DSP-1 adopts the design of molecular structure. DSP-1 is polymerized with solvent method through the optimization of monomer of salt resistance and high temperature resistance.
NP-1 is a multi-polymer composed of alkane sulfonate, alkyl ester, crosslinking agent. It forms nano-solid sealing material through special technology.
AP-1 is a new type of shale inhibitor used in high-performance water based drilling fluid, which is a poly-amine-modified polyether polyols shale inhibitor.
NS-1 is the latest development of a hydrophilic modified silicon dioxide dispersions. NS-1 particle size distribute in the range of 1-100nm, which can seal nanoscale pore of shale effectively.

Drilling Fluids Systems

Ultra-high density composite brine drilling fluid system D-ULTRAWEI

Aiming at the technical problems such as fluid loss reduction, rheology and inhibition coordination, and well wall stability of ultra-high density drilling fluid system under high temperature and high pressure conditions, the ultra-high density composite brine drilling fluid system with a density of 2.6g/cm3 was developed by carrying out research work such as optimization of high-temperature resistant drilling fluid treatment agent, optimization of drilling fluid particle size distribution, and optimization of drilling fluid system composition.

Ultra-high temperature water-based drilling fluid system D-SuperHT

Ultra-deep Wells or geothermal Wells often face formation temperatures of more than 220 ° C in drilling construction, and deep Wells often drill salt paste layer, so the company has developed ultra-high temperature water-based drilling fluid system with temperature resistance of more than 220 ° C.
