Description
Technical field:
The utility model relates to a kind of petroleum drilling well workover technology field, particularly the telescopic wellhead slurry umbrella device of one.
Background technology:
Need in drilling and repairing well construction, in blowout preventer upper end, well head pipe guide is installed, the function of this device allows drilling fluid set up circulation between pit shaft and ground circulating tank, and be used for when making a trip connecting in pouring pipe alignment pit shaft and pour into mud, subsidiary slurry basket is used for reclaiming the raffinate that well head flows down.Existing conduction pipe device is generally by the top class in a kindergarten of drilling team of each basic unit onsite application electrogas welding processing and fabricating, and material is surface pipe.Existing conduction pipe device exists following not enough: 1, in wellbore construction process because end flange height is different, needed for link and change, surface pipe sinks after waiting the solidifying apical grafting of falling open union, blowout preventer body height is different, link and calculate or all duct height demand is changed to some extent under measuring many situations such as there is error, therefore need the new conduit of on-the-spot processing and fabricating; 2, sidetracking overhaul well construction generally all welds together with production string due to flange at the bottom of former well head, cannot change, and causes the spacing of every mouthful of well rig floor lower plane and blowout preventer main body to change greatly, and needs to make new conduit according to on-site actual situations; 3, after platform well construction drags derrick, pithead position has sent out change, but circulating tank position does not change, cause angle between well head and vibrosieve excessive, conduit liquid outlet direction can only rely on adjustment position, screw hole hole to carry out adjusting angle, precision is not high, cannot reach best angle; 4, truck-mounted drilling rig bushing height is lower, completion is got rid of when tearing blowout preventer open because working space is not enough, frequent employing gas welding abolishes conduit to reach the object conveniently completing and get rid of and tear operation open, and operating personnel stands in blowout preventer main body upper end and uses gas welding cutting catheter security risk very big.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of telescopic wellhead slurry umbrella device, the arrangement achieves the adjustment of catheter body height retractable, liquid outlet angle can rotate adjustment arbitrarily, integral type slurry basket, dismounting Portable safety, improve and receive fluidity energy, improve blowout preventer main body to correct and fixed standard level, reduce and labour intensity is installed, for getting rid of the effective operation space of tearing blowout preventer operation open and providing larger, cost-saving, increase work efficiency.The catheter length overcoming existing well head pipe guide is fixed, and conduit liquid outlet direction can only rely on adjustment position, screw hole hole to carry out adjusting angle, inaccuracy, the unsafe deficiency of dismounting.
Technical solution adopted in the utility model is: a kind of telescopic wellhead slurry umbrella device, comprises lower standing tube; Lower standing tube lower end mounting flange, upper riser lower end can be elevated and rotate in lower standing tube, and upper riser lower end is connected lower standing tube and fixed by jackscrew, upper riser sidewall connects mud liquid back pipe, upper riser top connects slurry basket, and upper riser and lower standing tube sidewall are all designed with hanger.
The beneficial effects of the utility model are: the utility model achieves the adjustment of catheter body height retractable, liquid outlet angle can rotate adjustment arbitrarily, integral type slurry basket, dismounting Portable safety, improves and receives fluidity energy, improves blowout preventer main body and corrects and fixed standard level, reduce and labour intensity is installed, for getting rid of the effective operation space of tearing blowout preventer operation open and providing larger, cost-saving, increase work efficiency.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of telescopic wellhead slurry umbrella device, comprises lower standing tube 1; Lower standing tube 1 lower end mounting flange, upper riser 2 lower end can be elevated and rotate in lower standing tube 1, upper riser 2 lower end is connected lower standing tube 1 and is fixed by jackscrew, upper riser 2 sidewall connects mud liquid back pipe 3, upper riser 2 top connects slurry basket 4, and upper riser 2 and lower standing tube 1 sidewall are all designed with hanger.
The utility model can freely up and down be elevated, and again can not make conduit because required duct height changes.Due to height adjustable, therefore can ensure that liquid outlet pipe height is at utmost higher than guiding gutter, prevent mud from flowing backwards, sand removal is effective, not easily suppresses stifled.Upper riser 2 lower end can rotate freely in lower standing tube 1, and mud liquid back pipe 3 can be aimed at arbitrarily angled, and adjustment angle is accurate, simple to operation.In well site, condition is limited, and well head cannot be just fairly obvious to effect in elevated trough or platform well construction.Upper riser 2 and lower standing tube 1 sidewall are all designed with hanger, lower standing tube 1, upper riser 2, slurry basket 4 can freely decompose, integral hoisting also detachable split can be realized, evaded dismounting, lifting risk, stopped the risk employed electrogas welding because installing conduit and exist in well head.Because conduit can freely be elevated, therefore can reduce gap between slurry basket and brill dish lower surface to greatest extent, effectively prevent mud excessive, ensure blowout preventer hygiene.The utility model has evaded the security risk in installation and removal operation, improves operating efficiency, reduces labor strength, low cost of manufacture.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
