Product Description

BRIEF INTRODUCTION Our factory and Chinese academy of science worked together and developed a new oilfield additive. The product has good anti-sloughing and thinning function in drilling fluid. It has better thinning effect than chromium iron lignosulfonate under high temperature and high density condition. At the same time it can inhabit shale hydrating efficiently and improve mud anti-sloughing property. When the well temperature reach **0℃，the mud density is higher than 1.*0g/cm3 , the drilling fluid system still has favorable heat resistance, which can prolong the maintenance period of mud , and enhance the drilling efficiency extremely. This product is a nontoxic, non-pollution, green product which has good dissemination and prospect. TECHNICAL SPECIFICATIONS: REQUIREMENT INDEX Appearance Black sticky liquid Solid content, % ≥*5.0 pH value *0~*3 Relative expansion ratio, % ≤*0.0 Thinning ratio at room temperature, % ≥*0.0 Thinning ratio after high temperature ageing for *6h at **0℃， % ≥*5.0
