![]() ![]() Thus, rheology mechanisms of soft soil and sand are different. It is generally believed that the soft soil rheology mainly belongs to fluid rheology, while the rheology of sand and other coarse grained soil mainly belongs to plasticity rheology. Plasticity rheology mainly refers to the sliding and peristaltic between soil solid particles under shear stress. Fluid rheology is produced by rheological material. Soil rheology is divided into fluid rheology and plasticity rheology. ![]() ![]() Rheological material is refers to deformation properties similar to the solid and flow properties similar to the liquid of bound water and colloidal substances under stress. Rheological techniques have a number of quantitative physically based measurements and offer a better understanding of how soil micro-structure behaves when subject to stress. Recently rheological methods have been applied to investigate the mechanical properties of soil micro-structure. It can play an essential role in safe drilling jobs and improvement of drilling efficiency. As a result, the obtained polymer is a good rheology modifier for oil-based drilling fluids, and it can optimize oil-based drilling fluid system with good rheological properties, good static suspension ability for cuttings and environmental protection function. Moreover, the obtained polymer can improve the stability of oil-based drilling fluids greatly. ![]() The results indicated that the obtained polymer had good capacity of improvement of shearing force of oil-based drilling fluids under high temperature and high pressure conditions. Lv, J.Ī new type of polymeric rheology modifier was synthesized by suspension polymerization, and the effect of rheology modifier on the rheological properties of oil-based drilling fluids was investigated. OCR & barcode data recognition, image compression and IQA and electronic endorsement are all standard features with ARCA Scanners.Study on the effect of polymeric rheology modifier on the rheological properties of oil-based drilling fluids Each scanner features CTS’s own common API, USB2 interface, and support of TWAIN and Silver Bullet Ranger interfaces. Whether you require a throughput of 50 up to 200 DPM, the LS Series of scanners is your best choice. ARCA Check Scanners LS40, Ls100, LS150 LS515 LS515SE LS800 ARCA check scanners ![]()
