Abstract
The utility model relates to a vapor-proof sand settling device used for the separation of vapor-liquid sand in an oil well, and the vapor-proof sand settling device comprises an upper tie-in, an outer tube, an inner tube and a lower tie-in. The big screw thread on the lower part of the upper tie-in is connected with the upper part of the outer tube in a screw thread way. The screw thread on the lower part of the outer tube is connected with the lower tie-in; the small screw thread on the lower part of the upper tie-in is connected with the upper part of the inner tube. A connection hole is arranged under the screw thread on the upper part of the outer tube; the lower part of the lower tie-in is provided with an outside thread, and the inner of the lower tie-in is provided with a through hole. The vapor-liquid sand flows along the connection hole downwards, and then upwards flows into an oil-well pump from the bottom of the inner tube; the vapor which is separated when flowing in a turning way enters into a sleeve through the connection hole without entering into the oil-well pump, thereby can reduce the vapor which enters into the oil-well pump, enhance the pump efficiency of the oil-well pump, and improve the economic benefit of the oil well. The inner of the lower tie-in is provided with the through hole, thus the separated sand can be immersed into a sand settling tail tube positioned under the lower tie-in, and a lower entrance of the inner tube cannot be blocked up, therefore, the oil well can normally produce for a long time.
Description
One, technical field
The utility model belongs to the instrument that oil well is used, particularly a kind of gas-tight sand setting device.
Two, background technology
In oil well, the well air content that has is big, and when pumping with oil well pump, the gas-liquid ratio that enters in the oil well pump is big, reduces well liquid discharge capacity, and oil well output is low, and pump efficiency is low, and after air content surpassed certain value, oil well pump also gas lock can take place, and causes oil well not fuel-displaced.In order to reduce the influence of gas to oil well pump work, the oil field is often adopted to install under pump and is utilized the gas anchor of slippage effect and Gravity Separation simply to separate, prevent that gas from entering in the pump, though this gas anchor has effect, but shut present gas anchor bottom, and pipe bottom inlet caused oil inlet passage blocked in the sand of separating stopped up easily, oil well is not fuel-displaced, and the economic loss tool is big.
Three, summary of the invention
The purpose of this utility model provides a kind of gas-tight sand setting device, is installed under the oil well pump in the pumpingh well, and gas-liquid sand is separated, and reduces the gas that enters oil well pump, improves the pump efficiency of oil well pump, prevents that sand from burying fluid course, improves the oil well economic benefit.
The purpose of this utility model is achieved in that by top connection, outer tube, interior pipe, lower contact to be formed, top connection bottom major thread and outer tube top thread connection, the outer tube lower thread connects with lower contact, top connection bottom minor thread connects with interior pipe top, under the screw thread of outer tube top linked hole is arranged, external screw thread is arranged at the lower contact bottom, and there is through hole lower contact inside.
The beneficial effects of the utility model are: gas-liquid sand upwards flow in the oil well pump from interior pipe bottom downwards from linked hole, gas enters sleeve pipe from linked hole turning to be separated when flowing, do not enter in the oil well pump, reduce the gas that enters oil well pump, improve the pump efficiency of oil well pump, improve the oil well economic benefit.Because there is through hole lower contact inside, the sand of separating can sink in the sand setting tail pipe under the lower contact, and interior pipe bottom inlet is not blocked, and oil well can long-term ordinary production.
Four, description of drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As shown in the figure, form by top connection 1, outer tube 2, interior pipe 4, lower contact 5, top connection 1 bottom major thread and outer tube 2 top thread connection, outer tube 2 lower thread connect with lower contact 5, top connection 1 bottom minor thread connects with interior pipe 4 tops, under the outer tube 2 top screw threads linked hole 3 is arranged, external screw thread is arranged at lower contact 5 bottoms, and there is through hole lower contact 5 inside.
Gas-liquid sand enters from linked hole and flows downward, change when flowing to, gas separates in the sleeve pipe to last outflow, and the liquid sand after the separation continues downwards, under action of gravity, sand is separated from mixed liquor and is sunk to the bottom tail pipe, and liquid stream upwards flow in the oil well pump from interior pipe bottom, and gas and sand do not enter in the oil well pump, the gas and the sand that enter oil well pump have been reduced, eliminated the influence of gas and sand, thereby improved oil well pump pump efficiency, the work period of the long oil well pump in the court of a feudal ruler oil well pump work.
