Reverse Circulating Junk Basket
Reverse Circulating Junk Basket Type LL is used to retrieve small-sized fishes, such as cone, cutter, hand tools and junks from the hole. The drilling mud can produce reverse circulation locally at the bottom of a well; therefore the fishing is easy. Moreover, it can be used as a special coring tool.
OD Range: 3-3/4�� ~20��
Max. OD of fish: 2-3/8�� ~18-1/4��
Connection: API
Junk Sub
Junk Sub Type LB is a practical and effective tool. During drilling operation, it can be used to recover the heavier drilling cuttings or metal chips which are difficult to be lifted out of the borehole by normal drilling fluid circulation.
Suitable Well Diameter: 4-1/4�� ~18��
OD Range: 3-3/4�� ~13-3/8��
ID Range: 25/32�� ~ 4��
Connection: API
Overall length: 19-1/2�� ~ 40��
Grapple Releasing Spear
Grapple Releasing Spear Type LM is a simply constructed and high strength fishing tool by which fishing job is performed through the interior bore of the fish. It is mainly used to recover the lost drill string, tubing and casing, and can also be used in conjunction with internal cutter, bumper jars, etc. to finish cutting and recovering at the same time.
ID of Fish: 1-19/32�� ~ 12-3/4��
Diameter of Guide cone: 1-29/64��~8-1/4��
Tensile Load (Lbf): 44,960 ~1,654,670
Tool joint connection: API
Overshot Type
Overshot Type LT-T is an effective tool used for catching the fish with smooth external surface. Its circulation can be carried out under high pump pressure and the fish can be released on the inside of well. According to different uses, it may be equipped with some accessories, such as extension sub, wall hook, enlarged guide, etc.
OD Range: 3-1/2�� ~13-3/8��
Tool joint connection: API
Max. Catch Size (Spiral): 2-3/8�� ~11��
Max. Catch Size (Basket): 1-7/8�� ~9��
Fishing Multifunction
Fishing Multifunction Type DLQ is a new and ideal fishing tool for cleaning the bottom of well. It integrates the functions of fishing cup, fishing magnet and claw fishing basket into an organic whole. Therefore, it can be used for fishing fallen substances of metal particles or for clawing the large-sized gear wheel and tong�s tooth.
