[求助] 钻井液、石油开采方面，英译汉

1、Wellbore stability, including low fracture gradients

2、Typically, wells are drilled riserless through these zones, using seawater and bentonite sweeps. Once a shallow hazard is detected there are two realistic alternatives: 1) spot a kill fluid and run casing or 2) drill ahead with a weighted fluid.

3、Typical riser volumes may range from 1,000 to 3,000 bbl。

4、if kick detection is of vital importance then an aqueous fluid is best as gas is not soluble in water and so gas kicks are more easily detected.
