稠油冷采技术在胜利油田应用的可行性探讨

注蒸汽开采是提高稠油油藏采收率的有效方法，但存在着采油成本高以及在高轮次吞吐后期含水上升、产量递减加剧等问题。针对以上问题，列举了各种稠油冷采方法及其适用条件，其中包括出砂冷采、低频脉冲采油、井筒化学降粘、化学吞吐、Vapex方法、碱驱、注CO2方法、注烟道气方法等。分析了胜利油田未动用稠油油藏的开发难度，对稠油冷采技术在胜利油田应用的可行性进行了探讨．提出了建议。

Feasibility study of CHOP in Shengli Oilfield

Steam injection is an effective way of enhancing heavy oil recovery factor, but it can cause problems such as high production cost and high water cut after several steam injection cycles. Aiming at these problems, this paper gives most of the cold heavy oil production technologies and their adaptive situations, including CHOPS (cold heavy oil production with sand), LF pulse oil production, wellbore chemical viscosity-reduction, chemical huff-and-puff, Vapex, alkali flooding, CO_2 injection and flue gas injection. The difficulties of producing undeveloped heavy oil reservoirs in Shengli Oilfield are analyzed. This paper also discusses the feasibility of CHOP in Shengli Oilfield and gives some suggestions.
