在石油生产过程中 ,泡沫有许多用途 ,它可作为钻井液 ,用来使油藏增产或用于二次采油。与过去相比 ,现在可以应用泡沫从快速衰竭的油藏中开采更多的油气 ,并且是重钻设计井眼中的有效手段。随着欠平衡钻井技术的发展 ,泡沫已成为低比重钻井液选择的介质。泡沫是有效的低比重钻井液 ,携岩能力极强 ,即便在环空流速低时泡沫仍有效 ,这就排除了漏失的可能性 ,实际上排除了钻柱差压卡钻的可能。泡沫最重要的好处是作业者可边钻边开采。
In the oil production process, the foam has many uses, it can be used as a drilling fluid, used to increase the reservoir or for secondary recovery. In contrast to the past, foam can now be applied to extract more hydrocarbons from rapidly depleted reservoirs and is an effective means of re-drilling the wellbore. With the development of underbalanced drilling technology, foam has become the medium of choice for low specific gravity drilling fluids. Foam is an effective low specific gravity drilling fluid and has very high rock carrying capacity. The foam is effective even at low annular velocities, which eliminates the possibility of loss and virtually eliminates the possibility of drill string differential caliper drilling. The most important benefit of foam is that workers can drill while drilling.
