But the improving effect and benefit of downholeoperation have not formed yet.
但系统地提高井下作业效果与效益的管理思路尚未形成。

Formation burst pressure is one of the key parameters for the thermal production of heavy oil, drilling engineering and downholeoperation.
地层破裂压力是钻井工程、井下作业及稠油油藏热力开采的重要参数。

Therefore, the calculation on the amount of deformation is not only an important work in force analysis of packer string, but also an important factor to ensure the downholeoperation.
