Abstract
The utility model discloses a drill water-hole clip which has a filter screen for the drilling in the petroleum industry, which is a special apparatus for preventing the blockage of the drill water-hole. The utility model comprises a clip and the clip is arranged with the filter screen which is connected with the clip by a spring plate. The utility model can not only fix the water-hole of the drill but also keep the sand out of the water-hole. The utility model does not hinder the pass of the drilling mud and has the filtration function. The utility model solves the problem of the intake of the sand in the drill water-hole, which radically solves the problem that the sand blocks the drill water-hole in the process of the getting down of the drilling tool. Therefore the utilization of the utility model can avoid the related accident and the repeated pipe trip and at the same time can avoid the waste of the mud, which is beneficial to the environmental protection and convenient for the operation of the drilling workers. .
Description
Technical field
This use is novel when relating under the oil drilling drilling tool operation, prevents the special implement that bit port stops up, and particularly with the bit port clamp of filter screen, uses on drill bit.
Background technology
Drill bit is the essential instrument that drilling well is used, and for the circulation of high pressure drilling liquid, drill main body is provided with the water hole, and the hydrophthalmia of carbide alloy is installed in the water hole, by the hydrophthalmia clamp hydrophthalmia in the water hole is fixed.Being drilled to a bite well often needs to change a plurality of drill bits, and in brill, reaming were constructed down, the phenomenon that the grains of sand on the borehole wall stop up bit port often took place.Bit port is blocked after death, causes drilling tool drilling fluid behind the shaft bottom to circulate, and also just can't implement next step the operation of creeping into.Forced have to pull out of hole, bore down again, not only workload is very big, and whole post mud is sprayed onto ground and is difficult to reclaim, and promptly causes a large amount of wastes of man-hour and material, pollutes the well site environment again.If down-hole situation complexity, hole quality is poor, and also can causing pulls out of hole pulls out serious accidents such as piston, well slough, bit freezing.Yet in drilling well tripping operation process, if there is not concrete measure, sand enters and stops up hydrophthalmia in the drilling tool is inevitably, never has good solution for many years.
Summary of the invention
The purpose of this utility model just is to provide the bit port clamp of band filter screen, solves the drill bit water blockoff eye problem that exists in the wellbore construction for many years, reduces the drilling failure rate, reduces production costs.
Use the present technique solution can reach above-mentioned purpose: the bit port clamp of band filter screen comprises clamp, filter screen is set in clamp is connected by latch plate.
Use the utlity model has following useful effect: the utility model adds a filter screen on former clamp, and hydrophthalmia that can fixed drill bit can be blocked in sand outside the hydrophthalmia again, and passing through of not overslaugh drilling mud plays a role in filtering.Under when boring midway under turn on pump or the drill bit behind the shaft bottom circulating mud, under the effect of water-horse power, the screen pack by latch plate connects is easy to be opened, and does not influence normally and creeps into.The utility model has solved the problem of sand water inlet eye, and the problem of the stifled bit port of sand in the drilling tool process has been avoided drilling failure that is therefore caused and the problem that repeats to make a trip under fundamentally solving.Simultaneously, also avoid the waste of mud, protected environment to make things convenient for driller's operation, reduced cost of production.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: the bit port clamp of band filter screen, comprise clamp 1, filter screen 2 is set in clamp 1 connects by latch plate 4.The size of the mesh 3 on the filter screen 2 can be made into different models according to the size of bit port.The utility model is installed in below the bit port, with G.I.H of drill bit.When tripping operation, the mud in the down-hole annular can enter in the drilling tool, and the sand in the annular space then is blocked in the outside by filter screen 2, prevents that sand from entering drilling tool, is deposited on below the drilling tool, blocks hydrophthalmia during turn on pump.Midway under turn on pump or the drilling tool behind the shaft bottom circulation time, under the effect of water-horse power, the filter screen 2 that connects by latch plate 4, be easy to be opened, the normal circulation of influence is not crept into, along with the passing of drilling time, filter screen 2 is slowly stung by high-pressure slurry, together returns on the ground with landwaste.Bit change more at every turn, the hydrophthalmia clamp that all more renews guarantees that the drilling well fault of water blockoff eye does not appear in each tripping operation, avoids the drilling failure that causes thus.
