Abstract
The utility model relates to oil extracting machine equipment, which is the improvement of an oil-sand separator in specifically speaking. The utility model is characterized in that 10 meshes to 700 meshes iron powder is pressed by isostatic pressing and baked by high temperature to be formed into the pipe wall of the utility model; the wall thickness of the pipe wall is 0.5 to 40 millimetres and the diameter of the pipe wall is 4 centimeters to 8 inches. The utility model has the advantages of simple structure, good pressure resisting feature and convenient installation, and the oil-sad separation effect is better than that of the filter pipe winded by stainless steel wire.
Description
The utility model relates to oil field oil recovery machiner equipment, a kind of specifically improvement of oil-sand separator tube.
In the oil producing operation of oilfield exploitation, be used for the oil-sand separator of well oil layer section, normally adopt outer wall to twine the filter pipe of stainless steel wire, crude oil is to filter by the slit.The shortcoming that it brings is: the slit is easily stifled, and the steel wire rapid wear that is twined can only disposablely use, the cost height.
The purpose of this utility model provides a kind of long service life, is difficult for stopping up slit, the oil-sand separator tube that cost is low.
Technical essential of the present utility model is:
Tube wall adopts 10 orders-700 purpose iron powder through waiting static pressure compacting, high temperature sintering moulding, and wall thickness is the 0.5-40 millimeter, diameter be 4 minutes-8 cun.
Advantages such as oil-sand separating effect of the present utility model surpasses the filter pipe that stainless steel wire twines, and it has simple in structure, and compressive property is good, and is easy for installation.Use it not to be prone to clogging, can carry out pulse cleaning, repeatedly use continuously.
Accompanying drawing is a structural representation of the present utility model.
1 is iron powder in the wall among the figure, and D is a diameter, and b is a wall thickness.
Length of the present utility model is to decide as required, and sintering temperature is 800 ℃-1300 ℃.Adopt cold isostatic press compression moulding (pressure is at 2600Kg-4000Kg), make through high temperature sintering, the micropore size of microfiltration tube is several microns to hundreds of microns.It is mounted in the external diameter of stay pipe, and crude oil enters in the pipe by this poromerics.
Claims (1)
1, seamless micropore filter oil sand separation pipe is characterized in that tube wall adopts 10 orders-700 purpose iron powder through waiting static pressure compacting, high temperature sintering moulding, and wall thickness is the 0.5-40 millimeter, diameter be 4 minutes-8 cun.
