Abstract
The invention discloses a fishing needle, a fishing device and a fishing method for fishing a soft material in a tube for an oil gas well. The fishing needle comprises a fishing rod (2); at least one fishing pin (3) is arranged on the peripheral surface of the lower section of the fishing rod; and an included angle alpha formed between the axes of the fishing pin and the fishing rod in the upward direction is an acute angle. The fishing device comprises the fishing needle, a hoisting mechanism and a steel wire rope, wherein the upper end of the fishing rod is connected with the hoisting mechanism by the steel wire rope. The fishing method comprises the following steps that: 1, the fishing needle is placed into an orifice of the tube for the oil gas well, the fishing needle is lowered down and the depth of the falling material is determined; and 2, the steel wire rope is recovered by 5 to 8m, then the hoisting mechanism is controlled to rapidly lower down the steel wire rope, the fishing rod and the fishing pin of the fishing needle pierce into the falling material, an inverted hook is formed after the fishing pin pierces into the falling material and the hoisting mechanism hoists the steel wire rope to lift the fishing needle and the falling material to the orifice so as to take out of the falling material. The invention can solve the problem that the soft irregular material falls into the tube after the well is drilled and in the testing operation and is difficult to take out.
