加重材料对抗高温高密度合成基钻井液性能的影响
Effect of Weighting Materials on the Properties of Synthetic-Based Drilling Fluids
摘要
Abstract
The influence of different weighting agent on the performance of synthetic drilling fluid system(SBM)were studied in this work.Based on the MODRILL drilling fluid system of China Oilfield Services Co.,LTD.,the variation of SBM performance with 2.04 g/cm3 were investigated with different weighting agent of 4.3 g/cm3 Barite,4.4 g/cm3 Barite and 4.8 g/cm3 Trimanganese tetra oxide with the ratio of 10∶0∶0、0∶10∶0、5∶0∶5、6∶0∶4、7∶0∶3、8∶0∶2、5∶5∶0.The results showed that the rheological property,emulsion-breaking voltage and high temperature and pressure filtration are affected by the different weighting agent.The apparent viscosity and the plastic viscosity would be decreased and the yield point and 6 rpm reading would be increased with the increasing trimanganese tetra oxide.The emulsion-breaking voltage would be decreased with the increasing trimanganese tetra oxide.The high temperature and high pressure filtration would be substantially increased when adding the increasing trimanganese tetra oxide.The above conclusions were verified in the filed test by studying the effect of weighting agent on the performance of synthetic drilling fluids.关键词
