中文摘要: |
伊拉克中南部M油田为强非均质性碳酸盐岩油藏,其主力油藏X层系存在高渗透小层,渗透率极差大,井与井之间注水连通性、对应性及非均质性急需得到确认。为解决问题选取注采井组,在注水井中注入化学示踪剂并对井组中生产井的产出结果进行监测,运用井间示踪剂技术并建立相关数模模型加以分析和解释,得出井间体积波及系数,平面波及系数等参数,为现场的工艺技术设施提供了依据。更好的了解了此类油藏油水井间动态连通性,弄清注入流体在各层的推进方向、推进速度,及纵向上的非均质性等情况。为类似油田开发提供了较可靠的借鉴经验。 |
英文摘要: |
Strong heterogeneity is normally appear in the carbonate reservoirs in the Middle East. The M oilfield is the one which is more prominent located in the southern part of Iraq. There is a high permeability layer exists in the X formation of the main reservoir, which leads to large difference in permeability. Water injection connectivity and heterogeneity need to be confirmed. In order to solve the problem, the tracer technology is used to track injection water, and then the relevant numerical model is used to analyze and interpretation. The research results and parameters provide a reliable scientific basis for a better understanding of the dynamic connectivity between producers and injectors in such reservoirs, to understand the direction of propulsion, advanced speed, and longitudinal heterogeneity of the injection. It provides a more reliable experience for similar oilfield development. |
