Description
Technical field
The utility model belongs to the petroleum drilling engineering technical field.Being a kind of plug valve that gas passage and fluid passage are arranged that is connected on the double-deck kelly bar, is a kind of manual plug valve of controlling drilling tool compressed air and drilling fluid passage simultaneously.
Background technology
At present, in drilling engineering, what the overwhelming majority adopted is direct circulation drilling fluid boring method.The drilling fluid of this boring method arrives the shaft bottom by water tap, upper kelly cock valve, kelly bar, lower kelly cock, drilling rod, drill bit, and through the drilling rod outer ring space, is recycled to ground.The effect of upper and lower kelly cock is: blowout takes place in drilling process, can be rapidly the ball valve of plug valve be revolved and turn 90 degrees, close fluid passage in the drilling rod, reach the purpose of blowout in the control drilling rod.Existing plug valve has only a fluid passage, can only control liquid in the drilling rod, so relatively simple for structure.Its structure is that a cylindrical housings is arranged, and housing one end has the drilling tool internal thread, and the other end has the drilling tool external screw thread.Upper valve base and lower valve base are arranged in the housing, ball valve is arranged in the middle of upper valve base and the lower valve base.On upper valve base, lower valve base and the ball valve fluid passage is arranged.The fluid passage diameter is between the 50-80 millimeter.Be fixedly upper valve base, lower valve base and ball valve, between upper valve base and housing, retainer ring arranged.Ship and resell on another market in the hole of shipping and reselling on another market in the hole of shipping and reselling on another market on housing.The end of shipping and reselling on another market has the square cotter head, and the other end has the square cotter hole.The square cotter head inserts in the slot of shipping and reselling on another market of ball valve.The square cotter head of shipping and reselling on another market drives ball valve and rotates, can the switch cock valve, control effectively that drilling fluid passes through in the drilling rod.Original kelly cock has only a fluid passage, can only adapt to the needs of direct circulation drilling well.In the drilling technology a kind of new method is arranged now, be called counterflush drilling.This boring method requires can not only pass through liquid in the drilling tool, also will pass through gases at high pressure simultaneously.Original kelly cock can not adapt to the requirement of drilling well new method.
The utility model content
The purpose of this utility model is: overcome the shortcoming that original technology kelly cock has only a fluid passage.Change the structure of original kelly cock, increase gas passage.Design gas passage and the isolated binary channels plug valve of fluid passage overcome the shortcoming that original kelly cock can not adapt to counterflush drilling.
The binary channels plug valve is achieved in that upper valve base, lower valve base and ball valve in the housing.Plug socket is arranged at upper valve base top, and plug socket is cylindric.The plug socket inwall has joint ring.Connection-peg is arranged at the lower valve base bottom, and connection-peg is cylindric.Gas passage is arranged around the fluid passage on upper valve base, lower valve base and the ball valve.On the sphere of ball valve and upper valve base, lower valve base contact surface, joint ring is arranged.
Effect of the present utility model: the binary channels plug valve has fluid passage and gas passage on upper valve base, lower valve base and ball valve, makes drilling fluid and compressed air can pass through the binary channels plug valve simultaneously, and gas passage and fluid passage are isolated.In when, blowout taking place need close when, closing liquid passage and gas passage simultaneously, drilling fluid and compressed air can not pass through.On upper valve base top plug socket is arranged, the plug socket inwall has joint ring, and connection-peg is arranged at the lower valve base bottom.When double-deck drilling tool connected with the binary channels plug valve, the connection-peg of upper part of double drilling tool inserted in the binary channels plug valve plug socket; Binary channels plug valve connection-peg inserts the plug socket of the double-deck drilling tool in bottom.Forming the passage of drilling fluid and gas barrier, adapt to the requirement of counterflush drilling with double-deck drilling tool connection place.
