Embodiment 1

[0010]An intelligent drilling method includes the following steps:

[0011]S1, design well structure: Φ444.5mm drill bit*1115m+311.2*3225m+215.9*5900m, the first step is to select a 444.5mm drill bit through the robot arm and sensor and put it into the bit box. The design of the first drill bit assembly is: Drill bit + double female + 9" drill collar, the actual mechanical arm grabs a column of 9" drill collar through the sensor and puts it on the top drive elevator, the elevator is closed, the mechanical arm is released, the top drive is lifted to the predetermined position, and the mechanical arm grasps again Double female to the buckle device on the drill floor, lower the drill collar to buckle, the iron driller moves to the drill tool position and buckles to the best torque, and the iron driller leaves to the original position. The double female and the drill bit are engaged, the iron driller moves to the position of the drill tool to buckle to the best torque, and the iron driller...

Abstract

The invention discloses an intelligent well drilling method. The method comprises the following steps: S1, designing a well bore structure: phi 444.5 mm drill bit*1115m+311.2*3225m+215.9*5900m; and S2, according to the data designed in the step S1, after materials are prepared, automatically operating the drilling technological process till well completion. Only one person is needed to input programs and maintain, efficiency is high, labor force is saved, the automation degree is high, off-line operation or remote control can be achieved, no person is needed, the personnel skill requirement ishigh, the personnel number requirement is small, and alarm processing is conducted in time when parameters are abnormal.

Description

Technical field[0001]The invention relates to the field of shale gas exploration and development, in particular to an intelligent drilling method.Background technique[0002]The current traditional oil drilling technology is based on design and arranges operators to complete each process step by step manually. On the one hand, there will be a series of discontinuities in the operation of personnel, such as errors, fatigue, and the link between each step, and the drilling time efficiency is very low. , Restricting the efficiency of oil and gas extraction, on the other hand, there are hidden safety hazards, which may occur.Summary of the invention[0003]In view of the above-mentioned drawbacks, the present invention provides an intelligent drilling method, which only requires one person to input the program and maintenance, is efficient and saves labor, has a high degree of automation, can be operated offline or remotely controlled, no one is safe, and requires high skills. , The number ...
