Abstract

The apparatus has at least two pumps (9, 10) which are arranged above one another in the well filter (21), interconnected and can be shut off from one another by an intermediate piece (12) with armature (11), and which in each case are accommodated in a housing consisting of a closed extension piece (1, 2; 26, 6) and a perforated suction piece (3, 4), the suction pieces (3, 4) being sealed in relation to the well filter (21) and connected to injection pipes (13, 25). An extension piece (1, 2) is surrounded by a long sleeve (28) which is fastened to it and can be pressed against the well filter (21) and which seals the well filter (21) on the inside. During operation of the lower pump (10) and with the upper pump (9) at a standstill, compressed air, aggressive or inert gas together with water is injected into a section of the filter gravel pack. Subsequently, with switching in of the upper pump (9), a rinsing and desanding phase takes place. <IMAGE>
