Description

Oil tank mechanism of guide drilling thrust device

Technical Field

The utility model relates to a drilling equipment technical field, in particular to direction drilling thrust device's oil tank mechanism.

Background

Along with the continuous deepening of oil and gas exploration, complex ultra-deep directional wells and large-displacement horizontal wells are increasing. In the drilling construction of a large-displacement horizontal well, along with the lengthening of a horizontal section, the supporting pressure and the abrasion resistance of a downhole drilling tool are larger and larger, the track control difficulty is large, the mechanical drilling speed is slow, and the conventional drilling technology cannot meet the construction requirement easily.

In order to solve the above problems, the applicant conducted extensive manual work and developed a pilot drilling apparatus capable of controlling a string of vertical drilling apparatuses to drill along a prescribed trajectory.

The steerable drilling apparatus includes three independently controlled lateral thrusters, each thrust piston of which exerts a controllable thrust on the rib. Therefore, when the three wing ribs are opened and pushed against the well wall, three component forces are generated in different three directions, and the three component forces are finally gathered into a resultant force acting on the well wall and form an acting angle with the well wall. Conversely, after the well track is set, the magnitude and the direction (angle) of the pushing force of the upper wing rib of the guiding instrument acting on the well wall can be adjusted through software control, so that the drilling tool drills along the specified track, and the drilling track is accurately controlled.

The prior art lacks an oil tank mechanism suitable for driving the thrust device piston to move.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

The technical solution of the present invention is further explained with reference to fig. 1 and fig. 2.

The utility model provides a direction drilling thrust device's oil tank mechanism, including oil pipe 1, oil bag 2, oil bag connecting rod 5, oil tank skeleton 4, oil bag presses seat 6 and oil tank socket 3, oil

bag connecting rod

5 and 4 fixed connection of oil tank skeleton, oil pipe 1 cup joints on oil

bag connecting rod

5, 2 covers of oil bag are established in the 1 outside of oil pipe and are cup jointed on oil tank skeleton 4, oil tank skeleton 4's outside fixed connection oil

bag presses seat

6, 2 crimping of oil bag press in oil tank skeleton 4 and oil bag press between seat 6, oil tank socket 3 presses seat 6 fixed connection with oil bag.

The outer side walls of the oil bag pressing seat 6 and the oil tank socket 3 are provided with a plurality of annular grooves, and O-shaped rings 7 are arranged in the annular grooves.
