摘要
面120区沙四段1砂组属于淡咸水环境下的滨浅湖沉积,层内灰质夹层较多且分布广泛,这给油藏开发带来较大影响。观察和精细描述现有岩芯,结合实验室分析数据和动静态资料,对储层进行精细描述后,重新制定出了适合本区的油、干层判别标准,并运用新标准对沙四段1砂组油层进行重新解释,指出了储层分布有利区域。
Sand Group 1 of Member Sha4 of Area Mian120 belongs to foreshore--shallow lake sediments under the circumstances of fresh-saline water. There are many calcareous intercalations which are widely distributed in the sandwich, which has a major impact on developing reservoirs. Having observed and finely described the existing core, combined with the static and dynamic data and information from laboratory analysis and finely describedf the reservoirs, this paper re-establishes the discrimination standard for oil-bearing reservoirs and dry reservoirs in this region. Also, it re-explains the oil layer of Sand Group 1 of Member Sha4 and points out the distribution of favorable reservoir region by the standard.
