Detailed Description
The following describes embodiments of the present invention with reference to the accompanying drawings.
Referring to fig. 1-7, a cable suspension downhole device comprises a steel cable 1, wherein two ends of the steel cable 1 respectively bypass two bearing circular steel pipes 2 and are manually pulled at the ends of the steel cable; the middle part of steel cable 1 sinks to the inside of pore-forming 7 to support at its middle part and be used for the pit shaft 6 of well formation, the bottom of pit shaft 6 is provided with well support 3, and the bottom central point that holds in the palm 3 at the well puts to be processed and is used for with 1 matched with well support recess 4 of steel cable, the top of pit shaft 6 is provided with and is used for two adjacent 6 butt joints of pit shaft to accept insert ring 5, accept and insert ring 5 and set up the 8 cartridge cooperations in the slot of well support 3 bottoms. Through the device of going into well of suspension cable of above-mentioned structure, in the use, when needs are transferred pit shaft 6, at first support the location on steel cable 1 with first section pit shaft 6, and guarantee well support recess 4 and 1 cooperation location of steel cable, again with 1 both ends winding bearing circular steel pipe 2 of steel cable and taut, the artifical same speed pine steel cable 1 of both sides, 6 downhole conveyances that will form pit shaft, sink to the drill way position when 6 wellheads of upper segment pit shaft, with the taut hover of steel cable 1, lay lower section pit shaft 6 behind the upper segment pit shaft, both ends are simultaneously with the speed pine steel cable 1, after the well becomes, take out steel cable 1 from one end can.
Furthermore, two ends of the steel cable 1 are wound on the two bearing circular steel pipes 2 for 1-2 circles respectively and are tensioned. The friction force between the steel cable 1 and the bearing circular steel pipe 2 can be increased by winding for 1-2 circles, and the normal issuing process of the steel cable is further ensured.
Further, the width of the well support groove 4 is larger than the diameter of the steel cable 1. Can lead and spacing through foretell well support recess 4 to steel cable 1, guarantee that it can be in transferring the in-process, carry out effectual support to its pit shaft 6.
