Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] Attached below Figure 1-4 and specific embodiments to further describe the application principle of the present invention.

[0055] An automatic anti-collision drilling system, the automatic anti-collision drilling system uses the following methods to achieve anti-collision:

[0056] Step 1. Establishing a three-dimensional drilling graphic entity model library by using a three-dimensional animation modeling method;

[0057] Step 2, input the track data of the old well and the new well, generate a triangulation digital surface model, and combine the triangulation digital surface model with the track dat...

Abstract

The invention discloses an automatic anti-collision drilling system which comprises a vibration sensor module, a data acquisition analyzer module, a drill bit control module and a data signal transmitter module. The data acquisition analyzer module is connected with the vibration sensor module, the data signal transmitter module is connected with the data acquisition analyzer module and the drill bit control module, and the drill bit control module is arranged on a drill bit and used for controlling the advancing direction of the drill bit. By the aid of the automatic anti-collision drilling system, high-grade, precision and advanced devices are omitted, implementation of other drilling processes cannot be affected, actions of the drill bit can be accurately, rapidly and directly controlled on the premise of insusceptible measurement while drilling, so that anti-collision operations for an adjacent well are rapidly and timely responded to and adjusted, and safety of drilling operations is improved.

Description

technical field [0001] The invention belongs to the technical field of drilling platform management, in particular to an automatic anti-collision drilling system. Background technique [0002] At present, the number of offshore large cluster wells and infill adjustment wells drilled in old land well areas has shown a significant increase. The problem of collision becomes increasingly prominent. Wellbore collisions lead to scrapped footage and repeated construction, and the simultaneous abandonment of two wells affected the progress of construction and increased costs. With the increasing demand for oilfield development, the number of drilling wells in many oilfields has shown a trend of substantial growth. Therefore, many oil fields, especially oil fields with a well pattern area, are facing a greater risk of wellbore collision. During the drilling process, if the drill bit is not found in time to be close to the casing of the adjacent well, an accident of collision betwe...
