Description
Technical field
The utility model is the downhole tool of oilfield production usefulness, is the device for separating of gas and sand grains, specifically is a kind of pumpingh well sand setting gas anchor.
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 after air content surpassed certain value, oil well pump also gas lock can take place, and causes oil well not fuel-displaced.In oil well, the well sand content height that has, sand grains enter and cause the oil well pump wearing and tearing in the oil well pump, meeting holddown when serious, and oil well pump can not be worked, and necessary workover treatment reduces oil well output, needs a large amount of operating costs, the oil well deficiency in economic performance.In order to reduce gas, sand to the influence of oil well pump, the oil field is often adopted gas anchor or the sand anchor that utilizes slippage effect and Gravity Separation is installed under pump, simply separates, and prevents that gas, sand from entering in the pump.Though have certain effect, big for air content, shake out the oil well weak effect serious, though the multistage separating gas anchor of field by using, sand anchor result of use are good, complex structure, cost of production height.
Summary of the invention
The purpose of this utility model provides a kind of pumpingh well sand setting gas anchor, and gas sand is separated, and reduces the gas and the sand grains that enter oil well pump, improves the pump efficiency of oil well pump, reduces or eliminates sand grains to the infringement of oil well pump, prolongs the production cycle property of oil well.
The purpose of this utility model is achieved in that and comprises top connection, outlet valve, tube connector, last urceolus, big envelope, interior pipe, conduit, tap, transition joint, the core pipe, following urceolus, outlet valve is installed in the top of urceolus, tube connector passes the outlet valve rear lower and is connected with the top of conduit, the top of tube connector is connected with top connection, the bottom of conduit is connected with the top of tap, interior pipe is in the conduit, between interior pipe and the conduit interior annular space is arranged, big envelope is installed on interior pipe top, lead channel is arranged at the top of conduit, big envelope is on the lead channel, the upper end of annular space in big envelope stops up, make enter from lead channel in the liquid of annular space can only flow downward, last urceolus is enclosed within outside the conduit, outer annular space is arranged between last urceolus and the conduit, blind hole is arranged at the tap bottom, the side has portals, the tap bottom is connected with the upper internal threaded of transition joint, last urceolus bottom is connected with the upper external thread of transition joint, outer annular space communicates with the blind hole of tap bottom by portalling, the lower internal thread of transition joint is connected with the top of core pipe, the lower external thread of transition joint is connected with the top of following urceolus, form annular space down between core pipe and the following urceolus, UNICOM's groove is arranged at the top of following urceolus.
The beneficial effects of the utility model are: well liquid enters has secondary to turn in the utility model, gravitational difference between gas, sand, liquid and slippage effect are realized efficient separation the between liquid, gas, sand, the gas and the sand grains that enter oil well pump have been reduced, improved the pump efficiency of oil well pump, reduce or eliminate sand grains to the infringement of oil well pump, can prolong the production cycle property of oil well, improve the oil well economic benefit.
