Abstract: |
This study aimed to investigate the rheological properties and the possibility of Nano (Na, Ca )- bentonites Nano products to meet the required drilling mud properties. Sepiolite (Sp) and the mixture of 2% Nano NaB with 1% Sp were collected and prepared from Iran’s oil Company (NIOC). The Nano clay performance evaluation involved the experimental tests of the rheological properties, filtration and gel strength. According to the results obtained from flow properties tests for the mixture, it was indicated that the mixture was not adequate to be a suitable drilling fluid. The main objective was to make stable dispersions with Nano bentonite and sepiolite by using a water soluble polymer as stabilizer. The changes in the rheological properties of bentonite were investigated at various concentrations of polyvinyl alcohol (PVA) to discover the stability of the dispersions. The standard API tests were applied for drilling fluid to determine the properties of dispersions. |
