冷41断块深层超稠油油藏采油工艺技术研究

冷41断块属深层超稠油砂砾岩油藏，开发过程存在着注汽压力高、井筒热损失大、汽窜等问题，为此开展了专项研究。通过积极试验、推广采油配套工艺技术。使该油藏得以成功开发。特别是通过研制应用新型节能降耗、降低生产成本等配套工艺技术。实现了该油藏的高效开发。其成功的做法对于国内其它相似油藏的开发具有一定的借鉴作用。

Study on oil recovery technique for deep super- heavy oil reservoir in fault block Leng 41

Fault block Leng 41 is a deep super - heavy oil glutenite reservoir. Problems like high steam injection pressure, heat loss in wellbore and steam channeling have appeared in developing process, and special study for these problems has been conducted. By doing experiments and spreading matching techniques of oil recovery, this reservoir has been developed successfully. Particularly, by developing and applying new techniques of energy saving and cost reduction, this reservoir has been developed with high efficiency. This success is a reference to the development of other similar reservoirs.
