摘　　要：LKQ超深层稠油油藏由于埋藏深,常规稠油开发方式无法实现有效开发,为世界难题。吐哈油田公司对此进行了有益的探索,利用天然气作为介质注入油藏进行天然气吞吐采油,取得初步效果。2005—2006年进行了二轮次矿场单井试验,结果证明注天然气吞吐采油可以有效降低地层原油粘度,提高地层稠油流动性,油井单井产量提高了2-5倍,周期平均单井产量达到8 t/d,使难采储量达到经济开发的要求,为油田整体开发动用奠定了基础,对超深层稠油开发具有借鉴意义。The ultra deep burial depth of heavy oil reservoir in LKQ oilfield has brought about a problem to the world that is hard to tackle with conventional development mode. Tuba Oilfield Company obtained primary success on developing ultra deep beavv oil reservoirs with cyclic nature gas injection. Results of the 2 rounds of field tests carried out in 2005 and 2006 showed that nature gas injection could effectively reduce viscosity and enhance fluidity of heavy oil in stratum and through tile development mode, the yield of wells raised to 2-5 times more than the former one, meanwhile, the average yield of well was up to 8 tons per day. This method settles the foundation for overall development of ultra deep heavy oil reservoir.
