Abstract
An integrated well construction system (IWCS) operable for constructing a well via integrated control of integrated control devices that collectively control integrated subsystems of the IWCS. The IWCS includes an IWCS communication network, the integrated control devices (each directly connected with the IWCS communication network), the integrated subsystems, and a control workstation (450, 452, 454) directly connected with the IWCS communication network and operable to control each of the integrated control devices to thereby control the integrated subsystems.
Claims24
An apparatus comprising:
- a control workstation for use with an integrated well construction system (IWCS), wherein the IWCS is operable for constructing a well via integrated control of a plurality of integrated control devices that collectively control a plurality of integrated subsystems of the IWCS, and wherein the control workstation comprises:
- a human-machine interface (HMI) comprising a display, a touchscreen, a joystick, and a processing system comprising a processor and a memory having a construction program thereon that, when executed by the processor:
- presents a human operator of the control workstation with a setup wizard guiding the operator through entering operating parameters for one or more well construction machines of the integrated subsystems to perform a well construction sequence;
- and
- controls the integrated control devices, and thus the integrated subsystems, to perform the well construction sequence based on the entered operating parameters.
An apparatus comprising:
- an integrated well construction system (IWCS) operable for constructing a well via integrated control of a plurality of integrated control devices that collectively control a plurality of integrated subsystems of the IWCS, wherein the IWCS comprises a processing system comprising a processor and a memory having a construction program thereon that, when executed by the processor:
- controls each integrated control device, and thus each integrated subsystem, during each of a plurality of predetermined operational sequences;
- and
- prevents collisions between machines of the IWCS.
A method comprising:
- constructing a well utilizing each of a plurality of automatically controlled well construction machines, including:
- a drawworks;
- an iron roughneck;
- a tong-handling trolley;
- a tong-handling arm;
- a catwalk;
- a tubular delivery arm;
- a lower stabilizing arm;
- an upper tubular restraint;
- an intermediate tubular restraint;
- a lower tubular restraint;
- a top drive;
- a top drive elevator;
- a fingerboard;
- a transfer bridge racker;
- a setback guide arm;
- a mousehole;
- a mousehole;
- a drilling fluid pumping system;
- and
- a drilling fluid recondition system.
A system operable to completely control each of a plurality of predetermined operational sequences of a well construction operation, wherein the sequences include:
- picking up single tubulars;
- making drilling connections;
- building tubular stands;
- tripping-in drill collar stands;
- tripping-out drill collar stands;
- tripping-out wet;
- backreaming;
- moving single tubulars from a well center to a catwalk using a top drive;
- moving tubular stands from the well center to the catwalk;
- moving casing from the catwalk to the well center using a casing tong;
- moving casing from the catwalk to the well center using a tubular delivery arm and a casing running tool;
- moving large diameter casing from the catwalk to the well center using the top drive and the casing running tool;
- building casing stands;
- and
- tripping-in casing stands without using the casing running tool.
