Abstract
The utility model relates to a well washing shunt switch, consisting of an upper joint, a valve group, a connection tube, a shunt joint and a lower joint. The lower part of the upper joint is connected with the upper part of the connection tube; the lower part of the connection tube is connected with big threads of the upper part of the shunt joint; the lower part of the shunt joint is connected with the lower joint; the valve group is connected with small threads of the upper part of the shunt joint; the shunt joint is provided with a well washing channel and a vertical liquid inlet channel; the upper joint is provided with oil pipe female threads, and the lower part of the lower joint is provided with oil pipe male threads; and the vertical liquid inlet channel is a circular arc slotted hole. Liquid in a sleeve pipe can enter from the well cleaning channel, but well liquid can not flow out of the well cleaning channel, stratigraphic oil flow can not enter the sleeve pipe, and oil can not flow out of the sleeve pipe no matter how high the well pressure is, therefore, the stealer can not drain oil from the sleeve pipe to steal the oil.
Description
Technical field:
The utility model is the instrument that oil well is used, and is a kind of well-flushing diverting switch.
Background technology:
Because formation leakage, for normal well-flushing, generally divide into a packer and UNICOM's screen casing at tubing string, but UNICOM's screen casing can not be controlled the flow direction, well liquid can enter sleeve pipe through UNICOM's screen casing, and when oil well pressure was high, well liquid can flow out in sleeve pipe, the thief stolen of can draining the oil at the sleeve pipe place causes the crude oil loss.
Summary of the invention:
The purpose of this utility model is a kind of well-flushing diverting switch of design, replaces existing UNICOM screen casing, can well-flushing, can blowout prevention, and the oil well production time is long, the thief stolen of can not draining the oil.
The purpose of this utility model is achieved in that by top connection, valve group, connecting tube, tap, lower contact to be formed, the top connection bottom connects with connecting tube top, the connecting tube bottom connects with tap top major thread, the tap bottom connects with lower contact, the valve group connects with tap top minor thread, and well-flushing passage and vertical feed pathway are arranged on the tap.
The female spiral shell of oil pipe is arranged in the top connection, and the public spiral shell of oil pipe is arranged at the lower contact bottom.
Vertical feed pathway is an arc-shaped slot.
The beneficial effects of the utility model are: liquid can enter through the well-flushing passage in the sleeve pipe, well liquid can not return out from the well-flushing passage, so formation oil stream can not enter in the sleeve pipe, pipe well is not pressed with many height and can flow out in sleeve pipe, the molecule that can the avoid theft stolen of draining the oil at the sleeve pipe place.
Description of drawings:
Accompanying drawing 1 is the assembling drawing of the utility model embodiment.
Accompanying drawing 2 is the sectional views after cutting open from A-A in the accompanying drawing 1.
The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As seen from Figure 1, the utility model is made up of top connection 1, valve group 2, connecting tube 3, tap 4, lower contact 5, top connection 1 bottom connects with connecting tube 3 tops, connecting tube 3 bottoms connect with tap 4 top major threads, tap 4 bottoms connect with lower contact 5, valve group 2 connects with tap 4 top minor threads, well-flushing passage 7 and vertical feed pathway 6 is arranged, as shown in Figure 1, 2 on the tap 4.The female spiral shell of oil pipe is arranged in the top connection 1, and the public spiral shell of oil pipe is arranged at lower contact 5 bottoms.Vertical feed pathway 6 is an arc-shaped slot, and passage is big, can not pile up foreign material, can sand setting.Well liquid upwards flows through vertical feed pathway 6, can not return out from well-flushing passage 7 under the effect of valve group 2, and during well-flushing, well-flushing water can enter upwards to flow out from well-flushing passage 7 realizes the oil well well-flushing.
