关于 cement system,主要是用水泥层隔离作用的
The most important function of oil & gas well primary cementing is to isolate the various zones within the wellbore. In others words, the cement must prevent fluids or gases in one particular zone from mingling with those of another. A properly designed and placed cement slurry accomplishes this by creating the necessary seal between the casing and the formation. The cement must prevent migration or fluid channeling throughout the cement.
关于 mud system和mudpump 主要是通过泥浆泵的循环,把钻井的碎块啊,泥浆啊,等等带出井眼,并通过一些其他设备分开开,泥浆要循环使用的
The drilling mud system performs several important functions to oil & gas well drilling. These include the removal of drill cuttings, the prevention the entry and migration of formation fluids by maintaining proper hydrostatic pressures, as well as wellbore and tool lubricity. |
