摘要/Abstract

摘要： 渤海油田A区块底水稠油油藏斜对双水平井SAGD生产规律较复杂，剩余油饱和度和含水率均较高。通过物理模拟实验方法对正对、斜对双水平井SAGD开发过程中温度场变化特征和生产规律进行了分析，并结合数值模拟方法，探讨了注采压差对SAGD生产效果的影响，明确了斜对双水平井SAGD的合理注采压差范围。研究结果表明：①正对双水平井SAGD蒸汽腔向模型两侧扩展，蒸汽腔两侧的斜面泄油能力均衡，而斜对双水平井SAGD蒸汽腔扩展速度及斜面泄油能力都不均衡，蒸汽腔波及面积更小，采出程度更低；双水平井SAGD的生产过程可分为产油速度上升阶段、稳定生产阶段和下降阶段，其中稳定生产阶段蒸汽腔处于横向扩展阶段，以重力泄油为主。②渤海油田A区块的SAGD生产井存在10 m避水距离，数值模拟结果显示，当底水能量小于10倍，底水对水平井SAGD的生产效果基本无影响；双水平井SAGD稳定生产阶段，随着注采压差的增大，注汽量和产液量逐渐升高，产油量先增加后逐渐降低，累积油汽比先升高后降低，sub-cool值和汽液界面高度逐渐降低；生产井未发生汽窜时，正对双水平井产油量大于斜对双水平井；正对、斜对双水平井SAGD合理注采压差分别为20~30 kPa和30~40 kPa。

Abstract: SAGD production law of inclined dual horizontal well in the bottom water heavy oil reservoir of block A in Bohai Oilfield is complex, with high remaining oil saturation and high water cut.Through the physical simulation experiment, the characteristics of temperature field change and production laws of the forward and in clined horizontal wells during the SAGD development process were analyzed. Combined with the numerical simulation method, the influence of injection-production pressure difference on SAGD production efficiency is discussed, and the reasonable injection-production pressure difference range of horizontal well SAGD is clarified. The results show that : (1) SAGD steam chamber of the forward dual horizontal well extends to both sides of the model, and the oil drainage capacity of the inclined plane on both sides of the steam chamber is balanced.However, the expansion speed of the SAGD steam chamber and the oil drainage capacity of the inclined plane ofthe inclined dual horizontal well are unbalanced, resulting in a smaller steam chamber coverage area and lower recovery degree. The production process of dual horizontal well SAGD can be divided into three stages: oil production rate rising stage, stable production stage and falling stage. In the stable production stage, the steam chamber is in the lateral expansion stage, which is dominated by gravity drainage.(2) The SAGD production well in block A of Bohai Oilfield has a water avoidance distance of 10 m. Numerical simulation results show that: when the bottom water energy is less than 10 times and the bottom water has no effect on the production efficiency of horizontal well SAGD. In the stable production stage of dual horizontal well SAGD, with the increase of injection-production pressure difference, the steam injection and liquid production gradually increase, the oil production first increases and then gradually decreases, the cumulative oil-steam ratio first increases and then decreases, and both the sub-cool value and the height of steam-liquid interface decrease gradually. When there is no steam channeling in the production well, the oil production of the forward horizontal well is greater than that of the inclined horizontal well. The reasonable injection-production pressure difference of SAGD in forward and inclined horizontal wells is 20-30 kPa and 30-40 kPa, respectively.
