摘　　要：针对春光油田中深薄层超稠油开发技术瓶颈问题进行了分析,研究应用了以降黏、氮气助排为主体的热化学辅助蒸汽吞吐技术,分析了原油黏度与含水率变化规律,优选了降黏剂及工艺参数。现场应用后油井日产油量、周期产油量和油汽比显著提高,油井产状得到明显改善。The problems of technologic bottleneck of middle-deep thin reservoir of super-heavy oil development in Chunguang Oilfield were Analyzed,the technologies in viscosity reduction and nitrogen cleanup were researched and applied.The change rules of oil viscosity and water content were analyzed,a viscosity reducer and process parameters were optimized.After field application,daily oil production、cyclic oil production and oil-gas ratio are obviously raised and the well occurrence is obviously improved.
