At present, the field of domestic oil and gas pipelines

Most big bore The longest distance

Mountain directional crossing

Successful pullback of XCMG horizontal directional drilling rig

Pair Rich Design Technology、Accumulating experience is of great significance.

The other day，XugongXZ6600 Super Large Tonnage Horizontal Directional Drilling Machine，Appeared in Hekou, Xigu District, Gansu Province，Facing the Directional Crossing Project of Natural Gas Connection Pipeline，Achieve a complete success of one-time towback。The crossing length of the project is 1492.m，The specification of the main pipeline isΦ914×23.6mm，The specification of the optical cable tube isD114*6.0mm，The lithology is mudstone（Contains about 200mLong joint），YesAt present, the most big bore in the field of oil and gas pipelines in China.、Longest distance mountain directional crossing project。

Due to the deep buried depth of the project pipeline，The mountain is undulating，The drilling point is limited by the site condition，Primary assembly welding is not available、Tow back condition，Adopted by the project party“Nine after one”Pullback scheme，XugongXZ6600 Horizontal Directional DrillIt took 10 days to pull back successfully.，Refresh the domestic big bore.、A New Record of Directional Drilling in Long Distance Mountain。

XugongXZThe 6600 Horizontal Directional Drilling Rig is built by XCMG to meet customer needs.，Independently developed large-tonnage horizontal directional drilling rig。Its rotation speed is fast.、The torque is large、The pushing and pulling force is large、The push-pull speed is high，Maximum pullback force up to 6600kN, Maximum giant slalom torque 210000. N·m，Suitable for large aperture、Long distance working condition crossing。

During construction，XugongXZ6600 horizontal directional drilling rigDigital display system，Rotational Torque、Direct display of main construction parameters such as push and pull force。 Dual engine power systemCombined with proprietary multi-condition speed regulation technology、Rotation、Push-pull multi-gear control technology，So that the drilling rig is not only powerful、The formation adaptability is strong and the fuel consumption is saved.，30% less fuel than conventional rigs％Above。Clamping vice with three cylinders，Reliable clamping of drill rod，The shackle torque is large，Wherein the vice can float all the way，Convenient casing method construction technology。

On the degree of intelligence，XCMG horizontal directional drilling rigRemote Internet of Things system，The owner can know the construction progress and other information in real time.。Cloud data processing platform and“Drill into the clouds”Internet of ThingsAPPComplement each other，Yeah, pull、Torque and other drilling rig operation data to achieve full process monitoring、Remote upload。XCMG senior technical team conducts real-time data analysis in the cloud，Achieve support and guarantee，Provide professional technical guidance and complete solutions for construction customers。

XugongXZ6600 is a veteran in the Trenchless field.，Excellent performance in all major projects, has completed the Dongxing branch line of Zhongke Refining and Chemical supporting gas pipeline.1833mA super-long crossing、Sino-Russian natural gas pipelineThrough three riversWait for the super project。

In this pullback operationXZ6600 is stable and reliable，Efficient and safe，Overcome the terrain problem perfectly，Create a new record of directional drilling in China！Customers appreciate the efficiency and stability of the equipment，Highly affirm the brand and service of XCMG。
