和三维地震技术的综合应用,将地质信息和地球物理技术有机地结合在一起,我们进行了这类储层地震预测工作。本文首先利用地震相分析确定扇三角洲宏观分布规律,然后针对目标扇体利用地震属性等地球物理响应特征对砂砾岩体内部结构特征及物性特征进行精细刻画。本次主要研究了准噶尔盆地西北缘玛湖凹陷区三叠统扇体沉积特征在地球物理资料上的响应。充分利用三维地震资科,通过井震精细标定、等时切片、地震相等综合手段,精细刻画了砂体的空闻分布特征。本次研究中的扇三角洲储层预测工作主要是围绕井位部署,通过一些地震资料储层预测新技术新方法的应用,开展目的层段沉积-岩性特征横向变化、优质储层区的空间分布和变化特征为该地区的勘探部署提供依据和支撑。
[Abstract]:With the development of oilfield exploration and development, more and more lithologic reservoirs have been discovered and become one of the main positions for increasing reserves and production in the oilfield. Fan delta sandy conglomerate reservoirs occupy an important position in the reservoirs. Geophysical techniques for describing conglomerate reservoirs are of great practical significance in guiding exploration and development of such reservoirs. One of the most important means of searching for subtle reservoirs is to find out the relationship between lithological and physical changes of reservoirs and their sedimentary characteristics, and the law of variation. In view of the fan-delta sandy conglomerate reservoir in Mahu Sag, the geological information and geophysical technology are combined organically through the comprehensive application of logging and three-dimensional seismic technology, and the seismic prediction of this kind of reservoir is carried out. The macro-distribution law of fan delta is analyzed and determined, and then the internal structure and physical properties of glutenite are described in detail according to the geophysical response characteristics of target fan, such as seismic attributes. In this study, the fan delta reservoir prediction work is mainly centered on the well location and the application of some new techniques and methods for reservoir prediction with seismic data. Lateral variation of accumulation-lithology characteristics, spatial distribution and variation characteristics of high-quality reservoir areas provide the basis and support for exploration deployment in this area.
