| 摘 要： | 稠油出砂冷采技术是油层大量出砂形成蚯蚓油和稳定泡沫油而形成，该技术的使用可获得较高的原油产量。河南油田通过攻关，在稠油出砂冷采领域取得良好的应用效果。形成了普通稠油出砂冷采开采技术，成功地将特薄互层和中深层普通稠油难采储量投入开发，第一口出砂冷采先导试验井日产油量是常规试油产量的8倍以上、是蒸汽吞吐产量的4倍以上，开采成本比蒸汽吞叶降低47％。同时，还成功地将出砂冷采技术应用于普通稠油低周期蒸汽吞吐井中，日产油提高1－3倍，进一步拓宽了该技术应用领域。

| Abstract: | The cold production technology of heavy oil is based on both earthworm shapedchannels which occur after a great lot of sand is produced and steady foamy oil, by which the oil production can be remarkably enhanced. This technology has found satisfactory application in Henan Oilfield and also successfully used in middle depth, very thin heavy oil reservoirs. The oil rate of first pilot well was8 times that of the common wells, 4 times that of the steam soaking wells, whilethe production cost was 47% less that of the steam soaking wells. This technology was also successfully applied to low cycle steam soaking wells in heavy oil reservoir, which improved the oil rate by 1-3 times. |
