摘要/Abstract

摘要：

稠油油藏化学驱因原油黏度较高和储层非均质性严重,使得驱替液往往通过优势渗流通道而出现早期突破甚至无效循环,最终导致采收率较低,需要研究在低黏度下能够高效建立阻力能力而实现较好流度控制且能显著调整非均质性的驱油剂及体系。在相近黏度下,以部分水解聚丙烯酰胺（HPAM）为对比,较为系统地研究了缔合聚合物（HAWSP）的阻力系数、均质流度控制能力和非均质性调整能力。相近黏度下,渗透率范围在（300~2 000）×10^-3 μm²,缔合聚合物的阻力系数约为300×10^-3 μm²下HPAM所建立的4倍,且缔合聚合物对110.7 mPa·s原油有明显稳定的驱替前缘和更高的提高采收率值;均质条件下,缔合聚合物与HPAM有类似的产聚表现和存聚率,而在非均质下,前者的存聚率（63.4 %）显著高于后者（5.2 %）;4倍渗透率级差下,缔合聚合物在高低渗层中的分流表现出明显的交替移动且能够使后续水驱在较长时间内保持较高的低渗层分流率;5倍渗透率级差下,缔合聚合物能驱替簇状模型中高低渗区域的大部分残余油,且在外围大流道中可观察到“拉丝”和“油路桥接”现象。结果表明：缔合聚合物有显著的流度控制和非均质调整能力,这也从海上油田缔合聚合物驱现场的应用得到证实,因此,缔合聚合物在稠油油藏的开发中具有较大应用潜力。

Abstract:

Due to high oil viscosity and severe heterogeneity, heavy oil reservoirs generally lead to the poorer oil recovery due to the early breakthrough and ineffective circulation of displacing fluids through the prevailing flowing channels. It is necessary to develop the oil-displacing agents or systems which can efficiently generate resistance at low viscosity to achieve better mobility control and significant heterogeneity control. Compared with HPAM, the abilities of the resistance factor generation, mobility control under homogenous condition and heterogeneity control under heterogenous condition of associative polymer（HAWSP） have been studied at a similar viscosity. The results show that, when at the similar viscosity, the resistance factor generated by HAWSP in the permeability range of （300 ~ 2 000）×10^-3 μm² is nearly four times of that generated by HPAM with the permeability of 300×10^-3 μm², and HAWSP has a significantly stable displacement front and obtains a higher EOR for oil with the viscosity of 110.7 mPa·s. When under the homogeneous conditions, HAWSP has similar behavior with HPAM in the aspects of polymer production and retention ratio. On the contrary, when under the heterogenous conditions, the former has a significantly higher retention ratio（63.4 %） than the latter（5.2 %）. When at a permeability contrast of 4 times, the fractional flow of HAWSP in the high and low permeability layers exhibits an obvious alternating movement, and HAWSP can enable subsequent water to maintain a high fractional flow in low permeability layer for a long time. When at a permeability contrast of 5 times, HAWSP can displace the most of the cluster-like residual oil trapped in the model, and the phenomenon of "drawing" and "oil bridging" can be also observed in the outer large flow channels. The results indicate that associative polymer has significant abilities to control mobility and adjust heterogeneity, which can also be demonstrated by associative polymer flooding field application in offshore oilfield. In a word, associative polymer has greater application potential in the development of heavy oil reservoirs.

Key words: heavy oil, associative polymer, HPAM, mobility control, heterogeneity adjustment
