摘要: 径向井压裂技术与蒸汽吞吐热采技术的联合是一种有效适用于低渗透稠油油藏且兼具经济性的开发技术,目前在国内还处于现场实验阶段,缺少理论研究。通过径向井压裂物理模拟实验研究压裂裂缝形态,并在实验结果的基础上进行径向井压裂辅助蒸汽吞吐产能数值模拟研究。结果表明:径向井对压裂裂缝的扩展具有一定的引导作用,多径向井条件下会产生多裂缝形态,有效提高了泄油面积;径向井压裂辅助蒸汽吞吐产能是常规压裂辅助蒸汽吞吐产能的2.65倍(3年累计产油量),证明了该技术在低渗透稠油油藏的适应性,并在此研究基础上以产能为标准明确了该联合技术中的最优热采参数。研究结论为现场径向井压裂辅助蒸汽吞吐技术开采低渗透稠油油藏提供了理论依据,对该技术的发展完善和应用具有指导意义。

Abstract: The technology of radial well fracturing combined with steam soak is suitable for the development of heavy oil reservoir with low permeability,but it is lack of mechanism research so far. The fracture morphology of radial well fracturing was studied by 3 D simulating experiment,and the thermal deliverability of radial well was researched by simulation. The results show that multi-cracks morphology is performed under the multi radial wells which could increases the drainage area,and the radial well can guide the fracture of hydraulic fracturing well. The steam soak stimulation assisted by radial well fracturing is very effective for the development of heavy oil reservoir with low permeability,and the productivity gets the best effect when the number of the radial wells is 4. The thermal deliverability in 3 years of radial well fracturing is 2.65 times larger than that of regular fracturing. The applicability of the combined technology was proved and the parameters of steam soak were optimized. The conclusion is significant and important for the development of heavy oil reservoir.
