Environment-friendly drilling fluid system (BIODRILL A)
BIODRILL A is a high performance and environment-friendly water-based drilling fluid, with high concentration saline as the base fluid, low molecular weight coated inhibitor and organic amine shale inhibitor as the main agent.It can be used in environment-sensitive areas attributing to its lower biological toxicity and higher repeat usage. It has been applied on a large scale in zero-descharge projects of the Bohai Oilfiled.
Excellent mud shale inhibition; Excellent sifting ability;
Excellent rock carrying capacity;
Meet I-class sea area environmental requirements;
Reusable;
Shale inhibitor PF-BIOTROL;
Coating inhibitor PF-BIOCAP
Auxiliary equipment
Various types of centrifuges are used to efficiently remove the fine solid phase in the drilling fluid, reduce the loss of liquid phase, and reduce the generation of waste drilling fluid.
CCS/DNV/ABS professional organization certification;
Strong separation ability;
Small size of equipment;
Stable operation of equipment;
Easy operation and maintenance.
