GRAPHICAL EVALUATION OF CUTTINGS TRANSPORT IN DEVIATED WELLS USING BINGHAM PLASTIC FLUID MODEL

Abstract:
The efficient removal of drilled cuttings from deviated wellbores is a critical aspect of drilling operations. The transport of cuttings is influenced by various factors, including well deviation, fluid rheology, and flow rate. In this study, a graphical evaluation approach is proposed to assess cuttings transport in deviated wells, specifically using the Bingham plastic fluid model.

The Bingham plastic model is widely used to describe the rheological behavior of drilling fluids, which exhibit a yield stress and a linear relationship between shear stress and shear rate once the yield stress is exceeded. By incorporating this fluid model, the graphical evaluation method aims to provide a practical and intuitive tool for analyzing cuttings transport in deviated wells.

The proposed approach involves constructing a graphical representation of the critical flow velocity, known as the slip velocity, as a function of inclination angle and fluid properties. The slip velocity represents the minimum fluid velocity required to initiate the movement of cuttings. By comparing the actual fluid velocity in the wellbore with the slip velocity, the graphical evaluation method enables the identification of regions prone to cuttings accumulation or settling.

The graphical evaluation of cuttings transport in deviated wells using the Bingham plastic fluid model offers several advantages. Firstly, it provides a visual representation of the expected cuttings transport behavior, aiding the understanding of critical zones. Secondly, it allows for the optimization of drilling parameters, such as flow rate and mud properties, to minimize the risks associated with cuttings accumulation. Lastly, the approach can assist in the design and selection of appropriate drilling fluids for deviated well drilling operations.

To demonstrate the applicability of the proposed method, hypothetical case studies and sensitivity analyses can be performed using various wellbore geometries and fluid rheological properties. By comparing the graphical evaluation results with field observations and existing theoretical models, the accuracy and reliability of the approach can be assessed.

In summary, the graphical evaluation of cuttings transport in deviated wells using the Bingham plastic fluid model offers a valuable tool for understanding and optimizing drilling operations. By visualizing the critical zones prone to cuttings accumulation, this approach can contribute to enhanced drilling efficiency and reduced operational risks in deviated wellbores.
