摘　　要：罗家地区的深层稠油具有埋藏深、原油黏度高、储层物性差等地质特点,常规热力试油往往吸汽能力低、注汽压力高、注汽质量差,致使试油效果不理想。针对深层超稠油的试油难点,近几年来在该地区加强了超稠油技术措施的配套,并在两口重点井分别开展了低伤害压裂、超临界锅炉注汽及化学冷采等配套工艺先导试验,应用后试油获得较好的效果,对类似区块超稠油勘探试油及开发具有一定的借鉴意义。For deep geological features of heavy oil at Luojia area being a deep buried depth,high crude oil viscosity,poor geological characteristics,the conventional thermal oil test is often low vapor absorption capacity,high steam injection pressure,poor quality of steam injection,which results in the effect of oil test being not ideal. According to test difficulties of deep super heavy oil,mating of technical measures to heavy oil are strengthen in recent years at this area,and pilot tests of low damage fracturing,supercritical boiler steam injection and chemical cold mining and other supporting technology are carried out respectively on two key wells. The oil tests after the application obtain good results,which has certain reference significance for prospecting and development to similar block.
