深层稠油油藏射孔参数优化研究

OPTIMIZATION OF PERFORATION PARAMETERS FOR DEEP HEAVY OIL RESERVOIR

吐玉克区块是吐玉克油田即将投入规模开发的深层稠油油田,油藏埋藏深,原油粘度高,通过孔眼流动特征比较复杂。考虑到稠油井选择套管射孔完井,针对稠油油藏特征,对影响稠油井产能因素进行了敏感性分析,并对稠油井射孔参数进行优化,确保发挥稠油井最大产能。

Block Tuyuke in Tuyuke oilfield, a deep heavy oil reservoir is about to be put into full scale production in the near future, which has great burial depth, high oil viscosity and complex flow characteristics in passing channel. Providing the wells in this region are completed by well-cased perforating, the sensitivity of factors affecting well productivity is analyzed, and perforation parameters are optimized to maximize productivity.
