摘要:

新疆克拉玛依油田二中区油藏为砾岩油藏,注水开发后,该区储层的地层电阻率有比较大的变化。通过水驱油和油驱水实验研究,发现淡水注入后,储层含油饱和度与岩石电阻率有多解关系,岩电参数也随着矿化度的变化而改变。研究结果为水淹层研究和测井评价奠定了基础。

关键词: 含水饱和度, 水驱油, 注入水, 岩电参数, 砾岩

Abstract:

The reservoir is a conglomerate reservoir in the second area in Karamay oilfield, Xinjiang. After water injection, the resistivities of formations change severely. Through study on water displacement oil and oil displacement water, it is revealed that there are polykeys of the relation between water-hold saturation and rock resistivity in low salinity water injection formation, and electric parameters of rocks change with salinities. The results provide experimental data for analysis of drowned well and well logging.

Key words: water saturation, water displacement oil, oil injection water, rock electric parameter, conglomerate
