Description
Technical field
This product belongs to drilling technology field, is specifically related to a kind of drill pipe filter.
Background technology
In drilling process, for filtering mud impurity, preventing downhole instrument or bit port blocking, using cleaner more.Existing drill pipe filter mostly is tapered integral structure, and this structure not only transports inconvenience, and processing difficulties, costly.Overall with regard to loss of function after part erosion damages, the part of damage can not be changed, cause cleaner entirety to be scrapped.
Summary of the invention
The purpose of this utility model there is the high advantage of transport inconvenience, processing difficulties and replacement cost to solve existing drill pipe filter, and provide a kind of Telescopic drill rod cleaner.
This Telescopic drill rod cleaner comprises the first filtration joint, and the first threaded upper ends filtering joint is connected with retainer ring, and the inside thread of retainer ring is connected with the overcurrent lid with annular flowing hole, and the center of overcurrent lid is fixed with bailing handle; Also comprise the second filtration joint and the 3rd and filter joint, the first lower end of filtering joint is provided with interior shoulder, and the second upper end of filtering joint is provided with outer shoulder, and second filters joint filters joint first lower end by shoulder anatomical connectivity; Second lower end of filtering joint is provided with interior shoulder, and the 3rd upper end of filtering joint is provided with outer shoulder, and the 3rd filters joint filters joint second lower end by shoulder anatomical connectivity; 3rd bottom of filtering joint is enclosed construction.
The utility model has following beneficial effect:
This Telescopic drill rod cleaner, for being installed in the drilling rod box under kelly saver sub, can playing and filter drilling fluid impurity, prevents the effect of downhole instrument or bit port blocking.The telescopic structure design of three sections of filter joints, makes it easy to carry, simultaneously this split-type design, can realize the independent replacing of each joint, greatly save cost; Each joint filters joint and all adopts cylinder design, and the processing of this shape is simple.The utility model structure is simple, esy to use, safe and reliable, and each joint all can be changed separately, meets onsite application requirement; In drilling process, have and filter mud by discharge orifice, ensure that in drilling process, bit port does not block, and makes shaft bottom circulate unobstructed, for modern drilling technology provides a kind of novel, cost-effective technological means.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-the first filters joint; 2-overcurrent lid; 3-flowing hole; 4-bailing handle; 5-the second filters joint; 6-the three filters joint.
Detailed description of the invention
Below in conjunction with Fig. 1, the utility model is described further:
The threaded upper ends that this Telescopic drill rod cleaner comprises the first filtration joint 1, first filtration joint 1 is connected with retainer ring 2, and the inside thread of retainer ring 2 is connected with the overcurrent lid 3 with annular flowing hole, and the annular channel of overcurrent lid 3 is for the drilling fluid that circulates; The center of overcurrent lid 3 is fixed with bailing handle 4; during use, retainer ring 2 is sitting in the drilling rod box under kelly saver sub; be processed with shoulder inside it, the outer shoulder filtering joint 1 with first matches, and filtering joint 1 to first plays axial limiting effect jointly with overcurrent lid 3.The lower end also comprising the second filtration joint 5 and the 3rd filtration joint 6, first filtration joint 1 is provided with interior shoulder, and the second upper end of filtering joint 5 is provided with outer shoulder, and second filters joint 5 by the lower end of shoulder anatomical connectivity at the first filtration joint 1; Second lower end of filtering joint 5 is provided with interior shoulder, and the 3rd upper end of filtering joint 6 is provided with outer shoulder, and the 3rd filters joint 6 filters joint 5 second lower end by shoulder anatomical connectivity; 3rd bottom of filtering joint 6 is enclosed construction.Three filtration joint Surface Machining have multiple external diameter to be less than the filter bores of 8mm, and each joint external diameter that filters reduces successively, and entirety becomes tapered structure, and this design can filter joint number amount according to actual conditions adjustment.This Telescopic drill rod cleaner, for being installed in the drilling rod box under kelly saver sub, can playing and filter drilling fluid impurity, prevents the effect of downhole instrument or bit port blocking.The telescopic structure design of three sections of filter joints, makes it easy to carry, simultaneously this split-type design, can realize the independent replacing of each joint, greatly save cost; Each joint filters joint and all adopts cylinder design, and the processing of this shape is simple.The utility model structure is simple, esy to use, safe and reliable, and each joint all can be changed separately, meets onsite application requirement; In drilling process, have and filter mud by discharge orifice, ensure that in drilling process, bit port does not block, and makes shaft bottom circulate unobstructed, for modern drilling technology provides a kind of novel, cost-effective technological means.
