Abstract
An underground water mixing device comprises an upper joint, a throttling water nozzle, a valve cover, a spring, a valve ball, a valve seat, an outer pipe, a valve seat joint, a shunt joint and a lower joint. The lower part of the upper joint is connected with the upper part of the outer pipe, the lower part of the outer pipe is connected with the upper part of the shunt joint through large threads, the lower part of the shunt joint is connected with the lower joint, the lower part of the throttling water nozzle is connected with the upper part of the valve cover, the lower part of the valve cover is connected with the upper part of the valve seat joint, a spring, a valve ball and a valve seat are arranged in the valve cover, and the lower part of the valve seat joint is. During production, the thick oil in the thick oil layer is mixed with the liquid in the water outlet layer to dilute the thick oil. After the fluid of the water outlet layer is controlled by the throttle valve, the pressure and the flow are reduced, and the oil outlet of the thick oil layer cannot be influenced. Therefore, when the thick oil layer and the water layer are exploited simultaneously, the thick oil layer is not interfered, the thick oil is diluted, the exploitation of the thick oil is facilitated, the oil yield of the oil well is large, the normal production can be realized without adopting viscosity reduction measures such as thermal extraction, and the economic benefit is high.
Description
One, technical field
The utility model belongs to the down-hole water mixing device that oil field machinery oil is used.
Two, background technology
Oil field pumping well generally all has the plural liquid layer position that goes out, the layer that has is an oil reservoir, the layer that has is high aquifer, the layer that has is complete water-yielding stratum, oil is very thick in the oil reservoir that has, do not take to produce difficulty of heavy oil tested layer separately as the viscosity reduction measure of thermal recovery and so on, and take the viscosity reduction measure cost height as thermal recovery and so on, the exploitation benefit is low.Can open for the well that guarantees viscous crude and to take out production, have only heavy oil tested layer and water layer are exploited simultaneously, because the flowability of viscous crude is poor, thereby heavy oil tested layer stratum flowing pressure is low, and when heavy oil tested layer and water-yielding stratum were exploited simultaneously, oil pump capacity was few, and water yield is many, deficiency in economic performance.
Three, summary of the invention
The purpose of this utility model is a kind of down-hole water mixing device of design, its water-yielding stratum and heavy oil tested layer are mixed when producing, the water-yielding stratum water yield is controlled, heavy oil tested layer fully discharges, be not subjected to the interference of water-yielding stratum, viscous crude obtains dilution, the energy ordinary production, and the well oil output height, the economic benefit of raising oil well.
The purpose of this utility model is achieved in that it is made up of top connection, throttling water nozzle, valve bonnet, spring, valve ball, valve seat, outer tube, valve base joint, tap, lower contact.Top connection lower thread and outer tube top thread connection, the outer tube lower thread connects with tap top major thread, the tap lower thread connects with lower contact, throttling water nozzle bottom connects with valve bonnet top, the valve bonnet bottom connects with valve base joint top, mounting spring, valve ball, valve seat from top to bottom in the valve bonnet, the valve base joint bottom connects with tap top minor thread.
During production, the viscous crude of heavy oil tested layer upwards flows through lower contact, tap bypass, outer tube and valve bonnet annular space, the liquid of water-yielding stratum upwards flows after entering its central passage from the tap side, flow out and mixes through valve base joint, valve seat, valve bonnet, spring, throttling water nozzle, make viscous crude obtain diluting with viscous crude that the bottom flows into.Mix moderately for the water yield that guarantees water-yielding stratum, watering quantity is by the control of throttling water nozzle, and different watering quantities is controlled with different throttling water nozzles.By swivel flowing water mouth, can change amount of spring compression, realize different valve ball opening pressures.
The beneficial effects of the utility model are: because the fluid of water-yielding stratum is after throttle valve control, pressure, flow descend, and it is fuel-displaced that the pressure after the decline, flow can not influence heavy oil tested layer.Therefore, when heavy oil tested layer and water layer were exploited simultaneously, heavy oil tested layer can not be interfered, and viscous crude obtains dilution, helps the exploitation of viscous crude, and the oil well oil pump capacity is many, and need not take just can ordinary production as the viscosity reduction measure of thermal recovery and so on, the economic benefit height.
Four, description of drawings
Accompanying drawing is the schematic diagram of the utility model embodiment.
Among the figure: the 1st, top connection, the 2nd, throttling water nozzle, the 3rd, valve bonnet, the 4th, spring, the 5th, valve ball, the 6th, valve seat, the 7th, outer tube, the 8th, valve base joint, the 9th, tap, the 10th, lower contact.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment of the present utility model is made up of top connection 1, throttling water nozzle 2, valve bonnet 3, spring 4, valve ball 5, valve seat 6, outer tube 7, valve base joint 8, tap 9, lower contact 10.Top connection 1 lower thread and outer tube 7 top thread connection, outer tube 7 lower thread connect with tap 9 top major threads, tap 9 lower thread connect with lower contact 10, throttling water nozzle 2 bottoms connect with valve bonnet 3 tops, valve bonnet 3 bottoms connect with valve base joint 8 tops, mounting spring 4, valve ball 5, valve seat 6 from top to bottom in the valve bonnet 3, valve base joint 8 bottoms connect with tap 9 top minor threads.
During production, the annular space of the viscous crude of heavy oil tested layer between bypass A, outer tube 7 and the valve bonnet 3 of lower contact 10, tap 9 upwards flows, the liquid of water-yielding stratum upwards flows after entering its center channel B from tap 9 sides, flow out and mixes through valve base joint 8, valve seat 6, valve bonnet 3, spring 4, throttling water nozzle 2, make viscous crude obtain diluting with viscous crude that the bottom flows into.Mix moderately for the water yield that guarantees water-yielding stratum, watering quantity is by 2 controls of throttling water nozzle, and different watering quantities is controlled with different throttling water nozzles.By swivel flowing water mouth 2, can change the decrement of spring 4, realize different valve ball opening pressures.
