作者指出,要继续维持石油产量的大幅度增长,必须多打井,打深井。苏联和美国已能钻5000-8000米深井,正计划钻1000O-15000米超深井。钻超深井将遇到许多困难,首先是高压高温引起的一系列问题。泥浆比重很难确定,细微的比重变化将使液柱压力大大改 The author points out that to continue to maintain a substantial increase in oil production, we must make more wells and make deeper progress. The Soviet Union and the United States have been able to drill 5000-8000 m deep wells and are planning to drill 1000 O-15000 m ultra-deep wells. Drilling ultra-deep wells will encounter many difficulties, the first is a series of problems caused by high pressure and temperature. Mud gravity is difficult to determine, subtle changes in the proportion of liquid column pressure will greatly change
