(1) moving time of drilling platform t = SV =1.728×106m2/s = 8.64×105s = 240h;

(2) The specific gravity of oil with a volume of 1m3 is g = mg = ρ VG = 0.8×103kg/m3×10n/kg = 8×103n.

The work done to overcome petroleum gravity is w = GH = 8×103n×1500m =1.2×107j.

A:

(1) The moving time of the drilling platform is 240 hours; ;

(2) The work done to overcome the gravity of oil is1.2×107 j. 。
