n: the bit cant be lowed in to the bottom during tripping in because the bottom is piled for caving or the cuttings in the fluid dipping

n: the sticking that because the property of drill fluid is not good, causing layer is became slack because of too much filter loss,or the argillutite swelled because of the hole section which angle of bedding are too large stripping into the well.

n: The operation of forced tripping in at the case of high pressure in the hole.

n: The operation of forced tripping in at the case of high pressure in the hole.

n: 1. a device that mechanically or hydraulically forces pipe or tools into the well against pressure. 2. a device within some hooks that acts as a shock absorber in eliminating the bouncing action of pipe as it is picked up.

n: A suit of equipment be controled by hydraulic pressure,which can tripping in at definite pressure.

n: either a stand-alone device or a rig-assist device that is used to force pipe into the well when the well is shut in on a kick. When the pipes weight is not sufficient to overcome the upward force of well pressure, a snubbing unit must be used. Compare stripping in.

n: 1. the process of lowering the drill stem into the wellbore when the well is shut in on a kick and when the weight of the drill stem is sufficient to overcome the force of well pressure. 2. the process of putting tubing into a well under pressure.

v: shutting in and stripping in when well blowout .

v: The stripping operation achieved by reverse switch of preventer when there has high pressure in the hole.

n: The soft,easy drill and cavy surface layer that need tripping in surface casing to cement.

running pipe into the well.
