摘要
水平井测井解释中薄砂层的识别始终是一个棘手的问题,特别是在大家熟知直井中测井响应及储层评价的前提下。本文作者主要从水平井与直井测井响应差异的角度来研究水平井测井解释的难题,针对薄砂层水平井的问题首次提出了利用微球型聚焦电阻率测井,结合自然伽马和自然电位测井来确定岩性界面的方法。以塔里木地区的一口水平井为例,借助于水平井测井解释软件说明该方法的可行性,为进一步提高水平井钻探的成功率和测井资料解释精度提供了可靠的依据。
It is a delicate question that recognizes lithology in thin sand to log interpretation of horizontal well. Especially people have known very well the log response and reservoir evaluation of straight well. The puzzle has been researched in the paper on difference between horizontal and straight well. In allusion to horizontal well thin sand layer, the article puts forward a method of using MSFL resistivity logging together with GR and SP searching litho logic interface for the first time. It is feasible that the new method apply to a case of horizontal well in Talimu field. It has been validated by a horizontal well logging integrated interpretation software. Thus,it is enhanced greatly in drilling success rate and the precision of log interpretation of horizontal well.
