阵列感应测井在疑难储层开发中的应用

卫星油田的典型难题特征之一是油水同层、高阻水层广泛存在，常规测井条件下常常造成误射孔或丢失油层，给油田高效开发带来不利影响。经9口井阵列感应测井试验资料分析，这类储层阵列感应曲线对不同孔渗条件表现出不同的径向侵入特点，从储层物性与侵入特性关系出发，给出常规测井求取拟阵列曲线方法，由此建立拟阵列识别疑难储层解释方法，实现提高开发井无阵列测井情况下油水同层、高阻水层解释符合率目标。经2口井9个层试油资料验证，验证符合率达到88．9％，为该油田高效开发提供了一种有效的流体识别技术。

Array Induction Logging Application in Poor Reservoirs

Popular distribution of oil-water zone and high-resistivity water layer is one of the typical characterizations of Weixing oilfield.Conventional log usually leads to misperforation or stratum skip,and brings adverse effect to the oilfield development performance.Seen from nine wells' array induction log,array induction curves to various pore permeabilities are characterized by various intrusion behaviors.According to reservoir physical property and various intrusion behaviors,with conventional log deriving Pseudo-array curve method,Pseudo-array induction log interpretation for poor-stratum identification is established so as to improve the oil-water zone and high resistivity water layer interpretation accuracy without array induction logging.Well tests in two wells and nine layers prove the interpretation accuracy of 88.9%.Therefore,pseudo-array induction logging is an effective fluid identification technology.
