The body of the utility model is a three-way body, the two straight ends are connected with a water distributing pipeline, a water nozzle is arranged in the water nozzle body, and the water distributing nozzles with different standards can be selected according to the water injection quantity of a single well per day of the water injection wells. The water distributing nozzles can be simply exchanged by a special tool, the utility model is fixedly arranged in a water distributing station, the changing of the water distributing nozzle can not be restricted by environmental condition, and the utility model can avoid frequently opening and shutting the gate valve and can accurately injecting water. The utility model has simple structure and convenient operation.

Description

Ground water distributor for water filling well

A kind of water injection well ground injection well downhole flow regulator that relates to oil-field flooding is ground, an a kind of oil field water dispensing apparatus.

In the prior art, water injection well in oil fields individual well water injection rate is controlled by the high pressure slide valve, and the water injection well water distribution all is the high pressure water injection system, the well head water injection pressure reaches 30.0～35.0mPa, high pressure slide valve frequent unlatching under like this high pressure carried out Flow-rate adjustment, not only can not be regulated flow exactly and make slide valve sting evil idea in very short time and scrap, often change slide valve, not only cause economically loss, also directly influenced crude oil output.

The purpose of this utility model be according to water injection well day the individual well water injection rate what adopt the water distribution mouth of different size to satisfy its water injection rate requirement, can be by the accurate water distribution of water injection well water distribution quantity requirement, avoided frequent unlatching slide valve, prolonged application life of valve.

The purpose of this utility model is achieved in that

The utility model structure such as Fig. 1 comprise water distribution main body 1, water distribution mouth 2, faucet body 3, gland 4, sealing ring 5; Faucet body 3 structures such as Fig. 2, comprise bayonet socket 6, groove 7, water distribution mouth 2.Water distribution main body 1 of the present utility model is a three-way body, and its two straight-through end is connected with the water distribution pipeline, bypass ends is used to pick and place faucet body 3, its end face gland 4, have sealing ring 5 to seal therebetween.Water distribution main body 1, straight pipe center have faucet body 3 to embed in the water distribution main body 1, faucet body 3 is that the bypass pipe from water distribution main body 1 takes off gland 4 and picks and places, there is bayonet socket 6 to embed on the faucet body 3, in the water distribution main body 1 be sealed and matched, picking and placeing groove 7 and be the centre bore that special-purpose fetching tool hook picks and places faucet body 3, faucet body 3 thereon has a snap ring that itself and water distribution mouth 2 are sealed and matched, water distribution mouth 2 bores have various different sizes, according to water injection rate what, select the water distribution mouth 2 of different size for use.

The utility model is simple in structure, compact, easy for operation, and water distribution quantity is accurate, cost is low, good in economic efficiency.

In conjunction with Fig. 1 and Fig. 2 the utility model is further described:

Fig. 1 is a water injection well ground injection well downhole flow regulator structure chart;

Fig. 2 is the faucet body structure chart.

This device comprises water distribution main body 1, water distribution mouth 2, faucet body 3, on bayonet socket 6 is arranged, groove 7, water distribution main body 1 is a three-way body, its siphunculus one end is threaded with the water distribution pipeline, the another port is fluted, pipeline snaps in the groove, be tightly connected with pipeline, bypass ends seals with gland 4 and sealing ring 5, the straight pipe center of water distribution main body 1 is embedded in it by faucet body 3, faucet body 3 is that the bypass pipe from water distribution main body 1 takes off gland 4 and picks and places, bayonet socket 6 is arranged on the faucet body 3, embed in the water distribution main body 1 and cooperate with body seal, groove 7 is that special-purpose fetching tool is used, in the centre bore of faucet body 3 snap ring is arranged, itself and ceramic water nozzle 2 are sealed and matched, water distribution mouth 2 has various different sizes, and lowest calibre is 1.0mm, but water supply flow is 0.25～0.29m ³/ h, water pressure resistance are 40～50MPa, are 8.33m but maximum caliber is the 7.0mm water supply flow ³/ h, according to the water injection well water requirement what, select for use different size water distribution mouth 2, utilize special tool can change water distribution mouth 2, this injection well downhole flow regulator simply to be installed in the distributing room for water injection, to change that the water distribution mouth is not subjected to the ambient conditions restriction, avoids frequently opening and closing slide valve, injection allocation water exactly, improve workman's condition of labor, improved economic benefit.

Claims
