【摘要】：狮子沟油田N1油藏位于柴达木盆地西部南区,属于西部坳陷区茫崖凹陷亚区,狮子沟—油砂山背斜带狮子沟构造。该构造浅部地层岩性疏松、成岩性差,岩性以浅棕、土黄色砂岩、泥质砂岩及泥质粉砂岩为主,夹砂质泥岩及砾状砂岩。由于浅部地层疏松、胶结性差,且地层承压能力低,极易造成井漏。本文将对井漏的原因及采取何种预防措施以及如何堵漏进行分析。
[Abstract]:The N1 reservoir in Shizigou Oilfield is located in the southern part of the western Qaidam basin, belonging to the Dianya depression subarea of the western depression, and the Shizigou structure in the Shizigou-Yeshan anticline. The shallow lithology of the structure is loose, the lithology is poor, and the lithology is shallow brown. Soil yellow sandstone, argillaceous sandstone and argillaceous siltstone, sand mudstone and gravel sandstone. Due to loose shallow formation, poor cementation and low bearing capacity, It is easy to cause well leakage. This paper will analyze the cause of well leakage, what kind of preventive measures to take and how to stop it.
