Description
Technical field
This utility model relates to a kind of petroleum exploration logging device, particularly to a kind of oil well logging coring device.
Background technology
Well logging is to obtain various petroleum geologies and the effective way of engineering data, and the exploitation for oil gas field has great importance.Coring well logging can understand fabric in more detail, it is possible to is carried by bottom material to bottom surface and carries out detailed analysis.Tradition coring device is only capable of realizing the vertical coring in shaft bottom, it is impossible to realizes the coring of borehole wall side, is difficult to carry out for developing side-wall coring.This utility model devises a kind of oil well logging coring device, utilizes hydraulic cylinder and turbine rotor to realize borehole wall side coring, has higher practical value.
Summary of the invention
The purpose of this utility model is aiming at the deficiency that prior art exists, it is provided that a kind of oil well logging coring device, utilizes hydraulic cylinder and turbine rotor to realize borehole wall side coring, has higher practical value.
A kind of oil well logging coring device, it is characterized in that: include motor, reciprocating pump, drilling fluid pot, the borehole wall, pump case, hydraulic cylinder, piston rod, turbine stator, turbine rotor, bevel gear first, bevel gear second, corer, pressure valve and coiled tubing, described motor is connected with reciprocating pump, described reciprocating pump entrance is connected with drilling fluid pot, the outlet of described reciprocating pump communicates with coiled tubing endoporus, in bottom described coiled tubing, hole exits communicates with pump case, described pump case sidewall is provided with hydraulic cylinder, piston rod is arranged in hydraulic cylinder by piston, piston rod end is provided with round end, it is provided with turbine stator bottom described pump case, turbine rotor it is provided with below turbine stator, described bevel gear first is arranged on turbine rotor, described bevel gear first coordinates with the bevel gear second being arranged on corer, it is provided with pressure valve bottom described pump case.
Driven by motor reciprocating pump, reciprocating pump sucks mud from drilling fluid pot and injects pump case by coiled tubing, and high-pressure slurry enters hydraulic cylinder, promotes piston rod to stretch out to the left；High-pressure slurry becomes high velocity mud, high velocity mud impulse turbine rotor, turbine rotor high-speed rotation by turbine stator, and turbine rotor is slowed down by bevel gear first and the engagement of bevel gear second and driven corer to rotate；Under the thrust of piston rod, corer rotates into borehole wall side, completes coring.
