海上某稠油油田热采井注汽温度对储层保护的影响

摘要

The effects of steam inj ection temperature on reservoir protection of offshore thickene d oil ther-mal recovery well were studied on three aspects of reservoir permeability damage rate,suspended solid content of output liquid,compatibility of output liquid and oilfield formation water.The results showed that the appro-priate temperature was less than 270 ℃ during steam injection process in thickened oil.%主要从储层渗透率的损害率、产出液的悬浮物含量、产出液与油田地层水的配伍性等方面综合研究了注汽温度对海上某稠油油田热采井储层保护的影响。结果表明：该稠油油田在热采注汽过程中的注汽温度不宜超过270℃。
