The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Figure 1 and Figure 2, this singly depresses the feed liquor controlling valve, comprise valve body, ground control system and valve regulator control system, described valve body comprises circuit board guard shield 1, motor shroud 2 and valve pocket 4, described circuit board guard shield 1 is threaded with described valve pocket 4, have axial passageway bridge 13 and side inlet opening 14 radially on the sidewall of valve pocket 4, described side inlet opening 14 is built-in with sensor 6 and sensor back of the body cap 5, axially passageway bridge 13 communicates with radially side inlet opening 14, and the upper end of passageway bridge 13 communicates with oil pipe; The centre bore internal thread fixed electrical machinery guard shield 2 of described valve pocket 4, the valve seat 12 that has through hole and connected valve seat back of the body cap 11, described motor shroud 2 is built-in with reducing motor, screw-nut body and spool 3, reducing motor, screw-nut body and spool 3 connect successively, the lower end of spool 3 can cooperate with the endoporus of valve seat 12, close or open the liquid pass hole 15 on the valve pocket 4, in addition, also have air equalizer opening 16 on the spool 3; The lower end of described valve pocket 4 is embedded with cable connecting arrangement, by glue pier 7, seal pressure cap 8, steel ball 9, depression bar screw 10 is formed, be used for stube cable, in the areole that shown seal pressure cap 8 embedding valve pockets 4 are held below, the inner of seal pressure cap 8 embeds glue pier 7, and the outer end embeds depression bar screw 10,10 on seal pressure cap 8 endoporus and depression bar screw are equipped with steel ball, penetrate cable in the centre bore of depression bar screw 10; Described valve regulator control system places in the above-mentioned circuit board guard shield 1, is connected by the reducing motor in motor drive module LM298 and the motor shroud 2, is electrically connected with described ground control system by the MAX485 chip interface.
This controlling valve is installed in automatically controlled closing and adopts tubing string lower floor, because its lower floor adopts feed liquor mode down, inlet can be added and be deep to the lower floor middle part, solving lower floor's producing fluid level descends fast, the problem of not enough suction, but and real-time continuous monitoring lower floor pressure, when lower floor's pressure descends fast not enough suction, can close controlling valve and recover this stressor layer, by the sensor in the side inlet opening, can ask for the every dynamic parameter in upper strata simultaneously.
The operating principle of above-mentioned controlling valve is: ground control system is transferred to regulating command in the chip STC12C5410AD in the valve regulator control system by the MAX485 interface by supervisory keyboard, the decoding back is to sending regulating command, drive the reducing motor rotating by motor drive module ML298, deceleration rear drive screw-nut body, push rod on the screw-nut body drives spool 3 actions, cooperate with the through hole of valve seat 12, close or open the inlet opening 15 of lower floor's feed pathway, realize that the continuous and quantitative of its aperture is regulated.The valve regulator control system judges by detecting the motor rotation blockage electric current whether valve is closed fully or opened: when valve is opened fully or fastened, motor generation stall, the electric current that flows through motor increases rapidly, surpassing testing circuit after a certain threshold value delivers to a high level in the chip STC12C5410AD in the valve regulator control system, system detects just thinks that valve closes fully or open behind this level, so reducing motor is closed, and control system report earthward.At this moment, the indicator lamp of corresponding each layer on off state will brighten on the display board that connects of ground control system and chip STC89C51RC.The pressure sensor 6 that is installed in side inlet opening 14 simultaneously can be monitored upper strata production fluid pressure in real time, and monitor signal is real-time transmitted to ground, reads by the display board playback, as shown in Figure 2.Adopt tubing string lower floor this controlling valve is installed automatically controlled closing, but just real-time continuous monitoring pressure and temperature are estimated the fluid situation of each fluid producing layer, can change according to pressure and regulate the controlling valve aperture in real time, control each layer production fluid amount, reduce interlayer interference.
