Abstract
An internally sealed order switch of water exploration and water shut off belongs to an in-silo petroleum tool in an oil field. The inner side of an upper joint 1 which is provided with a sealing rubber ring 9 is hermetically connected with a lower joint 2; the lower joint 2 is internally connected with a piston 3 which is provided with seal rubber rings 4 and 5; the outer side of the lower joint 2 is provided with track slots 8; sliding pins 10 are hung in the track slots 8, and the sliding pins are connected with a one-way valve 12 which is provided with a sealing rubber ring 11; the upper joint 1 and the lower joint 2 are internally connected with the piston 3 which is connected with the one-way valve 12 in the lower position to form a sealed ring cavity 7; a spring 6 is pressed in the sealed ring cavity; the track slots 8 on the outer side of the lower joint 2 are four V-shaped guiding slots 8-1, three long track slots 8-2 and one short track slot 8-3; the guiding slots, the long track slots and the short track slot are connected in the dislocation mode; an inclination angle is from 20 DEG to 60 DEG; reversing pressure is 14MPa; working pressure is 25MPa. The utility model is matched with a water shut off packer and is suitable for the oil extraction operation of water exploration and water shut off in an oil well.
Description
Affiliated technical field the utility model belongs to down-hole, oil field petroleum tool, and particularly a kind of inner sealing is looked for the water blockoff sequence switch.
Background technology is present, and the home and abroad oilfield exploitation intermediary and later stages, interval is many in the well, oil reservoir, water layer are arranged, need to adopt water detection, water plugging string, water layer, oil reservoir are found out, the shutoff water layer, the exploitation oil reservoir, looking for the water blockoff sequence switch is exactly the key tool of this tubing string.The existing water blockoff sequence switch commutation component facade of looking for is exposed, uses the long-pending sand in one section rear surface, fouling in well, and it is dumb to commutate, and serious meeting causes whole tubing string out of control, the operation failure.
The summary of the invention the purpose of this utility model is to overcome above technical deficiency, provides a kind of commutation parts to be sealed in tool interior, and the inner sealing of commutation flexibility and reliability is looked for the water blockoff sequence switch.
The utility model task is, the top connection inner seal that inner sealing looks for the water blockoff sequence switch that O-ring seal is installed connects lower contact, connect the piston that O-ring seal is installed in going up, the sliding pin that articulates in the lower contact arranged outside track groove is connected with the one way valve that O-ring seal is installed, take over a job in top connection and the lower contact plug, connect one way valve down and constitute crimp spring in the sealing ring cavity, lower contact outer tracks groove is that 4 " V " font gathering sills, 3 long track grooves are connected with 1 short track groove dislocation, and the angle of slope is 20-60 °.
The utlity model has following characteristics: one, the commutation parts are sealed in tool interior, do not contact with external environment, and commutation is flexibly; They are two years old, the track groove is that 4 " V " font gathering sills, 3 long track grooves are connected with 1 short track groove dislocation, and the angle of slope is 20-60 °, and sliding pin is after long track groove or short track groove enter gathering sill and arrive the summit, enter next long track groove or short track groove along opposite side, commutation is reliable.
Description of drawings specifies with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows that inner sealing looks for water blockoff sequence switch structure.
Fig. 2 show the track groove along A to expanded view.
Among the figure, the 1-top connection; The 2-lower contact; The 3-piston; The 4-O-ring seal; The 5-O-ring seal; The 6-spring; 7-seals ring cavity; 8-track groove; The 8-1-gathering sill; The long track groove of 8-2-; The short track groove of 8-3-; The 9-O-ring seal; The 10-sliding pin; The 11-O-ring seal; The 12-one way valve
The specific embodiment is with reference to accompanying drawing 1, inner sealing is looked for the lower contact 2 that is tightly connected of the top connection 1 upper end screw thread of water blockoff sequence switch, middle install piston 3, down connect spring 6, connect one way valve 12 down, connect sliding pin 10 in the one way valve 12 and be connected the O-ring seal of installing in the top connection 19, lower contact 2 with the track groove 8 in lower contact 2 outsides, the O-ring seal of installing on the piston 34,5, the O-ring seal of installing on the one way valve 12 11 constitutes sealing ring cavity 7, interior crimp spring 6.With reference to accompanying drawing 2, track groove 8 is that 4 " V " font gathering sill 8-1,3 long track groove 8-2 are connected with 1 short track groove 8-3 dislocation, and the angle of slope is 20-60 °.
Inner sealing is looked for the water blockoff sequence switch course of work: oil pipe-packer-inner sealing looks for water blockoff sequence switch-oil pipe-packer-inner sealing to look for water blockoff sequence switch-oil pipe-packer-inner sealing to look for water blockoff sequence switch-dead blocking up, the arrival desired location of going into the well, water filling pressurization in oil pipe, up at action of hydraulic force one way valve 12, compression spring 6, it is up at track groove 8 to drive sliding pin 10, piston 3 is up under the 7 internal pressure effects of sealing ring cavity, when pressure reaches commutation pressure, sliding pin 10 is during to gathering sill 8-1, and after the pressure release, spring 6 presses down one way valve 12, sliding pin 10 slips into subordinate's track groove at gathering sill 8-1, piston 3 is descending in the effect of instrument external pressure, and sliding pin 10 is when long track groove 8-2, and instrument is in closed condition, sliding pin 10 is when weak point track groove 8-3, and instrument is in opening.
Inner sealing is looked for water blockoff sequence switch technical performance index:
Commutation pressure 14MPa
Operting differential pressure 25MPa
Inner sealing is looked for water blockoff sequence switch and the supporting use of Packer for blocking water, is applicable to oil well water detection, water blockoff oil producing operation.
