摘要
油气层含水性的解释是综合解释的难点之一,确定油气层含水与否、含水比例大小,是正确评价油气层的关键。通过对辽河坳陷不同区块部分完钻井的试油数据和气测数据的统计分析,从气测录井的角度出发,总结了各类含水层的气测特征,阐述了气测录井3H(湿度、平衡、特征)解释法在各类储集层解释评价中的判别值和变化范围,在此基础上,分析了气测录井综合解释评价中应遵循的基本原则。结合储集层含水性特征的分析,参照3H法进行判别,是辽河坳陷气测录井解释评价的一种行之有效的方法。
The interpretation for water bearing property of oil and gas zones is the one of difficult points for comprehensive interpretation,and it is the key for accurately evaluating oil and gas zones to determine whether the oil and gas zones are bearing water or not and how much they contain water.By statistic analysis of the oil testing and gas logging data from part of the completed wells in different blocks,the author summarizes,in view of gas logging,the gas logging characteristics for various water bearing zones,states the discriminating values and changing ranges of gas logging interpretation 3H method in the interpretation and evaluation of various reservoirs.On this basis,he analyzes the basic principles that gas logging should follow in the comprehensive mud logging interpretation and evaluation.It is an effective way for gas logging interpretation and evaluation for Liaohe Depression to carry out discrimination by combining with the analysis of water bearing characteristics of the reservoir and referring to 3H method.
