Background technology
At present, the oil well groundwater prospecting method is more, can divide steel wire operation switch production mandrel method, chemical shoulder rotation, temperature and pressure method, hydraulic control switch, electric-controlled switch, mode water detection such as look for stifled generation, generally needs to go up workover rig during operation, and construction is complicated; The most frequently used groundwater prospecting method has three kinds at present, hydraulic control water detection switch is by making the commutation of down-hole water detection switch realize water detection from tubing string or the pressurization of oil jacket annular space, because of hydraulic selector is sealed the influence of formation pressure and ground pump truck pressure oscillation, reliability is relatively poor; Automatically controlled water detection switch has two kinds of On-line Control and down-hole microcomputerized control, and one time the water detection input cost is higher, generally use a period of time after, need in time trip out the water detection instrument, limit applying of this technology.
Summary of the invention
The purpose of this utility model is that existing water detection technology construction operation is complicated in order to overcome, investment is unfavorable for the deficiency applied greatly, and provide a kind of three layers of wheel of sucker rod control to take out the water detection switch, it is mechanical water detection technology that three layers of wheel of this sucker rod control are taken out the water detection switch, this water detection technology is to be lowered to the water detection switch with inspection pump line post, just can reach by the dead space way of regulating pump during ordinary production the wheel of three oil reservoirs is taken out and closed and adopt, greatly reduce the water detection cost.
The technical solution of the utility model is:
The utility model is by main body, the control sliding sleeve, pump valve, packing element, slip ring, spring is formed, wherein packing element is arranged on the main body outside, the control sliding sleeve, pump valve, slip ring, spring is arranged on body interior, the last inlet opening of upper layer position is arranged on the top of packing element, the middle inlet opening of layer position, middle part and the following inlet opening of lower layer position are arranged on the bottom of packing element, the control sliding sleeve passes the pump valve that is arranged on body interior, slip ring is arranged on control sliding sleeve inside, bottom at the control sliding sleeve is provided with spring, in the bottom of pump valve, the main body external surface of the inside of control sliding sleeve offers commutation track groove.By pressure-controlled sliding sleeve under the sucker rod, the slip ring that is arranged on the control sliding sleeve commutates under the effect of commutation track groove, on when carrying sucker rod, under the effect of spring force, the control sliding sleeve is up, and locatees in the locating slot of track pipe, difference according to the position, inlet opening on the control sliding sleeve can directly be communicated with upper layer position, layer position, middle part, lower layer position respectively, also can all be communicated with three layer portions, realizes the branch of three layer positions is adopted and closed and adopt.
The course of work of the present utility model and principle are:
After going into the well, according to the residing position of control sliding sleeve, oil well is produced certain layer position earlier, after producing a period of time, to the liquid-producing capacity of this layer understanding more clearly after, transfer rod string, under the effect of sucker rod and oil pump plunger piston gravity, the control sliding sleeve is descending, be arranged on the slip ring of control on the sliding sleeve and under the effect of commutation track groove, commutate, on when carrying sucker rod, under the effect of spring force, the control sliding sleeve is up, and in the locating slot of track pipe, locate, according to the difference of position, the inlet opening of control on the sliding sleeve can be respectively and the upper layer position, layer position, middle part, the lower layer position directly is communicated with, also can all be communicated with, realize the branch of three layer positions is adopted and closed and adopt with three layer portions.
The packing element of the utility model main body outside is the compression packing element, adopts supporting way to realize setting.
Part described in the utility model; be the combination of a plurality of parts; done description and the protection that maximum simplification is beneficial to patent under the situation that does not influence the description of its principle and structure, the professional can design this water detection switch according to the description on the patent.
The beneficial effects of the utility model are: when the oil well upkeep operation, just can be with this water detection switch G.I.H, the dead space by regulating pump plunger from way, different payzones are switched, use very convenient.
