aLast chapter simply introduces estimation of gas at atmospheric pressure in formation. This chapter describes the process of stable foam drilling, how to determine the minimum gas volume required, the purpose is to design the drilling rig and select more effective, need air and gas compressors ...
The solution provides facility to view the progressive stages of a well if the relevant data for each stage is available. For example, it is possible to view and analyze the changes in a well’s completion status after each rig or rigless event against changes in production figues after each...
It is convenient and effective to design and analyze the transmission system of drilling rig by speed diagram,so the relationship of transmission pairs could be distinctly reflected. 利用转速图设计和分析钻机的传动系统,是一种比较简便和有效的辅助设计方法,能清晰而有条理地反映传动系统各传动副的关系。
