摘要
塔河油田所辖的6区、10区北及12区原油属高黏度、高含硫、高含蜡的超重质稠油。尤其是12区油藏,原油平均密度高达1.025 9 g/cm3,黏度高达300 000 mPa.S。上述区块油井在试油初期存在极大的凝管风险。为此,提出了一套全新的防凝管工艺技术。该工艺技术经室内试验和现场评价,取得较好的应用效果。
The crude oil in the regions of 6, North10 and 12 is super heavy oil which is high sulfur content, high viscosity and high wax content in Tahe Oilfield. Especially in the region of 12, the average density of crude oil reached 1. 025 9 g/cm3 and the viscosity reached 300 000 mPa. s. Oil wells which are in the above regions have risk of coagulating tubing in initial stage of oil testing. Therefore, a set of new technology of anti-coagulating tubing is presented. The results of laboratory test and field evaluation show that this technology obtains a favorable effect.
