摘要
在试油统计基础上,根据油层、干层和低产油层绘制孔隙度、深度、压实指标等交会图的研究及具体分析,认为储集层孔隙度有效下限值为9%,压实减孔量为34%。同时,在全面了解各构造带中浅储集层物性的基础上,选取部分代表井分析,确定储层深度有效下限值,台北凹陷总体上表现出"北浅南深、东浅西深"的特征,并指出台北凹陷体罗系储集层在有效下限以下勘探具有较大的风险。
With oil test statistics, according to study and analysis for cross plot of porosity and depth and compaction target, which is drawn from oil layer and dry zone and low pay zone, effective inferior boundary of reservoir porosity is regarded to be about 9%, porosity reduction resulted from compaction is 34%. Simultaneously, on the basis of fully understanding for physical property of middle and shallow reservoir of various structural belts, effective inferior boundary value of reservoir depth will be determined by analyzing part of representative wells selected. Generally, Taibei depression is characteristics of 'shallow in north and east, depth in south and west'. It has huge risk to survey Jurassic reservoir of Taibei depression below effective inferior boundary.
