Abstract
The invention provides a downhole tool used for righting and centralizing a geological resource exploration drilling tool and capable of preventing the drilling tool and a sleeve from abrasion. The downhole tool can realize righting and centralizing of the drilling tool, can prevent the drilling tool and the sleeve from abrasion, and comprises an abrasion-proof downhole tool body (1) and an abrasion-resistant ring (2) made of a polyurethane material; lug bosses made of the polyurethane material and used for playing a supporting and righting role are arranged outside the main component of the abrasion-resistant ring (2) made of the polyurethane material, and a plurality of lubricating grooves are formed in parts, in contact with the abrasion-proof downhole tool body (1), inside the abrasion-resistant ring; the abrasion-resistant ring (2) made of the polyurethane material is inlaid on the abrasion-proof downhole tool body (1), and can be clamped tightly to avoid sliding of the abrasion-resistant ring (2) up and down through a lower drill rod coupling (6) and the abrasion-proof downhole tool body (1). During drilling, the drilling tool can be in local contact with the sleeve (7) through the abrasion-resistant ring lug bosses (3) made of the polyurethane material to rotate in the sleeve of the abrasion-resistant ring (2), so that effects of supporting the sleeve and centralizing the drilling tool are realized; characteristics of high elasticity and good abrasion resistance of the polyurethane material are adopted, so that a problem of the abrasion between the drilling tool and the sleeve is solved.
Description
Technical field
The present invention relates to a kind of geological resource exploration drilling drilling tool placed in the middle and casing wear prevention downhole tool, the especially equipment to drilling well drilling bar righting placed in the middle, drilling rod and casing wear prevention.
Background technology
At present, in the drilling process such as geological drilling stratum resource, drilling tool and drilling rod creep into predetermined well section at barefoot interval and stratum friction, after Open-Hole Section mounting sleeve, drilling tool and drilling rod with regard to all in sleeve pipe rotation transmit torsion and carry out darker bore hole to drill bit and creep into, there is drilling tool and drilling rod external surface and the mutual wear problem of internal surface of casing, not only cause attenuate to affect Service Life of Casing on casing wear, also make the wearing and tearing such as drilling tool and drill pipe coupling more serious, need to change or repair, increase drilling tool maintenance cost.Drilling tool in drilling process and drilling rod and sleeve pipe and stratum wearing and tearing are problems that can not be ignored.
Summary of the invention
The invention reside in and solve the wear problem existing in above-mentioned drilling well drilling process, a kind of drilling tool and casing wear prevention downhole tool are provided, can not only make drilling tool righting rotate between two parties reduce the amplitude of oscillation steadily creep into, and can avoid drilling tool and sleeve pipe, drilling tool and stratum directly wear and tear drag reduction lower consumption object.
The technical solution adopted for the present invention to solve the technical problems is: on drilling tool and drilling rod tubing string, be installed in series and be connected several drilling tools and casing wear prevention downhole tool body (1) short circuit with the corresponding site of downhole drill instrument and drilling rod according to need protection well section, on abrasionproof downhole tool body (1), be inlaid with polyurethane material wear ring (2), the thickening outer rim ring item boss of the T-shaped button drill pipe coupling of portion (6) and abrasionproof downhole tool body (1) blocks polyurethane material wear ring (2) on the lower, compression prevents from sliding up and down, can only rotate, between two jointed rods, just increase like this polyurethane material wear ring boss (3) that one diameter is greater than drill pipe coupling external profile diameter, in the time that drilling tool creeps into, drilling rod utilizes polyurethane material wear ring boss (3) local contact sleeve pipe (7), the polyurethane material wear ring boss (3) connecting between drill pipe coupling just can make drilling rod placed in the middle, play support centralizing function, drilling tool rotates in polyurethane material wear ring (2), utilize polyurethane material wear ring boss (3) and sleeve pipe (7) or stratum friction, avoid the direct contact wear in drilling tool and sleeve pipe or drilling tool and stratum.Cylinder and the same footpath of drill pipe coupling outer rim between main member polyurethane material wear ring boss (3), be convenient to the circulation of Drilling Water mud pit shaft, polyurethane material wear ring (2) inwall is provided with lubrication groove (4), and drilling tool reaches the object of righting casing wear prevention reduction placed in the middle frictional resistance by abrasionproof downhole tool body (1) and polyurethane material wear ring (2) relative motion.
The invention has the beneficial effects as follows; can be between drilling tool and drilling rod; be installed in series and be connected several drilling tools and casing wear prevention downhole tool body (1) with the corresponding site of downhole drill instrument and drilling rod according to need protection well section; to ensure the not directly contact of drilling tool and sleeve pipe or stratum; make the placed in the middle and casing wear prevention of well drilling tool righting, avoid the loss of drilling rod and sleeve pipe or stratum wearing and tearing, raising Service Life of Casing; reduce drilling tool maintenance cost, save drilling engineering expense.
