摘要
水平井具有较大的泄流面积,可以很好的提高油井产能,提高采收率。相对于直井,相同物质条件下水平井可以增产3倍左右,甚至更多。另外,随着钻井技术的不断提高发展,近年来水平井应用越来越广泛。但在改善油田开发效果的同时,由于地层界面与水平井井眼轨迹近似平行,感应测井仪器响应与定向井就存在很大的差异,适用于直井的测井技术无法有效应用于水平井。因此,很有必要对水平井测井技术进行研究分析,本文以阵列感应测井为例,开展了相关研究,为水平井测井解释提供依据。
Horizontal wells have a large drainage area,which can improve oil well productivity and oil recovery.Compared with vertical wells,horizontal wells can increase production by about 3 times or even more under the same material conditions.In addition,with the continuous improvement and development of drilling technology,horizontal wells have become more and more widely used in recent years.However,while improving the effect of oilfield development,because the formation interface is approximately paral-lel to the horizontal wellbore trajectory,the response of induction logging tools is very different from that of directional wells,and logging techniques suitable for vertical wells cannot be effectively applied to hori-zontal wells.Therefore,it is necessary to conduct research and analysis on horizontal well logging technol-ogy.This article takes array induction logging as an example to carry out related research to provide a ba-sis for horizontal well logging interpretation.
