Synergistically using layered and fibrous organoclays to enhance the rheological properties of oil-based drilling fluids
Source abstract
Abstract
Abstract Layered organo-montmorillonite (OMt) is widely used as the rheological additives in oil-based drilling fluids. Recently, fibrous organoclays, such as organo-palygorskite, had been reported as the rheological agent in oil-based drilling fluids. These organoclays showed different rheological properties and mechanisms. In this work, the joint use of OMt and OPal in oil-based drilling fluids was investigated. The optimized organoclays were prepared according to the previous reports and characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, thermal analysis. The rheological properties of mixed organoclays at different mass ratios were tested in comparison with the single organoclay. Viscous flow behavior, viscosity and thixotropy were summarized. The synergetic use of OMt and OPal could improve the rheological properties of oil-based drilling fluids, even aged at 200 °C. The optimal mass ratio of OMt to OPal was 1:1. The rheological mechanism of mixed OMt and OPal in oil was concluded based on the X-ray diffraction results of organoclay/oil gels. The presence of fibrous OPal enhanced the network structure of layered OMt and prevented the network structure from collapse by interlacing among the nanolayers.
