| A method and apparatus for penetrating a well casing (12) and surrounding earth strata includes the insertion of a flexible shaft (24) having a ball cutter (22) on an end thereof into upset tubing (18) within a well casing. The upset tubing is provided with an elbow (20) at its lower extremity for receiving the ball cutter therein. The flexible shaft is then rotated and the ball cutter cuts a hole in the well casing and is then moved horizontally a distance, usually less than 12 inches (30.5 cm). The flexible shaft and ball cutter are then removed and a flexible tube (48) having a nozzle blaster (46) on an end thereof is then inserted into the upset tubing in the channel. A fluid of surfactant and water at high pressure is then pumped into the tube wherein the high pressure fluid passes through orifice in the spiral drill thereby cutting an extension into the previously cut channel. The tube is continually fed into the channel as the high pressure fluid continues to blast away the earth's strata. The channel is then cut a preselected distance from the well up to 200 feet (61 meters) and beyond. | ||||||
| 215 | Joint assembly | EP97305115.4 | 1997-07-10 | EP0853202A1 | 1998-07-15 | Vukovic, Ivan |
A joint assembly is disclosed for connecting two spaced drive shafts (36, 38), such as in a submergible pumping system. The joint assembly comprises a connecting shaft (34) having enlarged bodies (40) on each end thereof, a housing (44) surrounding each enlarged body, each housing connectable to one of the drive shafts, lock devices (46, 48) for preventing relative rotational movement of the connecting shaft (34) with respect to the drive shafts (36, 38), and mechanisms (56,60,66; 56,60,64) within each housing acting upon the enlarged bodies (40) to bias the connecting shaft into coaxial alignment with the drive shafts. With this joint assembly lateral displacement or "wobble" of the drive shafts (36, 38) is permitted, yet the bias mechanisms (56,60,66; 56,60,64) tend to restore the drive shafts to coaxial alignment. |
