Description
Technical field
The present invention relates to the placed in the middle and casing wear prevention downhole tool of a kind of geological resource exploration drilling drilling tool, especially to the equipment of 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 rub at barefoot interval and stratum and creep into predetermined well section, after Open-Hole Section mounting sleeve, drilling tool and drilling rod transmit torsion and carry out darker bore hole to drill bit with regard to all rotating in sleeve pipe and creep into, there is drilling tool and drilling rod external surface and the mutual wear problem of internal surface of casing, not only casing wear is caused and thinningly affect Service Life of Casing, drilling tool and drill pipe coupling etc. is also made to wear and tear more serious, need to change or repair, increase drilling tool maintenance cost.Wearing and tearing in drilling tool in drilling process and drilling rod and sleeve pipe and stratum is a problem that can not be ignored.
Summary of the invention
The invention reside in the wear problem solving and exist in above-mentioned drilling well drilling process, a kind of drilling tool and casing wear prevention downhole tool are provided, drilling tool righting can not only be made to rotate between two parties reduce the amplitude of oscillation steadily to creep into, and drilling tool and sleeve pipe, drilling tool and stratum can be avoided directly to wear and tear object that drag reduction lowers consumption.
The technical solution adopted for the present invention to solve the technical problems is: on drilling tool and drilling rod tubing string, several drilling tools and casing wear prevention downhole tool body (1) short circuit is connected according to the corresponding site of well section and downhole well tool and drilling rod need be protected to be installed in series, abrasionproof downhole tool body (1) is inlaid with polyurethane material wear ring (2), polyurethane material wear ring (2) blocks by the thickening outer rim ring item boss of the T-shaped button drill pipe coupling (6) in portion and abrasionproof downhole tool body (1) on the lower, compression prevents from sliding up and down, can only rotate, between two jointed rods, just increase by one diameter is greater than the polyurethane material wear ring boss (3) of drill pipe coupling external profile diameter like this, when drilling tool creeps into, drilling rod utilizes polyurethane material wear ring boss (3) localized contact sleeve pipe (7), the polyurethane material wear ring boss (3) connected 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), polyurethane material wear ring boss (3) is utilized to rub with sleeve pipe (7) or stratum, avoid drilling tool and sleeve pipe or the direct contact wear of 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 by abrasionproof downhole tool body (1) and polyurethane material wear ring (2) relative motion the object that righting casing wear prevention placed in the middle reduces frictional resistance.
The invention has the beneficial effects as follows; can between drilling tool and drilling rod; several drilling tools and casing wear prevention downhole tool body (1) is connected according to the corresponding site of well section and downhole well tool and drilling rod need be protected to be installed in series; to ensure that drilling tool and sleeve pipe or stratum directly do not contact; make the placed in the middle and casing wear prevention of well drilling tool righting, avoid the loss that drilling rod and sleeve pipe or stratum wear and tear, raising Service Life of Casing; reduce drilling tool maintenance cost, save drilling engineering expense.

Detailed description of the invention
Be described with reference to the accompanying drawings:
As shown in Figure 1, by drilling rod and drilling tool and casing wear prevention downhole tool body (1) short circuit order of connection cased well section schematic diagram.Be drill pipe coupling (6) below, abrasionproof downhole tool body (1) short circuit, be that drill pipe coupling (5) installed in series in order is on drilling tool tubing string above, abrasionproof downhole tool body (1) is inlaid with polyurethane material wear ring (2), polyurethane material wear ring (2) blocks by the thickening outer rim hoop boss of the T-shaped button drill pipe coupling (6) in portion and abrasionproof downhole tool body (1) on the lower, compression prevents from sliding up and down, can only rotate, when drilling tool creeps into, drilling rod rotates the amplitude of oscillation and utilizes polyurethane material wear ring boss (3) localized contact sleeve pipe (7) in sleeve pipe, play the effect of supporting sleeve righting drilling tool, avoid drilling rod and casing wear.
As shown in Figure 2, abrasionproof downhole tool body (1) top is T-shaped drilling tool box, it is T-shaped drilling tool pin thread that thickening outer rim clamps bushing polyurethane material wear ring (2) bottom, when creeping into, drilling tool and abrasionproof downhole tool body (1) rotate in sleeve pipe, and abrasionproof downhole tool body (1) has contacted the effect of friction, lubrication drag reduction with polyurethane material wear ring (2) relative motion.
On the wear ring of polyurethane material shown in Fig. 3 (2), outside longitudinally uniform polyurethane material wear ring boss (3) outward flange that is arranged with is greater than drilling tool coupling external profile diameter, rises and supports centralizing function; Between polyurethane material wear ring boss (3) hoop, cylinder and abrasionproof downhole tool body (1) box cupling thicken the same footpath of outer rim, are convenient to drilling circulation cement paste and pass through.
Shown in Fig. 4, polyurethane material wear ring (2) is top view.
On the wear ring of polyurethane material shown in Fig. 5 (2), its inner loop is to being provided with twice lubricating groove (4), its effect is that drilling tool and abrasionproof downhole tool body (1) rotate in sleeve pipe when creeping into, and abrasionproof downhole tool body (1) has contacted the effect of friction, lubrication drag reduction with polyurethane material wear ring (2) relative motion.
In drilling process, as adopted without box cupling drilling rod, being laid down by upper for a set of abrasionproof downhole tool body (1) bushing polyurethane material wear ring (2) is installed in series with another set of complete abrasionproof downhole tool body (1) short circuit is connected, utilize two covers to thicken outer rim hoop boss clamping polyurethane material wear ring (2), reach righting and abrasionproof effect.Effectively prevent drilling tool to change the line of production the raw damage caused that rubs in sleeve pipe inward turning, can drag reduction consumption reduction, improve drilling efficiency and extend Service Life of Casing.
