三、Fishing tools★
1、Taper Tap
The taper tap is a special fishing tool making thread in tube dropped object such as drill pipe and oil tube.The taps
are turned from high trength alloy steel forging materials and heat treated.It is made with chip groove so as to make
threads.The box tap is a special external fishing tool which is engaged on the outside wall of tubing objects such as
oil tubing and drill pipe.

3、CLF Type Fishing Magnet 反循环强磁打捞器
The CLF type fishing magnet in petroleum and geology exploration is used for fishing of small fallen objects in the
down hole.With some of advantages such as simply structure,easy to operate, reliable performance, small size and
lightweight,it is equipped with permanent magnet iron which can attract small objects such as teeth wheel, palm,
tong teeth and tool so that small objects in down hole are fished and the well bottom is cleaned up.

6、The LL Type Reverse Circulation Junk Basket
The LL type reverse circulation junk basket is used to retrieve all types of small junk objects such as
cone,cutter,hand tool and junks from the bottom hole.During drilling operation,it produces a local reverse
circulation of fluid at well core so as to effect a complete recovery of junk in the junk basket .Especially when PDC
bit is used ,cleaning bottom well by the tool becmes very necessary to ensure the bit with a normal application.The
reverse circulation junk basket therefore becomes an essential tool in oil ,geology exploration and drilling
engineering.
