Abstract
The utility model relates to a lift short connecting type rotary operation water tap which is used on the well repairing operation of an oil water well of an oilfield. The utility model is composed of a composite lift short connection (1), a positioning pin (2), a bearing sleeve (3), a first-stage sealing ring (4), a thrust sphere bearing (5), a second-stage sealing ring (6), a centripetal thrust roller bearing (7), a dustproof sealing ring (8) and a bearing rotation connector (9). The water tap has a lift short connection structure, a double-stage sealing structure and a double-stage bearing structure. The utility model is convenient to lift. The utility model has the advantages of strong bearing capability and reliable rotation seal. The use of the utility model can enhance the capability and the efficiency of rotation operation in the well repairing process of the oil water well, enlarge the construction project of measure operation, reduce the labour strength of an operation worker and is favorable to the treatment of a drill clamping accident and safe production.
Description
Technical field:
The utility model relates to a kind of rotary sealing appts that is used for oilfield oil well spin rinse operation process.
Background technology:
Along with oil field development and the prolongation of oil-water well production time, comprise that the oil-water well workover treatment work amount of light maintenance operation increases day by day.At present, the on-the-spot water tap that uses of oil-water well workover treatment is divided into two types by hoisting way: the one, and suspension ring formula water tap, gooseneck is connected in the top of gland, suspension ring are fixed on the gland side by bearing pin, the bottom connects the thrust axis bearing sleeve, in have bearing and the carrying joint, the carrying joint in bearing holder (housing, cover), can rotate; The 2nd, promote the short connection type water tap, gooseneck is enclosed within top and promotes on the short circuit, adopts rubber sealing therebetween, the last lower house of bottom water receiving tap, the carrying thrust bearing is arranged in the lower house, and working solution enters lifting short circuit inner chamber by gooseneck and imports to water tap inside, enters in the kelly bar then.Above-mentioned two types of water taps all exist the problem of poor sealing performance, and suspension ring formula water tap is that suspension ring are connected with the operation Hoisting System, can't promote with elevator, the trouble of seting out, and suspension ring and bearing pin intensity are lower, and housing adopts casting processing, and intensity is lower; Though second kind has been adopted the lifting short circuit, can adopt elevator to be connected lifting with Hoisting System, be drilled with side opening in the gooseneck position, and diameter is less, has a strong impact on the supporting capacity that promotes short circuit, again because of the rubber sealing poor-performing, often leak, be unfavorable for normally carrying out of workover treatment.
Summary of the invention:
The purpose of this utility model is to provide a kind of and is convenient to promote when the oil-water well workover treatment and supporting capacity is strong, the lifting short connection type spin rinse operation water tap of good seal performance.
The utility model is to realize like this.This kind workover treatment is made up of compound lifting short circuit, shop bolt, bearing holder (housing, cover), sealing ring, thrust ball bearing, centripetal thrust force roller bearing, load-carrying swivel joint with water tap, the outside, compound lifting short circuit bottom is connected with bearing holder (housing, cover) top with shop bolt by screw thread, and the inner headed face lower end is relative with the load-carrying swivel joint upper end; Be respectively equipped with primary seal circle and secondary seal circle in compound lifting short circuit bottom inner headed face and the load-carrying swivel joint top periphery seal groove, be provided with dust-proof seal ring in the periphery seal groove of load-carrying swivel joint bottom; Load-carrying swivel joint periphery shoulder upper and lower is respectively equipped with thrust ball bearing and centripetal thrust force roller bearing.This kind spin rinse operation water tap is the indispensable instrument that is rotated operation in the oil well repairing operation construction, is mainly used in that rotary sleeve mills, milling and the construction of brill ash plug.By water tap hose and kelly bar are coupled together, working solution are delivered to the brill miller tool of drilling rod lower end, in normal well-flushing, rotary drill column limit, limit transfer or on carry drill string, carry out milling, cover mills, bores constructions such as grey plug.Use this kind water tap milling or when creeping in oil-water well workover treatment process, it is firm earlier hose to be connected with gooseneck on the compound lifting short circuit, hangs lifting short circuit (the water tap bottom connects kelly bar) with elevator again; After mentioning water tap and kelly bar, allow the kelly bar pin thread be connected the back test with well head drilling rod box and to apply the pressure of the drill 10～20KN and carry out abrasive drilling.At this moment, the water tap external shell does not change, have only kelly bar to drive down-hole equipment rotation milling, drill string load is added on the centripetal thrust force roller bearing by swivel joint in most of well, guarantee that drill string can normally rotate milling or creep in the situation of carrying is gone into the well, the twin-stage sealing then makes the rotatory sealing of water tap more reliable.
The utlity model has the sealing of lifting short circuit and twin-stage, twin-stage bearing arrangement, be convenient to promote, and supporting capacity is strong, rotatory sealing is reliable, utilize it can improve the ability and the efficient of rotary operation in the oil-water well well workover process, expansion measure job execution project, and can reduce operating worker labour intensity, help lock of tool drilling processing and safety in production.
