API LT Type Overshot for Downhole Drilling Tubing Fishing Tool

タイトルまたは説明

LT overshot is one of the fishing tools which is fishing the pipes externally. It can catch drill collar, drill pipe, tubing, subs and other pipes. Because of the seals, the fluid can circulate with the high pump pressure after catching the fish. The top of the fish will be milled by under mill shoe. The releasing and circulating overshot can also work with jars to catch the stuck fishes. If the catched fish cant be release from stucking ,we could release the overshot and lifting the drill string. Overshot consists of three outside parts: top sub, bowl, and standard guide. The basic overshot may be dressed with either of two sets of internal parts, if the fish diameter is near the maximum catch of the overshot, a spiral grapple, spiral grapple control, and type A packer are used. If the fish diameter is considerably below maximum catch size (½ or more) a basket grapple and a mill control packer are used.
