Abstract:

The rheological properties of drilling muds are critical for achieving optimal performances during drilling operations. In this study, bentonite, tannin, and xanthan gum were utilised as water-based drilling mud additives to enhance the rheological properties. The Response Surface Methodology (RSM) with Box-Behnken Design (BBD) was used to investigate the additive's effect on the rheological properties of the drilling muds. The concentration of bentonite, tannin and xanthan gum were considered as the independent variables, while plastic viscosity (PV), apparent viscosity (AV), and yield point

Abstract:

The currently common method for the automated real-time accurate measurement of drilling fluid rheology is the straight pipe measurement. However, the pulsating flow generated by the pumping equipment often leads to significant data errors in pressure difference and flow measurement, resulting in low accuracy of the calculated rheological parameters. To address the issue of data errors caused by pulsating flow, this paper proposes a correction model for straight pipe drilling fluid rheology measurement under pulsating conditions.
