摘要
稠油出砂冷采是使油层大量出砂形成蚯蚓洞和形成稳定泡沫油而获得较高的原油产量。通过稠油出砂冷采领域的攻关研究 ,河南油田形成了普通稠油出砂冷采开采技术 ,成功地将稠油难采储量投入开发。第一口稠油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%。已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。图 2参 4(胡常忠摘 )
In a cold production process, the well gets a high oil production with withdrawal of large amount of sand and formation of foamy oil. Henan oil field has reached abundant achievements, in cold production technology application and controlling the cold production strategies for heavy oil, and has practiced commercially in very thin bedded and middle depth heavy oil reservoirs. The first pilot well's oil rate was 8 times that of conventional test, and 4 times that of steam soaking. At the same time, the producing cost is less than that of steam soaking by 47%. Additionally, HPEB succeeded in low cycle steam soaking wells, in which, daily oil rate is 1 3 times higher than that of steam soaking wells. Thus, the range of using cold production technology was further extended.
