1. Introductio      

   At present, torepair oil and gas wells under high pressure, the method is use workover rig,snubbing device, trailer, crane, generators and other equipment work togetherto solve the problems. This method need much more auxiliary equipment and couldcost much time during installation.

   LHM9401TBJ truck mounted snubbing unit. Oursnubbing unit combined and integrated workover rig, snubbing devices, BOP, andspecial adjustable rack base on a truck’s chassis.

2. Advantages and Parameters

(1) It is ahighly integrated system installed in a semitrailer for easy transporting,vertical adjusting and wellhead docking. It moves quickly and installedefficiently between wellheads and flange. Saving a lot of time and cost.

(2) It docks towellhead rapidly with six degrees of freedom such as up & down, left &right, forward & backward.

(3) It allowsoperating with high pressure in oil and gas wells. The max static sealingpressure is 70 MPa. The max dynamic sealing pressure is 35 MPa.

(4) It is highlyintegrated without hydraulic hoses dismantle connection and carry between powerunit and BOP unit.

(5) It is aclean process by highly sealed operation.

3.Main parts of LHM9401TBJ truck mountedsnubbing unit

LHM9401TBJ iscomposed of two parts, the power device and wellhead device . the power deviceis skid mounted structure (20* standard cargo), to provide hydraulic power tothe wellhead device and BOP; the wellhead device is integral structure.

Power devicemainly including hydraulic power system, liquid control system, electric systemand other accessories.

Wellhead installations include BOP, balanced relief systems, slipsystems, lifting systems, self elevating masts, operating consoles, platformsand other accessories.
