ZPEC President Mr. Li introduced ZPEC's intention for this project and pointed out how the modified rig would replace mast and substructure while keeping other original equipment.  This would create advantages such as fast movement, low cost, and more upstate space.  He asked the users' advice on manufacturing more practical and better rigs. 

After that, ZPEC engineers respectively introduced two sets of projects and the technical advantages of the modifications.  These were highly recognized by visitors in attendance.  On site, the integrated rig movement demonstration provided a deeper understanding of the design and technology.  More than 10 drilling companies immediately showed cooperative interests and hoped they would use modified rig soon.
