ABSTRACT:
The filter of the present invention overcomes the aforementioned problems by separating gas and solid particulate matter from liquid as the wellbore fluid passes through the filter. The apparatus comprises a solid tube encased in a perforated tube which extends beyond the end of the solid tube. A top cap is attached to one end of each tube and holds the tubes concentric to each other. A bottom cap is attached to the end of the perforated tube which extends beyond the solid tube. An annulus is defined by the inner surface of the perforated tube and the outer surface of the solid tube. The top cap has a bore extending therethrough which is in fluid communication with the solid tube. The filter is generally used in conjunction with a low volume pump located adjacent to and in fluid communication with the top cap. As the pump operates, wellbore fluid is drawn through the perforations of the perforated tube into the annulus between the perforated and solid tubes. Although fluid flow is turbulent outside the filter, fluid flow in the annulus stabilizes, allowing gas, liquid, and solids to separate based on their individual densities. The effect of this separation is that the gas, which is less dense than the liquid, bubbles up through the liquid and forms a distinct layer above the liquid layer. The solids, conversely, settle to the bottom of the liquid layer. The solid tube extends down beyond the gas layer into the liquid layer. Since the pump is in fluid communication with the solid tube, the liquid layer becomes the only layer from which the pump draws fluid. The result is that only liquid, substantially free of gas, is introduced into the pump. Additionally, wire cloth can be used to pre-strain the fluid before it enters the annulus, removing solid particulate matter and larger gas bubbles.
