Environment Friendly Water-Based Drilling Fluid Using Natural Vegetable Gum

Abstract

This paper reported the formulation and the laboratory analysis of TLJ-1 vegetable gum drilling fluid with the temperature resistance capability up to 140 ºC. Based on the single-factor method, TLJ-1 is chosen as the main treatment agents for the fluid, LV-CMC and PEG taken as the filtrate reducer, QS-2 taken as the rigid filling particles, the three formulations, i.e., the low-solids drilling fluid, the solidsfree drilling fluid and the weighting natural vegetable gum drilling fluid have been presented. The laboratory analysis has demonstrated the good temperature resistance capability of the presented TLJ-1 vegetable gum drilling fluids for environmental safety.
