| 摘 要： | 通过静置沉降和乳滴聚结实验研究了SN—1对不同油水体系的乳化稳定作用,并探讨了SN—1对乳状液稳定作用的机理,介绍了SN—1在水包油型、油包水型乳化钻井液和油包水解卡液中作为主、辅乳化剂的现场应用情况。结果表明,SN—1是一种乳化能力较强的固体乳化剂,用于钻井液中可显著提高乳化钻井液的稳定性,增强钻井液的润滑性能和降滤失性能,防止粘卡等复杂事故发生,此外,SN—1还具有用量少,运输、存放和使用方便等优点,适用于各种钻井液。

| Abstract: | The function mechanism of solid emulsif ier SN - 1 is studied by static settlement and emulsion drop aggregation tests. SN -1 can be used in water-in - oil emulsions while its concentration is below 1. 4% , and oil-in -water emulsions while its concentration is over 1. 4%. Tests at horizontal and cluster wells indicate that SN - 1 possesses good emulsifying effect , improves mud lubricity, and can be used in formulating releasing stuck fluid. |
