| 中文摘要:塔河油田是我国重要的油气产区，井漏的发生对油气的安全生产危害极大。塔河油田的井漏问题会多发生在二叠系、石炭系以及奥陶系层位，原因大致可归纳为：二叠系地层裂缝发育、石炭系地层敏感性高、奥陶系缝洞型地层漏失空间大。本文对塔河油田的地质特点进行总结，对由此而产生的井漏等井下事故问题进行了阐述与分析，总结了塔河地区防漏堵漏的技术方法，对以后该区域的开发利用具有一定的借鉴参考价值。 |

| Abstract:Tahe Oilfield is an important oil and gas production area in China, and lost circulation endangers production safety in the field. Lost circulation in Tahe Oilfield happens mostly in the Permian, Carboniferous and Ordovician strata. The causes can be summarized as below: well developed fractures in the Permian strata, highly sensitive Carboniferous strata and large crack-holes in the Ordovician strata. In this paper, the geological characteristics of Tahe Oilfield are summarized with the resulting down hole incidents such as lost circulation expounded and analyzed. At length, the technical methods for lost circulation prevention and plugging in Tahe Oilfield are summarized, providing some reference for the future exploitation in this region. |
