摘要
测开资料标准化是油藏描述中必不可少的基础工作,是实现由单井解释到多井评价的关键。枣园油田枣南孔一段无全区分布稳定的标准层。本文根据该区复杂的地质特征,选择稳定的非渗透层组作为“视标准层”,通过确定其特征峰值,区域上利用趋势分析技术,局部地区利用直方图校正、均值校正等技术,求取标准化值。资料处理结果表明,所采用的标准化方法,依据充分,效果明显,不仅提高了解释精度,减少了解释盲目性,同时也提高了多井间资料的可比性,并为更准确地求取油藏描述中所必需的参数奠定了基础。
Normalization of well logging data is an indispensable basic work in reservoir description.It is a key to multi-well evaluation.Since there is no index bed existing in the whole area,a stable and non-permeable bed which we called″quasi index bed″was chosen in accordance with the complex geological features of Zaonan K1 Formation.By means of determining characteristic peaks,the value of normalization was obtained through regional trend analysis and local histogram, overlap and mean corrections.Results show that this method is effective and the precision of single well interpretation and the correlation of multi-well are greatly improved.This method lays the founda- tion for later computation of all necessary parameters for reservoir description.
