涪陵工区测井系列优化选择探讨

Discussion of Optimization Selection of Logging Suite in Fuling Workzone

选择一口井测井系列,主要依据井的区域地质情况,井所钻探的地层是否存在邻井、井所钻探的油藏是否处于生产开发期等因素。测井系列的选择应满足油气勘探、开发的需要,满足地质和工程评价需要等要求。裸眼直井段测井系列选择,除必测项目外,建议增测地层倾角、微电阻率成像、ECS元素俘获测井项目。主要解决地层剥蚀面识别问题。裸眼水平井段测井系列选择,建议增测微电阻率成像、核磁共振、ECS元素俘获测井项目。套管井测井系列选择,建议增测存储式测井项目。创新优选的测井系列和资料采集项目符合中石化南方公司的勘探要求,为涪陵工区页岩气低成本和高效开发提供了必要的技术支持。

Selecting logging suite for one well is mainly based on the factors that what about its regional geology, whether there is another well nearby its drilling formation and whether the drilling reservoir is in development peri- od, and should meet the requirements of oil-gas exploration and development as well as geological and engineering assessment. As far as logging suite for open-hole vertical section concerned, it is suggested to add dip angle log- ging, microresistivity images logging and ECS element trapping logging besides regular logging items so as to distin- guish the plane of denudation. As for open-hole horizontal section, it is better to add microresisfivity images log- ging, nuclear magnetic resonance logging and ECS element trapping logging. As for cased wells, it is suggested to add storage style logging. Making an innovation in optimization selection of logging suite and data acquisition accords with exploration requirement of Sinopec Southern Company and provides necessary technical support for low--cost and high--efficient development of shale gas in Fuling Workzone.
