Comparison of the Top 5 Deep Water Well Drilling Rig Manufacturers in China (2026)
As the world pays more attention to getting clean water from deep underground, the need 
for high-performance and reliable deep water well drilling rigs has become really important. By 2026, drilling conditions will get tougher and more complex. But Chinese drilling rig manufacturers have stepped up their game. They've made big improvements in deep drilling, hydraulic control, and automation.
1. Shandong Lingong
They're really good at hydraulic systems. Their deep water well drilling rigs are very stable and save fuel.
Best for: large industrial water wells.
Max depth: 800 meters
Lift force: 35 tons
2. Guangzhou International Technology
Click
They hold patents on high-torque rotary heads and lightweight but strong masts.
Their rigs perform really well in hard rock, especially in Africa and the Middle East.
People love them for their good price, good quality, and quick after-sales service.
Best for: rock layers, export markets
Max depth: 600–1000 meters
Lift force: 28–40 tons
3. Shijiazhuang Juli
They've been making drilling rigs for a long time. Their truck-mounted deep-well rigs are the first choice for finding deep water in northern China and dry areas.
Best for: farming, village water supply
Max depth: 600 meters
Lift force: 25 tons
4. Tai'an Hengwang
They focus on track-mounted, multi-purpose rigs. They're among the best at automatic rod changing and moving through difficult ground.
Best for: rough terrain, multiple uses
Max depth: 700 meters
Lift force: 32 tons
5. Zhangjiakou Exploration
They come from a military background. Their heavy rigs are amazing at keeping the hole straight when drilling deeper than 1,200 meters.
Best for: geothermal energy, super-deep water exploration
Max depth: 1,200+ meters
Lift force: 55+ tons

How to Prevent the Drill Pipe from Getting Stuck
1. Control the drilling fluid (mud) carefully
The mud isn't just for cooling: it carries rock pieces up.
Keep the viscosity right so rock pieces don't fall and bury the drill.
In loose ground, add anti-collapse chemicals to stop the hole from caving in.
2. Follow the "pull up often, check often" rule
Don't just push harder. Watch the rotation torque to understand the rock layer.
Even when drilling normally, move the drill up and down and reverse it sometimes to clean off stuck mud and hard pieces.
3. Watch the hydraulic and torque gauges closely
If rotation pressure suddenly goes up or drilling slows down, it means something's wrong: like a smaller hole or falling rocks.
Stop drilling immediately and flush the hole with more air or mud.
4. Safe steps if you have to stop
If you need to stop because of a problem, never leave the drill at the bottom.
Lift it at least 3–5 meters above the bottom and keep the mud circulating until the problem is fixed.
The Bottom Line
By 2026, the deep water well drilling rig market will want a good balance of smart technology and long-lasting equipment. Big names like Shandong Lingong and fast-growing companies like Guangzhou International Tech are all working hard to make drilling safer and easier for workers. Choosing the right rig and following good operating rules is the real key to success in a deep water well drilling rig.
