利用油藏数值模拟方法对底水油藏应用水平井及直井开采技术效果进行了对比研究,分析了采油速度、布井方式及垂直渗透率与水平渗透率比值(Kv/Kh)对开发效果的影响。结果表明,水平井开发底水油藏的效果远远优于直井。水平井在平面上的布局,在低采油速度下对开采效果影响较大,而在高采油速度下则影响不明显。地层的Kv/Kh值对水平井开采效果影响明显。
The reservoir numerical simulation method is used to compare the technical effects of horizontal well and vertical well mining with bottom water reservoir. The effects of oil production rate, well pattern and ratio of vertical to horizontal permeability (Kv / Kh) are analyzed. influences. The results show that horizontal wells are far superior to vertical wells in developing bottom water reservoirs. The layout of horizontal wells in the plane has a great influence on the mining effect at low oil recovery rates, but not obvious at high oil recovery rates. Stratum Kv / Kh value has obvious effect on horizontal well mining.
