摘要
试验室经分离得到了 5株能以蜡为唯一碳源生长的微生物菌种 ,在室内对其生长、降粘、降凝、清蜡等性能进行评价后 ,应用于克拉玛依油田进行清防蜡现场实验。结果表明 ,混合菌的清防蜡效果显著 ,11口井在 4个月试验期共增产原油 5 14 8.6t,节约热洗 36次 ,创直接经济效益 36 0 .4× 10 4元。成功地解决了该区块油井结蜡严重、热洗周期短、生产管理难度大。
Five kinds of microorganism are got from lab, which are some kinds of microorganism living only depend on wax. After evaluated their ability, such as increment, decreasing the viscosity and solidifying point of crude oil and clearing wax, applied it in Karamay oil field to clear wax. The result of clearing and preventing wax via mixed microorganism is remarkable. 5148.6 tons of crude oil has increased. 36 times of hot washing has saved. 3.604 million yuan direct economic benefit has been created. Some producing problem of this oil field has been solved, such as much wax solidified, short duration between hot washing, difficult manage during producing, and high production cost too.
