API 7-1 Oilfield Drilling Downhole Tool Junk Sub
Product Overview
Due to the fact that the O.D. of external bowl of fishing cup is bigger and a smaller circular space is available between external bowl of fishing cup and well hole; the mandrel diameter at cup mouth is larger so that it has a bigger annular space, therefore, the fluid at the cup mouth form a swirls and suddenly fall down so as to reduce the carrying capacity. By this way, some heavy objects will drop in cup and be fished out so that the purpose of cleaning ofhole toe is carried out.
During drilling process, LB type Junk Sub is applied mainly for fishing of shivers and fallen objects such as carbide tooth, drill bit and bearing which can’t be carried out of hole by conventional fluid circulation etc. It possesses important functions to keep hole toe cleaning, increase bit service life, reduce and prevent drill bit from unexpected damage. The tools are available with all sizes and super performance.
