摘要
针对油层低压、低渗的地质特点,分析了泡沫钻井液的保护油层的机理,研究了泡沫钻井液的性能与温度、压力、时间及各种试剂的关系。现场应用实例结果表明:泡沫钻井液性能稳定,携岩、携砂能力强,润滑性能好,有抗污染性能;泡沫钻井液,多被用于裂缝发育、漏失严重、低压或超低压地层,并能有效地降低事故发生率,防止井壁坍塌;泡沫钻井液能满足地质录井要求,能确保施工全过程的优质高效。
The conception, elements, performance, and history of foam drilling fluid are described. Reservoir protection mechanism and relation performance to temperature, pressure, time and ingredient of foam are analyzed. Then testify the function that the drilling fluid in exploiting reservoirs by effect that the drilling fluid are put into a few wells in field.
