【摘要】 ＭＥＧ泥浆是国外最近才研制成功的一种新型无环境污染的油基泥浆替代体系。扼要介绍了ＭＥＧ母液和泥浆的性能及作用机理，给出了在国内首次开展的关于ＭＥＧ新型泥浆的部分试验结果。试验结果表明，研制出的ＭＥＧ泥浆确实具有优良的抑制性、润滑性、储层保护特性和抗污染能力。更多还原

【Abstract】 MEG drilling fluid is a recently developed environmentally acceptable water based mud with its performance approaching the oil based muds. This paper not only introduces the properties of MEG base fluid and drilling fluid as well as mechanism, but also presents a part of the results of the study on MEG drilling fluid first developed at home. The study results show that the MEG fluid has superior inhibition, lubrication, formation damage prevention and contamination resistance characteristics.更多还原
