【摘要】：大港探区孔店油田馆陶组为辫状河沉积。辫状河沉积,近物源,储层较厚,以"砂包泥"为特征,储层复杂多变,一般高孔高渗。由于这些特点,在以往的研究中通常以构造控藏思路为主。然而随着开发的推进及钻井的增多,多区存在"高水低油"的油藏关系矛盾。成藏规律复杂,储层的展布及变化不清。所以非常有必要展开储层的精细预测,从而明确井间储层分布规律,为岩性油气藏的研究奠定基础。本文首先利用地层切片技术宏观分析研究区的沉积背景;然后在模型正演的指导下,应用90°相位化技术、分频技术划分沉积相带;最后应用流体活动性属性预测研究区储层含油气性。
[Abstract]:Guantao formation in Kongdian Oilfield of Dagang exploration area is braided river sedimentary, near material source, thick reservoir, characterized by "sand and mud", complex reservoir, high porosity and high permeability. In the past studies, the main idea of reservoir control is structure control. However, with the development of development and the increase of drilling, there is a contradiction of reservoir relationship between "high water and low oil" in many areas, and the law of reservoir formation is complex. The distribution and variation of the reservoir is not clear. So it is very necessary to develop the fine prediction of the reservoir so as to make clear the distribution law of the reservoir between the wells. In this paper, we firstly use stratigraphic slicing technology to macroscopically analyze the sedimentary background of the study area, then, under the guidance of model forward modeling, apply 90 掳phase technique and divide frequency technique to divide sedimentary facies zone. Finally, the oil and gas properties of the reservoir in the study area are predicted by the fluid activity attribute.
