稠油出砂冷采技术简介出砂冷采技术是加拿大等国近年来兴起的一项稠油开采新技术。目前,该技术在加拿大的应用规模已超过6000口井该技术属一次采油范畴,不需要向油层中注入蒸汽,而可获得比常规开采以至注蒸汽开采高得多的产量,是降低稠油开采成本、提高资源利用率的一项非常重要的开采技术国外经验表明,采用该技术后,单井日产油量一般大于5_1,采收率一般可达5%～ Introduction of heavy oil sand production technology Cold sand production technology is emerging in Canada and other countries in recent years a new heavy oil recovery technology. At present, the technology has more than 6,000 wells in Canada. This technology is a primary oil field. It does not need to inject steam into reservoirs, and can achieve much higher yields than conventional or even steam injection, which is to reduce heavy oil production Cost, improve resource utilization is a very important mining technology experience shows that foreign countries, using this technology, single well daily oil production is generally greater than 5_1, recovery generally up to 5% ~
