Wellbore filter screen and related methods of use

A wellbore tool for filtering debris from a well fluid and adapted to be lowered into a wellbore on a tubing string, the tool comprising:

• a first elongated tool housing having a first interior passageway for flow of well fluids through the first housing, the first housing having a first inlet and a first outlet, the first housing adapted for connection in a tubing string;
• a porous deflection cone positioned in the first housing for preventing a portion of debris from passing through the first elongated housing;
• a first inner tube in fluid communication with the first inlet, the first inner tube positioned within the first housing and defining a first annulus between the first inner tube and the first housing for capturing the portion of debris prevented from passing through the first housing;
• a second elongated tool housing having a second interior passageway for flow of well fluids through the second housing, the second housing having a second inlet that is in communication with the first outlet and a second outlet, the second housing adapted for connection in the tubing string;
• an elongated screen member positioned in the second housing, defining a first second annulus between the second housing and the screen member;
• and
• a second inner tube in fluid communication with the second housing inlet, the second inner tube positioned within the screen member and defining a third annulus between the second inner tube and the screen member, one end of the second inner tube in fluid communication with the second housing inlet, the second inner tube for directing fluid flow from the second housing inlet into the second annulus, the third annulus for capturing debris from the fluid.
