Introduction and Application of Oil-based Drilling Fluid Oil Based Mud Comprehensive Treatment System

1.Introduce about oil-based Drilling Fluid

 

1.1 Introduction About Additives

Primary Emulsifier ZOD-053A, natural active substances modified product, the highest applicable temperature 150 ℃(BHCT)

Primary Emulsifier ZOD-053B, natural active substances modified product , the highest applicable temperature 230 ℃(BHCT)

Wetting Agent ZOD-059A polyether surfactant grafted product, the highest applicable temperature 150 ℃(BHCT)

Wetting Agent ZOD-059B natural oil condensate graft modified product, the highest applicable temperature 230 ℃(BHCT)

Second Emulsifier ZOD-054 long chain alkyl surfactants modified product, the highest applicable temperature 230 ℃(BHCT)

Fluid Loss Additive ZOD-043A polymer modified materials, the highest applicable temperature 150 ℃ (BHCT)

Fluid Loss Additive ZOD-043AB heavy rubber modified bituminous oxide materials, the highest applicable temperature 230 ℃(BHCT)

 

The main features of the treatment agents

☆apply to white oil, diesel oil, oil-based drilling fluids formulation of synthetic based oil liquid;

☆apply to oil to water ratio from the whole to the oil to water ratio 65/35. Under the condition of low water ratio it can meet the requirements of the breaking voltage;

☆  The two kinds of primary emulsifiers have mention cutting active, without extracting agent they can keep suspension effect of drilling fluid to drill cuttings, effectively reduce the cost of system;

☆Second emulsifier, wetting agents having a role of improve viscosity, easy to adjust and control the rheological f property of drilling fluid;

☆High-density system rheological properties can still meet the requirements of pseudoplastic drilling fluid model with good rheology.

☆All the treatment agents are self-produced, and we master the core technology of the treatment agents, can effectively control quality.
