The column drilling process comprises the following steps: as shown in fig. 3 and 6-8, a power drill rod box 1 lifts and inclines a single upright post storage frame 1 of 2 columns in the box, the upright posts roll into a pipe rack 10 of a power cat 2, a hydraulic cylinder outside the pipe rack 10 extends to generate an inclination angle, a pipe column is loaded into a power catwalk 2 through a loading plate 9, the power catwalk 2 is lifted to the height of a drill floor, a pulley 8 pushes the upright posts to the center direction of a well mouth until a joint of the upright posts is completely exposed out of the power catwalk 2 for a certain length, a drilling machine traveling crane system starts to be lifted after a power elevator 7 buckles the upright posts, and when the upright posts are about to leave a drill post feeding device of the power catwalk 2, a buffer manipulator 3 swings out to push the upright posts to the center of the well; the drilling machine traveling crane system lowers the column, a male joint at the lower end of the column is inserted into a tubular column string female joint in the well, an iron roughneck 4 butts the lower end of the column with the tubular column string female joint in the well, then the iron roughneck 4 retracts to the initial position, the top drive connects the upper end of the column with a top drive central tube together, the top drive continues drilling after the completion, after 1 column is drilled, the drilling machine traveling crane system lifts the tubular column string in the well to be higher than the drilling platform surface by about 1.2m, a power slip 6 clamps the tubular column string in the well, and after the tubular column string in the well and the top drive connecting joint are disassembled by the top drive, the next column is connected and.

The drill-out/drill-throwing process comprises the following steps:

step 1, lowering a drilling machine traveling and hanging system, buckling a well inner upright column string by a power elevator 7, loosening a power slip 6 when the drilling machine traveling and hanging system is lifted up until the lowest end of the 1 st upright column is 1.2m higher than a drilling platform surface, clamping the well inner upright column string by the power slip 6, extending an iron roughneck 4 out to be disconnected from the lower end of the upright column and be connected with the well inner upright column string, retracting the iron roughneck 4 to an initial position, buckling the pipe column string by a slurry blowout prevention box 5, slightly lifting the drilling machine traveling and hanging system, and completely lifting the lower end of the upright column from a female buckle of the well inner upright column string by the drilling machine traveling and hanging;

step 2, the buffer manipulator 3 extends out of the standby position to the center of a wellhead to push the lower end of the upright to the power catwalk drill string feeding device, the upright slides downwards along the power catwalk drill string feeding device along with the lowering of the travelling crane system until the lower end of the upright is placed on the pulley 8, the power elevator 7 opens the buckled upright, and the pulley 8 pulls the upright to move until the upright reaches a horizontal state;

step 3, as shown in fig. 4-5, a kicking-out mechanism 11 of the power catwalk 2 kicks the stand column from the catwalk to a pipe rack 10, the power drill rod box 1 inclines at a certain angle, the pipe rack 10 rolls the stand column into the end of the pipe rack 10 through inclination, a loading arm 12 of the power drill rod box 1 loads the stand column to the power drill rod box 1 tightly attached to the catwalk, and the power drill rod box 1 can roll the stand column to another power drill rod box 1 tightly attached to the catwalk through inclination;

and 4, repeating the process until the drill pulling/throwing is completed.

The invention saves the work of frequently building roots and throwing single roots for the drilling machine with short drilling period and frequent transition, greatly shortens the drilling period, improves the drilling efficiency and reduces the labor intensity of workers. The two-layer platform mechanical arm, the power two-layer platform, the drill floor mechanical arm, the rat hole and the stand platform required by the traditional tubular column automatic processing system are not configured, the stand column is not stored in the drill floor, the weight of a drilling machine base and a derrick can be greatly reduced, the space of the drill floor is increased, the visual field is good, and the economic benefit is considerable.

The drilling machine is not provided with a racking platform, a vertical root platform and a rat hole, and the automatic tubular column processing system is not provided with a racking platform manipulator, a power racking platform, a drilling platform manipulator and a rat hole. Whole well drilling, play the underrun, get rid of and bore mainly use 2 single 1 stands as the owner, and 2 single 1 stands are directly carried to the well head from power drill pipe box with the underrun in-process to creep into, get rid of and bore 2 single 1 stands and directly carry to power drill pipe box from the well head in the journey.

2, the single upright column 1 is firstly built in advance in a well site or a factory and is stored in a power drill pipe box, and the well drilling at other well positions does not need to build the upright column, and the built upright column is directly used. The power catwalk has the function of discharging and conveying 2 single vertical columns 1 or single vertical columns. The power drill rod box and the power catwalk adopt a pulling type structure, so that the power drill rod box and the power catwalk can be conveniently and quickly transferred.

The difference between the automatic processing flow of the pipe column in the drilling process and the automatic processing flow of the pipe column in the drilling process is that the upper end of the upright post in the drilling process does not need to be connected with a top drive central pipe, and other processing flows are completely the same.
