  本文選題：獅子溝油田　切入點：井漏　出處：《中國石油石化》2016年S2期

【摘要】：獅子溝油田N1油藏位于柴達木盆地西部南區(qū),屬于西部坳陷區(qū)茫崖凹陷亞區(qū),獅子溝—油砂山背斜帶獅子溝構(gòu)造。該構(gòu)造淺部地層巖性疏松、成巖性差,巖性以淺棕、土黃色砂巖、泥質(zhì)砂巖及泥質(zhì)粉砂巖為主,夾砂質(zhì)泥巖及礫狀砂巖。由于淺部地層疏松、膠結(jié)性差,且地層承壓能力低,極易造成井漏。本文將對井漏的原因及采取何種預(yù)防措施以及如何堵漏進行分析。
[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.
