The specific embodiment

With reference to accompanying drawing, the utility model is further described.The modular rig mainly comprises fixedly 6 big modules such as shared module 7 of rig primary module 1, circulation module 2, control module 3, cementing equipment module 4, well cementing material module 5, power plant module 6, ground, also has rack for rods 8 in addition, sleeve pipe conveying device 9, and the track 10 that supplies rig primary module 1, circulation module 2, control module 3 to move.Rig primary module 1 moves on track 10, and sleeve pipe conveying device 9, rack for rods 8 are outside track, and rig primary module 1 is fixed with the position of sleeve pipe conveying device 9, rack for rods 8 during rig work.

Rig primary module 1 can be the new exclusive rig, also can form, mainly comprise the control system of overhead traveling crane, derrick, base, winch, suspension system, manifold, wellhead assembly, rotating disk, manifold and water, gas, liquid, electricity standard drill transformation.

The function of circulation module 2 is the needs that satisfy in the drilling process drilling fluid, with the drill fluid purification equipment configurations on transportable module.The landwaste of circulation module 2 can be transported to control module 3 through conveyer, realizes recovery, the processing of drilling cuttings, avoids contaminated environment.Circulation module 2 mainly comprises drilling fluid tank, vibrosieve, desilter, desander, associating cleaner, centrifuge, agitator, borehole pump, suction tank, landwaste conveying device etc.

Control module 3 major functions are to carry out the electric power control of relevant device on the rig primary module 1, realize the taking back and process of landwaste, landwaste are transported to the processing place of appointment by vehicle.The power source of control module 3 provides electrical power to rig primary module 1 and other equipments in power plant module 6 after control module 3.Control module 3 comprises that mainly Electric Machine Control room, well site (MCC), silicon controlled rectifier room (SCR), head pusher room, data are handled room, vertical centrifuge, landwaste conveyer, puddled jar, ash can, vibrosieve (landwaste handle with), supercentrifuge (sewerage treatment with), sewage-treatment plant etc. down.

Rig primary module 1, circulation module 2, control module 3 are sequentially arranged on the track 10, and move along track 10.Rig primary module 1, circulation module 2, control module 3 can connect earlier, in track 10 upper edge tracks 10 same moved further; Also can be separately independent, move successively at track 10 upper edge tracks 10, and after the position of rig primary module 1 is determined, again that rig primary module 1, circulation module 2, control module 3 is fixedly connected.
