Evaluation and Field Application of a Rheology Modifier for Non-aqueous Based Drilling Fluids

Oilfield Chemicals R & D Institute, China Oilfield Services Co., LTD, Yanjiao, Hebei 065201

摘要

摘要: 研制了一种非水基钻井液用提切剂PF-MOVIS，以中海油田服务股份有限公司非水基钻井液体系为基础，在不同体系中考察了加量、老化温度、老化时间等对钻井液流变、电稳定性等的影响，同时考察了体系的抗污染能力。结果发现，随着PF-MOVIS加量的增加，体系提切效果明显增强；随着老化时间增加，体系提切效果逐渐减弱，说明PF-MOVIS随着钻进过程会逐渐消耗，在实际作业过程中需要少量多次添加；PF-MOVIS抗温能力达170℃，在170℃以下的老化温度下，PF-MOVIS对体系有显著的提切效果。同时，PF-MOVIS对体系的电稳定性有明显的增强作用；具有优异的抗污染能力；在不同的非水基钻井液体系中都有明显的提切效果。通过中试放大研究，中试产品性能与实验室小试样品性能相当，甚至优于实验室小试样品。同时现场应用结果表明，PF-MOVIS在非水基钻井液体系中有优异的增黏提切作用，应用效果良好，具有较大的推广价值。

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.
