Description:
Overshot is a downhole tool used in fishing operations to engage on the outside surface of a tube or tool. A grapple, or similar slip mechanism, on the overshot grips the fish, allowing application of tensile force and jarring action. If the fish cannot be removed, a release system within the Overshot allows the overshot to be disengaged and retrieved.

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 canâ??t 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 â??Aâ?? packer are used. If the fish diameter is considerably below maximum catch size (�½â?? or more) a basket grapple and a mill control packer are used.
Riding on unfathomable volumes of industrial expertise, we are engaged in exporting a wide range of releasing and circulating overshot in beijing, china. Releasing and circulating overshot is special external fishing tool used for fishing drill collar, dill pipe, tubing and other fished in drilling and work over operation.According to different uses, it may be equipped with some accessories, such as extension sub, wall hook, oversize guide, etc.

General instruction: We offer a complete line of single & double and triple tube core barrels, which willl provide superior performance and obtain the full recovery of the sample in any application of diamond core drilling. Using a wireline system, core is recovered quickly by retrieving the inner tube directly through the drill string. The rods remin in the hole until the bit needs to be replaced. This has big cost advantages when drilling deep holes for mineral exploration. The core barrel assembly is composed of the inner-tube group and outer-tube group. Advantages: 1.Faster coring at greater depths 2.Good stability due to constant diameter of the drill string 3.Excellent hydraulics 4.Good core recovery
