摘　　要：利用水平井多元热流体吞吐开采技术开采稠油油藏,可有效增加注入流体波及范围,提高稠油油藏动用程度,从而大幅提高采收率。受油藏、工艺、增产机理等因素综合影响,各因素对开发效果的影响程度是不明确的。为找出影响水平井多元热流体吞吐的主控因素,进一步提高开发效果,以我国渤海M稠油油藏为研究对象。通过对油藏、工艺参数及开发效果进行统计,将影响水平井多元热流体吞吐的各因素看成灰色系统。利用灰色关联分析方法计算得到各因素与吞吐效果的关联度,并对各因素影响程度进行评价,得出影响水平井多元热流体吞吐效果的主控因素。结合油藏数值模拟,对主控因素进行了适应性分析及优化,为海上稠油油藏利用水平井进行多元热流体吞吐开采提供了技术参考依据。The application of horizontal wells for the multi-component thermal fluid stimulation in the heavy oil reservoir can en- large the injected fluid swept volume and improve the producing degree, so that to enhance the oil recovery. Affected by the reser- voir condition, the production technology, the recovery mechanism and so on, the influence degree of each factor is ambiguous. In order to find out the main controlling factors for the further improvement of the development efficiency, heavy oil reservoir M in Bo- hai bay is selected as the study object. Based on the statistics of influencing factors, all the influencing factors were considered as a grey system. The main controlling factors were obtained through the influencing degree evaluation, and were computed through grey relation analysis for each factor. Combined with the reservoir numeric simulation, the adaptable analysis and optimization were done for main influencing factors. The results of this study provide the necessary technical reference for the multi-component ther- mal fluid stimulation by horizontal wells in the offshore heavy oil reservoirs.
