Description
Technical field
The utility model relates to a kind of drilling tool.
Background technology
Need drill earth's crust surface in order to obtain crude oil, natural gas, water, steam or other similar substances.The typical method of probing is that the drilling rod of connecting band threaded tubular becomes so-called drill string, and drill string is pierced the stratum.
Each root tube drilling rod all has threaded thick section at the joint of its end.The purpose of the joint of these thickenings is in order to guarantee that when whole drill string hangs on offshore boring island jackrod structure is enough to bear the weight of below drill string and is not destroyed.Simultaneously, the existence of the joint of thickening also can prevent to be placed under the open hole environment when drilling rod, and produces with the open hole wall in drilling process that the drilling rod wall is worn through when contacting.
In drilling process, drilling rod is contacting with the open hole borehole wall of high wear, and the drilling rod wall can attenuate, if excessive wear may cause the drill string fracture, even the drill string well accident that falls takes place.
Because the buried depth of natural resource becomes more and more darker; and often in the horizontal direction away from offshore boring island; drill string length is more and more longer; especially at oil and gas industry; for how protecting tool joint in the drill string, there have been a plurality of solutions to be suggested in the past to guarantee the structural integrity of drill string.This area is known, can improve this because the integrality defective of the drill string self that fault in material causes by increase parts or appendage to drilling rod.In decades, wherein a kind of to improve method be the wear-resisting band of surface soldered one deck (Hard Banding) in the drill pipe thickening section.This wear-resisting band is made up of multiple carbon tungsten compound or other similar carbide alloy.The making of this wear-resisting band will separated drill string operation field and carry out to special machining location usually, and needs the expensive technician and the input of equipment, and cost is very high.Because in all drilling engineerings, drill string is the maximum equipment of fund input, and the interruption that the drill string scene of separating will be caused drilling process is till wear-resisting band completes and transports drilling rod back operation field.The probing industry is all wished and can be worked continuously, and works continuously if keep, and again drill string is separated the wear-resisting band of field fabrication, just must two overlaps drill strings, and only this just doubles the investment of drill string.If in the drilling at the sea operation, also need to bear the high expense and the loss of time that whole drill string is shipped off to processing servicing center on the bank.
It is worn out that the another one defective of only using the scheme of wear-resisting band is that the hard carbon tungsten compound that constitutes wear-resisting band is enough to the sleeve pipe that will contact with borehole wall stratum in drilling operation course, especially in drilling well by the easier generation of regional this phenomenon that vertically transfers level to.So-called sleeve pipe is a kind of bigger pipe of being laid in the well, and fixes with concrete when drilling well arrives certain degree of depth.In most of the cases, along with the increase of drilling depth, the descending sleeve pipe of size can be placed along the degree of depth successively.When lay at one section sleeve pipe of a certain degree of depth finish after, can adopt one more the drill string of minor diameter in the sleeve pipe of concrete permanent fixation, carry out creeping into of next round.Therefore, though in the application of boring peupendicular hole, wear-resisting band is considered to that in this area the wearing and tearing that reduce drill string are had important effect, but wear-resisting band also can cause serious destruction to sleeve pipe, especially in drilling well by the zone that vertically transfers level to, often cause the destructive inefficacy abandoned well of having to owing to being worn through by the sleeve pipe of permanent fixation.
Also there are a lot of problems at the regional drilling rod of so-called cutting bed and the wearing and tearing of sleeve pipe.So-called cutting bed is meant drilling well by the zone that vertically transfers level to, and in this section zone, sleeve pipe may be laid, and also may not lay.Landwaste is at this area deposition and be not easy to be taken to the well face by drilling fluid.Because the weight of drilling rod self, in drilling process, drilling rod crouches on rubble and rotation, if rubble or landwaste by loosening and shift the well face onto, will the aggravating of the wearing and tearing of drilling rod and sleeve pipe.Rubble and landwaste gather the equivalent circulating density (ECD) that also is enough to improve drilling fluid, thereby influence normal operation process.
That describes before us is this wear-resistant, and the material of reduction torsion and pulling force can be guaranteed the safety of drill string and keep its structural integrity, and this material checks before maintenance and/or the replacing there is certain friction durability at needs.At present mode of occupation in the art is to need the number of the drilling rod arranged and corresponding safety inspection information still by the paper and pen record on any drill string, and an every increase and a drilling rod that is arranged in drilling well all are recorded on the form of being made by offshore boring island.The method of this record or tracking can be counted the total length that the drilling rod that has used in any drillng operation, but can not be very detailed distinguish the number of times that a certain drilling rod is used, can not get rid of the potential mistake in the existing record system.
