Three calculation methods have been used to study waxy oil temperature drop after shutdown for both buried pipeline and overhead pipeline.
本文用三种计算方法研究了埋地和架空管线中多含蜡原油管道停输后的温降,并与现场实测结果作了初步比较。
Thick, old, waxy oil can only be bad.
粘稠的,旧的,蜡状的机油只能使情况更糟。
In the light of the difficulty in artificial lifting of waxy oil well, high pour-point oil well and viscous oil well, a new tubing heating system is developed.
针对含蜡油井、高凝油井、稠油油井生产过程中的举升难题,研制了一种新型油管加热采油装置。
PPD makes the critical radius and the potential barrier of nucleation of wax crystal increase, and makes the separation of wax from waxy oil difficult.
降凝剂提高了蜡晶析出的临界半径,增大了成核位垒,使蜡晶析出困难。
An experimental instrument for researching pipe flow is used to study thixotropy of waxy oil flowing in pipeline.
