Description
Technical field the utility model relates to a kind of underground equipment, especially for water layer, oil reservoir under the detecting shaft, and the intelligent switch device that can carry out automatic shutoff to it.
Background technology is used for the switching device of oil reservoir under the detecting shaft, water layer, normally before going into the well, configure the time of opening valve and closing valve of each layer equipment, during detection, wherein one deck valve is an open mode, the valve of other layers is a closed condition, according to the liquid that different time sections is extracted out, can learn that just stratum, equipment place is an oil reservoir, or water layer.After surveying end, each layer equipment will all be opened drifting, then switching device is taken out, and descends dispenser that water layer is carried out shutoff again.The problem that exists is: because switching device does not have the shutoff function, therefore need secondary operation to carry out shutoff, both wasted time and energy, and the equipment and the operating cost that increase are higher.
The summary of the invention the purpose of this utility model is to provide a kind of intelligent switch device that can survey and can realize the multi-functional detection of shutoff and shutoff downhole oil, water layer.
The purpose of this utility model is achieved in that a kind of detection and shutoff downhole oil, the intelligent switch device of water layer, comprise by controller, motor, transmission mechanism, the detection agency that communicating valve and oil pipeline constitute, it is characterized in that also including the controlling organization that to realize automatic shutoff, this controlling organization is by being arranged on aboveground oil pumper as the control source, the sensing element that is used for measuring liquid flow is arranged on oil pipeline and is electrically connected with controller, controller can be discerned, receive the signal of telecommunication of sensing element feedback, output control machine operation realizes the signal of telecommunication of shutoff.
Described sensing element is pressure or pressure or flow or temperature pick up.
Described flow transmitter is to be made of magnetic rotatable part and Hall element.
What the utility model was identical with existing switching device is to survey underground oil reservoir, water layer, difference is can directly control shutoff automatically by switching device to the water layer that detects, and detection and shutoff process are controlled realization automatically by controller.Serial connection is arranged on oil or water the opening by controller control communicating valve of underground each layer switching device to its stratum of living in, close and survey automatically one by one, after obtaining a result, aboveground staff is according to the reserves of each layer oil, again valve is turn-offed shutoff, concrete shutoff process is: if close the wherein valve of one deck, realize shutoff, aboveground oil pumper is in opening, in the shutoff time that the controller of this layer switching device is set (being that controller can discerned the sensing element feedback signal during this period of time), sensing element will receive the signal feedback of liquid flow and give single-chip microcomputer, send instruction control machine operation by it, valve-off is realized shutoff.In at this moment, the controller of other layers switching device can not be discerned the feedback signal of sensing element, no control signal output, and motor is in off position.If one deck valve is not wherein carried out shutoff, aboveground oil pumper is in closed condition, being controller in the shutoff time that the controller of this layer switching device is set can discern the feedback signal of sensing element during this period of time, sensing element does not receive the signal feedback of liquid flow and gives controller, the output of controller no signal, valve keeps opening state.
Characteristics of the present utility model are: simple in structure, adopt hydraulic gear, and output is steady, power is big, when having detecting function, can also carry out shutoff automatically, a tractor serves several purposes reduces the operation number of times, reduced operation and cost of equipment widely, time saving and energy saving, stable and reliable for performance.This machine can be reused, and reduces cost.
Description of drawings Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of the utility model controller.
The specific embodiment is done further auspicious stating below in conjunction with accompanying drawing to the utility model:
As shown in Figure 1, the intelligent switch device of detection and shutoff downhole oil, water layer mainly is made of detection agency and shutoff controlling organization two parts.Detection agency comprises controller, micro machine, hydraulic gear, communicating valve.The shutoff controlling organization comprises the aboveground oil pumper in the flow transmitter, controller and the conduct control source that are made of magnetic rotatable part and resistant to elevated temperatures Hall element.Sensing element also can adopt resistant to elevated temperatures pressure, pressure and temperature pick up.Be disposed with battery pack 5, controller 1, micro machine 2, hydraulic jack 6, communicating valve 3, liquid sample storeroom 7 in the outer tube 4 of switching device from top to down.Battery pack and controller are arranged in the sleeve pipe 8, the upper end of sleeve pipe is provided with the plug 9 with port sealing, be provided with the rotatable part 11 of flow transmitter between plug and the top cap 10, rotatable part can be impeller or gear, its two ends are against on plug and the perpendicular gland 14 that supports of band by steel ball 12, and blade is provided with the magnetic patch 15 that is oppositely arranged with Hall element 13, and crown cap is established in the perpendicular end of supporting, gland, top cap are provided with oily passage 16, and top connection 17 is connected with outer tube.The lower end of sleeve pipe 8 is connected with tube connector 19 through transition joint 18, and the micro machine that sets within it is connected with leading screw 21 by shaft coupling 20, and shaft coupling is provided with bearing 22, to guarantee its even running.The lower end of tube connector is connected with the hydraulic jack of hydraulic gear, hydraulic jack is that different and cylinder body that be interconnected constitutes by two apertures, the bar portion of valve piston 24 stretches out outside the cylinder body and matches with leading screw, the bar portion of big piston 25 is connected with the spool 23 of communicating valve, and the cylinder body lower end is connected with valve body.Be evenly equipped with oil-out 27 on the valve body, oil-in 28 is established at the valve end center, valve body lower portion is connected with the single current valve 26 that constitutes liquid sample storeroom through reducer pipe 29, the bottom of single current valve is connected with lower end cap 31, the liquid outlet of single current valve is connected with the inlet of communicating valve through reducer pipe, its inlet is connected with inlet on being arranged on lower contact 30 through the through hole of lower end cap, and the inlet of single current valve is provided with the valve ball 32 that seals by spring 33 elastic force.The upper and lower joint that the two ends of outer tube are provided with can be connected with another switching device or pipeline.
