Abstract
The utility model relates to an automatic distributing valve in pit, it comprises top connection, check valve, valve ball, outer tube, main control mouth, lower clutch, and threaded connection is equipped with spring and sliding valve between check valve and main control mouth between top connection, check valve, outer tube, main control mouth and the lower clutch. The tool has the advantages of automatic gas distribution and self-regulation, and can fully utilize the casing associated gas resource to the oil pipe to lift oil, thereby reducing the leakage of the oil pipe and an oil pump, reducing the load in the oil pumping process, prolonging the service life of oil pumping equipment, improving the efficiency of the oil pump and the yield of the oil well, and the like.
Description
The utility model relates to a kind of down-hole automatic distributing valve, belongs to the oil and gas exploitation instrument.
In the existing machinery Production Wells process, oil reservoir associated gas resource wastes because of no production technology utilization (especially gas pressure resource), not only make the gas pressure resource can not get that utilization should be arranged thus, and existing oil production technology is for improving the oil pumping pump efficiency, have no alternative but exclusion sleeve gas as much as possible, thereby make crude oil in oil reservoir, just begin to occur degassing phenomenon, increased the oilfield exploitation difficulty, also influenced the recovery ratio in oil field simultaneously to some extent.
The purpose of this utility model is exactly a kind of automatic distributing valve of design on the oil pipe tubing string, and the sleeve pipe associated gas is imported in pit shaft behind the oil pipe can lifting crude oil, improves the pump efficiency of pumping.
The purpose of this utility model is achieved in that down-hole automatic distributing valve is made up of top connection, flap valve, valve ball, outer tube, master control mouth, lower contact, be threaded between top connection, flap valve, outer tube, master control mouth and the lower contact, constitute the framework of distributing valve, between flap valve and master control mouth, be provided with spring and guiding valve, above spring, be connected with adjusting nut, have air inlet in the lower contact with external pipe thread.
The utlity model has following advantage: 1, utilize the guiding valve on this instrument to realize automatic distributing and self-control; 2, sleeve pipe associated gas resource can be made full use of in the oil pipe in the fluid lifting, thereby reduce oil pipe, oil well pump leakage, reduce the load in the oil pumping process, prolong the application life of pumping unit, improve oil pumping pump efficiency and oil well output.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1: down-hole automatic distributing valve arrangement schematic diagram;
Fig. 2: distributing valve work schematic diagram;
Among the figure: 1-top connection, 2-flap valve, 3-valve ball, 4-adjusting nut, 5-spring,
6-outer tube, 7-guiding valve, 8-master control mouth, 9-air inlet, 10-lower contact;
11-sleeve pipe, 12-special-purpose pipe nipple, 13-eliminator;
Down-hole automatic distributing valve is made up of top connection 1, flap valve 2, valve ball 3, outer tube 6, guiding valve 7, master control mouth 8, lower contact 10, as shown in Figure 1.Be threaded between top connection 1, flap valve 2, outer tube 6, master control mouth 8 and the lower contact 10, constitute the framework of distributing valve, between flap valve 2 and master control mouth 8, be provided with spring 5 and guiding valve 7, adjusting nut 4 has been threaded with outer tube 6 below flap valve 2, it is used for compressing spring, thereby set the engaging pressure of guiding valve 7, have air inlet 9 in the lower contact 10.
In the normal use, combination is generally three to five to distributing valve in the down-hole, utilizes adjusting nut and master control mouth to configure the engaging pressure of guiding valve on the distributing valve on the ground.The top connection of distributing valve is inserted in the outer seat of honour of the special-purpose tube coupling of oil pipe, following outer interior jackscrew of special-purpose pipe nipple holds out against lower contact, make distributing valve become the external parts of special-purpose pipe nipple, the distributing valve top connection communicates with the special-purpose tube coupling seat of honour, as shown in Figure 2, special-purpose pipe nipple and the oil pipe tubing string joins and with oil pipe tubing string G.I.H, when the pressure of sleeve pipe associated gas rises to the pressure that can overcome the flap valve on the first order distributing valve, flap valve is opened automatically, implement normal distribution, the interior fluid column proportion of oil pipe constantly reduces after implementing normal distribution, thereby pressure reduction constantly increases in the formation oil pipe, when pressure reduction reaches second level distributing valve starting pressure, second level distributing valve is opened automatically, implement normal distribution, first order distributing valve reaches the closing presure of guiding valve because of pressure reduction simultaneously, at this moment guiding valve is upwards sealed the passage of distributing valve, close distributing valve, thereby the pressure resource is fully forwarded on the next stage automatic distributing point, distribution point constantly moves down in said process like this, thereby arrive on the automatic distributing valve of designing optimal distribution position, this valve is distribution in oil pipe continuously then, thereby guarantees making full use of of sleeve pipe gas.
