发明名称 Downhole apparatus
摘要 Apparatus for perforating a section of liner intersecting a hydrocarbon-bearing formation comprises a length of tubing, the wall of the tubing defining a plurality of apertures, and perforating charges being located in the apertures. The tubing is adapted for mounting on the lower end of a length of production or test tubing such that the formation fluid may flow into the tubing and then directly into the production or test tubing. The charges disintegrate on detonation to leave the apertures unobstructed and to form light or small parts which may be swept out of the well by the formation fluid. Following detonation of the charges, the flow area of the tubing corresponds to the tubing internal diameter.
