降凝降黏剂在原油开采集输中的应用

Application of crude oil pour point and viscosity reducer in gathering and transportation of crude oil exploitation

降凝降黏剂已成为钻高难度的高温深井、大斜度定向井、水平井和各种复杂地层的重要手段,并且还可广泛地用作解卡液、射孔完井液、修井液和取心液等。由于稠油的黏度以及凝点低,防止在开采过程中出现困难,降凝降黏剂的应用需要进行一定的关注,解决其发展困难。

pour point and viscosity reducing agent has become an important means to drill high-temperature and deep wells, high angle directional wells, horizontal wells and various complex formations with high difficulty, and it can also be widely used as releasing fluid, perforating completion fluid, workover fluid and coring fluid. Due to the low viscosity and pour point of heavy oil, it is necessary to pay attention to the application of viscosity reducer to solve the development difficulties.
