Description
Technical field:
The utility model relates to a kind of down-hole mechanical parameter measurement instrument that is used for the directional well drilling construction.
Background technology:
In the directional well drilling work progress, need accurately to grasp down-hole mechanical parameters such as drill bit the pressure of the drill, torque-on-bit, drill string vibration, hydrophthalmia and annular space mud pressure.Yet; at various directional wells extended reach well particularly; in the wellbore construction of special track well such as horizontal well; the part drilling tool often accumbency or horizontally-inclined on the borehole wall; make the drilling tool and the borehole wall produce very big frictional resistance; ground is consumed by frictional resistance in the face of the pressure of the drill and the moment of torsion part that drill bit applies; therefore; true pressure and moment of torsion that drill pressure that ground shows and torque-on-bit are not on the downhole drill bit to be applied; drill free or drill bit overvoltage appear in regular meeting under the situation of complex formation; this brings many uncertain factors for the directional well wellbore construction; influence rate of penetration; prolong drilling period; mule foot a bit appears when serious easily; accidents such as lost cone influence normally carrying out of wellbore construction.
Summary of the invention:
The purpose of this utility model be to provide a kind of can the directional well drilling construction in particular cases accurately record down-hole mechanical parameters such as the pressure of the drill, moment of torsion, thereby guarantee the directional well drilling down-hole mechanical parameter measurement instrument that wellbore construction normally carries out.
The utility model is to realize like this.This kind measuring instrument comprises transition pipe nipple assembly and measure portion, the transition pipe nipple assembly is by transition pipe nipple, axially link closely barrel, long-neck tube, semicircle locating ring, transitional cylinder formed, and measure portion is by last pipe nipple, inner core, inner core positioning bolt, tight fixed bolt, hollow bolt, hydrophthalmia mud pressure sensor, annular space mud pressure sensor, printed circuit board (PCB), urceolus, interlayer barrel, drill pressure sensor, pipe nipple, urceolus fastening bolt, torque-on-bit sensor and " O " shape sealing ring are formed down.Last pipe nipple and inner core are connected and fixed by positioning bolt; The hydrophthalmia pressure sensor is contained on the inner core, and the annular pressure sensor is contained on the pipe nipple, and drill pressure sensor and torque-on-bit sensor are contained in the pipe nipple lower end, and closely contacts with following pipe nipple upper end convex head; In the open slot in the inner core outside printed circuit board (PCB) is housed, vibrating sensor is housed on it; Following pipe nipple is connected and fixed by urceolus fastening bolt and urceolus, and be articulated on the pipe nipple by the interlayer barrel, during normal drilling well, drill pressure and moment of torsion pass on bit weight sensor and the torque sensor by following pipe nipple, stress deformation by sensor, make the bridge circuit foil gauge output signal of telecommunication that is attached on the sensor, thereby measure the pressure of the drill and moment of torsion.In like manner, hydrophthalmia pressure and annular pressure are also measured the signal of telecommunication by corresponding pressure sensor, and the vibrating sensor on printed circuit then can be measured drill vibration frequency and amplitude parameter.
The utility model is novel, and is reasonable in design, utilizes it can be under the specific condition of directed drilling construction, accurately record down-hole mechanical parameters such as the pressure of the drill, moment of torsion, help improving rate of penetration, reduce drilling parameter, shorten the wellbore construction cycle, be suitable for and apply.
