Description

Electric well drilling machine without drilling rod

Technical field

The utility model relates to a kind of drilling rod transmission that need not, and provides energy by cable for the shaft bottom motor, is directly driven the electric well drilling machine without drilling rod of drill bit drilling well by motor.

Background technology

In existing trepan, no matter be the trepan that utilizes impact principle, still utilize the trepan of rotation principle, it all is to transmit energy and drive drill bit by drilling rod to carry out drillng operation.When boring deep-well, as in petroleum exploration and development, just need huge rig, tall and big derrick, many drilling rods that needs transfer torque, the heavy work when even tearing drilling rod open etc.

Summary of the invention:

In order to overcome existing many deficiencies of being with the trepan of drilling rod, the utility model provides a kind of electric well drilling machine without drilling rod, the motor portion in shaft bottom given the electric power transfer of ground power supply with cable by this trepan, motor portion drives drill bit and implements drill-well operation in the shaft bottom, and bottom equipment and pipeline come ascending, descending by wirerope and winch.

The technical scheme that its technical problem that solves the utility model adopts is: in the housing of drill bit rear end motor portion is set; Motor portion drives the drill bit that is connected with housing front end axle; Shell end is provided with pipeline inlet port and screw, and screw helps the mud that makes in the borehole wall to return ground; Housing outer surface is provided with the support bar that creeps into that can adjust collapsing length, and creeps into support force and regulates drilling direction for drill bit provides; Power supply and ground controller are connected with motor portion and aspect sensor in the housing by power supply and control spool, pipeline inlet port, thereby electric energy are provided and control the collapsing length adjustment drilling direction that respectively creeps into support bar for motor portion; Slush pump is by the space of defeated mud tube, pipeline inlet port and drill bit central authorities, for drilling well provides mud; Winch is connected with the pipeline inlet port by wirerope; Power supply and control spool, defeated mud tube are fixed on the wirerope equipment and the ascending, descending of pipeline steel cable in the borehole wall by clamp.

The beneficial effects of the utility model are, compare with existing trepan, and it can save a large amount of drilling rods that need transfer torques, need not tall and big derrick, the company of need not, tear this heavy work of drilling rod open.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a schematic diagram of the present utility model

Among the figure: 1, winch; 2, power supply and ground controller; 3, slush pump; 4, wirerope; 5, power supply and control spool; 6, defeated mud tube; 7, clamp; 8, pipeline inlet port; 9, screw; 10, drill bit; 11, creep into support bar; 12, aspect sensor; 13, housing; 14, motor portion; 15, the borehole wall.

The specific embodiment

In Fig. 1, in the housing (13) of drill bit (10) rear end motor portion (14) is set; Motor portion (14) drives the drill bit (10) that is connected with housing (13) front end axle; Housing (13) end is provided with pipeline inlet port (8) and screw (9); Housing (13) external surface be provided with can adjust collapsing length creep into support bar (11); Power supply and ground controller (2) are connected with motor portion (14) and aspect sensor (12) in the housing (13) by power supply and control spool (5), pipeline inlet port (8), for motor portion (14) electric energy is provided and control respectively creep into support bar (11) thus collapsing length adjustment drilling direction; Slush pump (3) is by the space of defeated mud tube (6), pipeline inlet port (8) and drill bit central authorities, for drilling well provides mud; Winch (1) is connected with pipeline inlet port (8) by wirerope (4); Power supply and control spool (5), defeated mud tube (6) are fixed on the wirerope (4) by clamp (7); In drilling process, aspect sensor (12) feeds back to power supply and ground controller (2) with the parameters such as orientation of drill bit (10) and housing (13) at any time; Power supply and ground controller (2) control motor portion (14) drives drill bit (10) and creeps into; Regulate the collapsing length that each creeps into support bar (11), for creeping into the power of providing support and regulating drilling direction; Drive screw (9) rotation, help things such as making the interior mud of the borehole wall (15) and institute's landwaste of taking thereof to return ground; When need retract well head with drill bit (10) etc., winch (1) retracts wirerope (4) and drill bit (10) etc. is retracted, screw (9) reverse rotation is that the lifting of drill bit equipment such as (10) provides service hoisting power and the effect of removing obstacles, and power supply that is fixed together by clamp (7) and wirerope (4) and control spool (5) and defeated mud tube (6) also are thus lifted to well head immediately.

Claims

1, a kind of electric well drilling machine without drilling rod, in the housing (13) of drill bit (10) rear end motor portion (14) is set, motor portion (14) drives the drill bit (10) is connected with housing (13) front end axle, it is characterized in that: power supply and ground controller (2) are connected by power supply and the pipeline inlet port (8) of controlling spool (5), housing (13) rear end and housing (10) interior motor portion (14) and aspect sensor (12); Slush pump (3) is by the space input drilling mud of defeated mud tube (6), pipeline inlet port (8), the interior mud channel of housing (13) and drill bit (10) central authorities; Winch (1) is connected with pipeline inlet port (8) by wirerope (4); Motor portion (14) connects and adjusts the collapsing length that each creeps into support bar (11); Housing (13) is terminal to serve as that the screw (9) that axially is provided with is subjected to being in transmission connection of motor portion (14) with pipeline inlet port (8).
