吐哈盆地鄯善油田影响注水因素分析

Analyses on the affective factors of downflow wells in Shanshan oilflied of ThHa Basin

利用吐哈盆地鄯善油田区域物性资料和吸水测试资料统计分析,发现该油田目前存在的注水效率低,无法到达预期配注目的问题及现象,从影响储层注水的内因和外因入手,综合考虑各种因素,重点从注水水质因素、注入水与地层配伍性及敏感性等方面进行分析研究,提出了合理化建议。

By analyzing physical data and intake profile data of Shanshan oil field in the Tuha Basin,we find the low efficiency of the water injection can not reach the anticipated purpose.So we analyze the inner and outer reasons of preventing water injection.We consider all kinds of factors,especially study the water characters of injection,matching and sensitivity between the water injection and formation.Finally,we offer a conclusion and some advices.
