准噶尔盆地陆梁油田陆9井区呼图壁河组(K1h62-K1h72)油藏为构造幅度低、油水关系复杂、非均质强的边水油藏。应用数值模拟方法,紧密结合油藏精细描述和油藏工程研究结果,研究了该油藏合理的技术开发政策界限,最终确定了该油藏应立足于注水开发,合理采油速度为2.9%,合理注采比是0.8,合理压力水平应保持在9.0MPa左右;油藏仍应采用反九点井网方式进行配注等开采技术政策界限。数值模拟研究结果对油田实际开发有很好的指导作用。
The Hutubihe Formation (K1h62-K1h72) reservoir in Lu 9 well of Luliang oilfield in Junggar Basin is a marginal reservoir with low tectonic amplitude and complicated oil-water relationship. Applying the numerical simulation method, in combination with the detailed description of the reservoir and the reservoir engineering research results, the reasonable technical development policy boundary of the reservoir was studied. Finally, the reservoir should be determined based on the water injection development. The reasonable oil recovery rate was 2.9% The injection-production ratio is 0.8 and the reasonable pressure level should be maintained at about 9.0MPa. The reservoir should still adopt anti-nine-dot pattern to allocate technical policies such as pens. Numerical simulation results of the actual development of the oil field has a good guiding role.
