Evaluation and Field Application of a Rheology Modifier for Non-aqueous Based Drilling Fluids
摘要
Abstract
A rheology modifier for non-aqueous based drilling fluids was prepared in this work.Based on the drilling fluid systems of China Oilfield Services Co.,LTD.,the influence of dosage,aging temperature and aging time on rheology and electrical stability performance of drilling fluid were studied.The anti-pollution ability were also studied in this work.The results showed the gel strength was obviously improved with the increasing dosage and weakened with the increasing aging time.It indicated that PF-MOVIS is gradually consumed during drilling process and it need to be added with a small number of times in the actual operation process.The temperature resistance of PF-MOVIS reached 170℃.It showed an obvious better gel strength under the temperature of 170℃when adding the PF-MOVIS.Moreover,PF-MOVIS could obviously improve the electrical stability properties.It has excellent anti-pollution ability and reservoir protection performance.According to the pilot scale study,the performance of the pilot product was comparable to even better than that of the lab sample.At the same time,the field application results showed that PF-MOVIS obviously increased gel strength for non-aqueous based drilling fluids.The field application effect was very well and and it has great popularization value.关键词
