Description
Technical field
The utility model relates to the special fishing device of a kind of oil gas field air hammer drill bit, particularly relates to the special fishing socket of a kind of oil gas field air hammer drill bit.
Background technology
Gas drilling is that the circulatory mediator being continuous phase by the gas such as air, nitrogen injects pit shaft, to realize the drilling mode for the purpose of clean well.Because air drilling has remarkable result in raising rate of penetration, improvement severe well leakage, protection reservoir etc.In recent years, air drilling at home multiple oil field and block has carried out extensive utilization, creep into owing to have employed the diverse brand-new hammer drilling bit with conventional roller bits working method, it creeps into the several times that rate of penetration can reach conventional drilling, but along with a large amount of utilizations of air hammer, underground air hammer bore bit case accident happens occasionally.In China Patent No. " 96226845.3 ", disclose a kind of fisher salvaging the overall bore bit of down-the-hole drill, publication date is 1998-02-04, and this technology is not also suitable for the special salvaging of oil gas field air hammer drill bit.
The domestic Special fishing tool that there is no process air hammer drill bit and come off at present, once run into air hammer drill bit case accident in During Air Drilling, under the condition of existing fishing tool, make the extremely difficult and poor efficiency of salvaging process, have impact on drilling efficiency greatly, adding drilling cost simultaneously, therefore in the urgent need to inventing the special box tap of a kind of oil gas field air hammer drill bit, solving the problem.
Summary of the invention
The purpose of this utility model is the problems referred to above overcoming prior art existence, provides a kind of oil gas field air hammer drill bit special fishing socket.The utility model can realize fast and accurately salvaging underground air hammer bore bit spline following junk, improves gas drilling accident treatment efficiency, meets efficient, rapid drilling requirement.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The special fishing socket of a kind of oil gas field air hammer drill bit, it is characterized in that: comprise length adjustment pipe nipple, salvage cylindrical shell and tool joint, described length adjustment pipe nipple lower end is connected with salvaging cylindrical shell, upper end is connected with tool joint, salvage on cylindrical shell lower surface and be provided with mill teeth, salvage on cylindrical shell and offer circulation port, salvage on cylinder inboard wall and be provided with salvaging screw thread, salvage screw thread between mill teeth and circulation port, salvage screw thread and mate with needing the anti-lost screw thread of air hammer drill bit salvaged.
Described salvaging cylindrical shell lower surface is slit into zigzag and forms mill teeth.
Described circulation port quantity is three, is distributed on and salvages on cylindrical shell.
Described length adjustment pipe nipple lower end is connected with salvaging cylindrical shell by screw thread, and upper end is connected with tool joint by screw thread.
Employing the utility model has the advantage of:
One, to have structure simple for the utility model, fishing success ratio is high, the feature such as easy and simple to handle, air hammer drill bit junk that is irregular, different size can be salvaged from outside, also reusable after salvaging, and security reliability is high, the aspects such as raising gas drilling accident treatment efficiency, fishing success ratio are played a significant role.
Two, the utility model can realize fast and accurately salvaging underground air hammer bore bit spline following junk, improves gas drilling accident treatment efficiency, meets efficient, rapid drilling requirement.
Three, in the utility model, described salvaging cylindrical shell lower surface is slit into zigzag and forms mill teeth, when there being talus deposit, by the rotation of mill teeth, can clear up discharge to annular space landwaste, is convenient to salvage cylindrical shell and is lowered into position.
Four, in the utility model, described length adjustment pipe nipple lower end is connected with salvaging cylindrical shell by screw thread, and upper end is connected with tool joint by screw thread, by the adjustable salvaging length of length adjustment pipe nipple, salvages wider.
