摘要: 稠油出砂冷采技术是油层大量出砂形成蚯蚓洞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,开采成本比蒸汽吞吐降低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 produc-tion 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.

Key words: heavy oil production, sand production, steam soaking
