A separator (7) and method for separating fine and coarse particles that are carried by a production fluid during production of a well to reduce downtime and pump wear. The finer fraction is withdrawn with the produced fluid to the surface while the coarse particle fraction falls by gravity to the base of the well. Production fluid is forced through a conical shaped annulus in a separator (7). The inner conical surface of the annulus includes a radial slot through which the produced fluid is drawn laterally and then upwardly along with the finer particles. The width of the conical-shaped annulus can be adjusted by changing the relative axial position of conical-shaped valve members (16, 17) by a threaded connection (12) between base member (14) and pipe (10). The width of the radial slot between the separator members (16, 17) can also be adjusted by a threaded connection between rod (18) and spider (13). |
