Description
Technical field
The present invention relates to a kind of oil drilling and extracting equipment, particularly a kind of electric connector for continuous-tube downhole electric instrument.
Background technology
development along with the continuous-tube correlation technique, continuous-tube and relevant device thereof more and more have been applied in horizontal well, in the drilling well of directional well and well logging, because continuous-tube is one section continuous thin-wall circular tube, conventional drilling rod compares, in operation process, do not need jointing, formed the continuous passage of a connection ground installation and downhole tool pipe nipple, therefore, build down-hole power and signalling channel by penetrate cable in continuous-tube, carry out the motor-driven drilling well logging and carry out motor-driven drilling than under conventional drilling rod and log well to have higher feasibility and better advantage.So, can utilize down-hole power and the signalling channel set up, give the power supply of downhole tool pipe nipple, and transmit control signal and receive metrical information, because downhole tool pipe nipple type is various, its function is had nothing in common with each other and (is for example measured drilling tool hole deviation and orientation, measure strata pressure, measure the pressure of the drill, measure temperature etc.), therefore be difficult to all transducers are integrated in a downhole tool pipe nipple.When some underground work, will carry out the connection of the different downhole tool pipe nipple of two functions, connection for the downhole tool pipe nipple, complete two functions, one is the connection on mechanical structure, and one is that power is connected connection with signalling channel, usually, connection on mechanical structure is all that the API drilling rod button by standard is realized, such as NC50 etc.
In prior art generally the electric connector of the connector form by the routine power that carries out the downhole tool pipe nipple be connected connection with signalling channel, but twist for fear of marking of cables when connecting, can increase the difficulty of execute-in-place and the complexity of downhole tool pipe nipple mechanical structure; For example open mobilizable side window on downhole tool pipe nipple outer wall, during connection, drilling rod button between first connecting short section, again hand is put in the side window on outer wall, complete the connection of inner plug-in type electric connector, clearly, the side window mode has increased the fussy degree of execute-in-place, has also affected to a certain extent the intensity of the pipe nipple of windowing.in addition, can also carry out by non-rotating joint the connection of downhole tool pipe nipple, non-rotating joint generally is comprised of a male joint and a female joint, male joint and female joint are connected on different downhole tool pipe nipples, at this moment, first connect inner plug-in type electric connector, again the male joint of non-rotating joint is connected with female joint, its connected mode is similar to union and connects, and compares the union connected mode, has increased on its structure and has prevented that pin and box sub from counterrotating structure occurring, compare the side form of windowing, the use of non-rotating joint, although avoided the weakening to pipe nipple outer wall intensity, but do not reduce the fussy degree of execute-in-place, also brought simultaneously new problem, because needs reserve the manual operation space for inner plug-in type electric connector, just the plug side cable of electric connector need to be reserved one section, its length should be greater than operating space along the axial length of pipe nipple, obviously, this mode is connected with female joint after connection completing non-rotating joint male joint, can be with cable disc in non-rotating joint, especially when cable size is larger (such as including forceful electric power power core), will affect the drilling liquid flow circulation passage.
Summary of the invention
The object of the invention is to overcome in prior art the different downhole tool pipe nipples of two functions by patch form connect more complicated, operation is more difficult, and by non-rotating joint, connect and cable disc need to be not suitable with in joint the above-mentioned deficiency that the larger cable of diameter connects, a kind of electric connector is provided, this electric connector can be more quickly and easily carries out connection between the downhole tool pipe nipple at operation field, in the drilling rod button of connecting downhole instrument pipe nipple, complete the connection of electric connector signalling channel.
