摘要
从克拉玛依油田采油二厂八区P2W1分离得到两类以固体石蜡为碳源生长的清防蜡菌种。实验证明这些细菌能够耐高温、产生表面活性剂和有机酸、对原油和石蜡具有强降解能力。在室内复配成混合菌种DPM4-2,在60℃下培养7 d后对黑蜡和固蜡的降解率分别为43.1%和54.9%,对原油的降粘率为27.3%-43.6%。综合分析混合菌种适用于该区块油井的清防蜡作业。
Two kinds of microorganism are got from the second factory eight area P2W1 of Kelamayi Oilfield, which are living with wax as carbon source. These bacteria can resist high temperature, produce biosurfactant and organic acid, and can degrade crude oil and paraffin. The mixed bacterium DPM4-2, after cultivated at 60℃ over 7 days, can lead to degrading of the paraffin deposition and paraffin by 43. 1% and 54. 9% , respectively. The oil viscosity decreases by 27. 3% - 43.6%. It＇s concluded that this mixed bacterium is suitable for the paraffin control of the second factory eight area P2W1 of Kelamayi Oilfield.
