Description

The pipe guiding piece that is used for snubbing unit
Technical field
The present invention relates to be used for the pipe guiding piece that uses at snubbing unit (snubbing units), said snubbing unit is used for the pipe snubbing to oil well and gas well and will manage from oil well and gas well and trip out by force.
Background technology
Snubbing unit is used for pipe is fed into missile silo and from missile silo, trips out.Common snubbing unit comprises the stationary slip (stationary snubbing slips) of snubbing service or the traveling slip (traveling snubbing slips) of clamp and snubbing service, so as along with the traveling slip of snubbing service towards and away from the stationary slip motion of snubbing service alternately clamping and releasing tube.
Nowadays usually adopt two interlockings and telescopic pipe between the traveling slip of the stationary slip of snubbing service and snubbing service at the conventional tube guiding piece that uses on the snubbing unit.These pipe guiding pieces intrinsic problem comprise that the space of manage guidance system and weight and they are to height that snubbing unit increased.In addition, lost the only about half of effective travel of snubbing unit, therefore if compare with the situation that can implement complete not kill-job stroke, not kill-job remove operation become poor efficiency many.
In the big well of pressure (live well) or before the Guan Zaiguan that the big well of pressure trips out by force bends, only can be supported limited amount compressive force by snubbing.Confirmed compressive load allowed to bear before pipe is bending in the length of the pipe of the exposure between the position that the position and the pipe of the traveling slip grip tube of snubbing service is exposed to the well head outside.
When under not having the situation of managing guiding device, overcoming well and compress into capable snubbing service, be used to prevent that crooked reasonable security factor from can expose to such an extent that be longer than by obtaining with the relevant pipe that fricative power supported of sealing station that keeps well to press through not making tube portion.Other factor, the pipe speed that is inserted in the well or from well, removes for example, be common precompose already calculate whole, need these precomposes already to calculate so that confirm the maximum permission length that pipe can be exposed in advance when the situation that possible bending do not occur is finished drilling longitudinal tubule (L tubule).In case accomplished these calculating, the snubbing service operator uses short stroke that pipe is moved in the well or from well and shifts out, and never allow to use exceed amount of calculation can not be supported exposure.
The hydraulic pressure snubbing unit is divided into two kinds of configurations usually, promptly self-contained free-standing configuration and drilling rig assist type snubbing unit.Self-contained free-standing configuration can suitably be worked for the big well of pressure, and the overall height of equipment is not so important in this case, because be not used in the spatial constraints of handling the pipe wait to be inserted into the big well of pressure or to remove from the big well of pressure usually.
Yet; For drilling rig assist type snubbing unit; Overall height is important, because snubbing unit must be worked snubbing unit and drilling rig joint operation in the height restriction of the crown of a part that forms drilling rig.Got rid of selection in many cases at the top of snubbing unit with from the distance between the inside, working region at the top of drilling rig derrick, because equipment will not allow to have the enough spaces that are used for pending length of tube to the excessive height that snubbing unit increases with pipe guiding device.Therefore, the operator takes on the high-pressure well of danger, to carry out aforesaid short stroke operation.
Support column is to prevent that crooked pipe guiding piece from being known.These guiding pieces position between the traveling slip of the stationary slip of snubbing service and snubbing service usually guide the pipe that carries out snubbing service through loose guided rings.Guided rings must have enough diameters, passes with the instrument jointing (tool joint connection) that allows to have than the bigger external diameter of pipe itself.
