近年来,苏联油气井钻探中越来越多地采用泡沫钻进方法。过去对泡沫的研究,多数是在大气条件下进行的。钻探用泡沫的工作条件,与其他行业用泡沫的条件,全然不同,其特点是在高于大气压条件下起泡,而随后要经受附加压缩,泡沫承受的压力和温 In recent years, more and more foam drilling methods have been used in oil and gas well drilling in the Soviet Union. In the past, most studies on bubbles were conducted under atmospheric conditions. The working conditions of drilling foams are fundamentally different from those of other industries. They are characterized by foaming at above atmospheric pressure, followed by additional compression, the pressure at which the foam is exposed, and the temperature
