DFQ-200 Multi-functional Drilling Rig
I. Application and Features
DFQ-200 drilling rig is a lightweight, high efficiency and multi-function drilling equipment,it adopts crawler chassis, self-propelled, easy to transport. It adopts to two kinds of working way---with mud pump or air compressor, strong applicability.
It is widely used for water well drilling,geothermal air-conditioning project and other boreholes, especially applicable to mountain area and rock formation water engineering.
Much higher efficient than the traditional rotary drill rigs, creating the considerable economic benefit for users. Especially solve the problems to drill very hard rocks that the traditional rotary drilling rig meet, our DFQ-200 is able to work efficiently under all kinds of geological conditions.

III. Details
How to choose a suitable drilling rig?
1. What will you do using drilling rig?
---For water project, core sample, soil test, mineral prospect or others?
2. The depth you need?
---For water well, generally, 30-200m. For core sample, 30-600m, even more.
3. Any requirements to hole diameter?
---Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional.
4. Working land condition?
A. soil, sand, weathered land, etc. soft stratum.
B. soil, sand, soft and hard rock stratum, mixed one.
C. Mainly hard rock, like granite.
