In the following soak (shut-in) phase, the well is shut in for days to allow the heat to dissipate in the reservoir and the heavyoil to heat up and become less viscous.
在接着的浸泡(关井)阶段,关井数天,使热量在储层中消散并使重油加热和降粘。

Highly viscous crude oil is commonly transported with mixing technique (heavy crude and light crude) in order to reduce viscosity.
高粘原油降粘通常采用稠油与轻质原油混合输送的方式。

Heavyoil is very viscous, range of size distribution of sand is wide, which are technical problems of desanding process.
