克拉玛依油田原油中原生生物的特性及应用

根据克拉玛依油田稀油区块本源微生物驱油的实验室研究和矿场实验的实际情况以及对稠油区块本源微生物驱油的实验室可行性研究,总结出克拉玛依油田稀油和稠油油藏原生生物的特性和应用价值。相对于稠油区块来说,稀油区块本源微生物含量较低,活性较差。通过对本源微生物进行筛选、培养、重新注入的方法提高原油采收率效果显著,而稠油区块本源微生物含量高,活性好,用直接注入培养基激活本源微生物的方法提高原油采收率效果理想,并同时实现了对高黏度、高钙稠油的乳化降黏和脱钙作用,降黏率达到50%以上,脱钙率达到90%以上。

The Protist of Crude Oils in Karamay Oilfield: Features and Application

Based on the lab experiments and field tests of in-situ original microbes drive in light oil blocks and the lab feasibility studies of such a drive in heavy oil blocks in Karamay oilfield,the features and applied values of the protist in light and heavy oil reservoirs in this oilfield are presented.It is suggested that in light oil blocks the content of in-situ original microbes is relatively low,with poor activity,for this reason,the screening,culturing and re-injection of the microbes can notably enhance ...
