The time when the cement slurry's column pressure reduces to the water column pressure before or after initial set is directly related to whether or not formation fluids flow out during wait-on-time.
水泥浆的有效浆柱压力是在初凝前还是在初凝后降低至水柱压力,直接关系到能不能在固井候凝过程中压稳地层流体、实现压稳防窜候凝。
What happens is this: the water column gradually heats, but high pressure keeps the deeper parts from boiling.
这一切是这样发生的:水柱被逐渐加热,但是压力使深处的水不能沸腾。
To provide accurate reading of head pressure , the line should connect at the base of the water column.
为了提供精确的水头压力参数,管线应该连接到水柱的底部。
