管柱式油井分层取样技术在大庆油田的应用
|
摘要
介绍了一种通过井下作业进行的管柱式油井分层取样技术,应用该技术可以获取油井生产状态下的分层段产液样品以及分层压力测试,通过物化分析及试井解释,进行油井找水、分层产能评价、新技术评价验证等工作,现场应用实例表明该项技术可以对油田开发区块在分层段的角度上进行更加精细化的分析与描述,对新技术的应用效果进行更准确的评价,为油田开发调整、评价和验证提供可靠有效的依据。
The technology of pipe string stratified sampling through the downhole operation is introduced,which can be used to acquire the zonal produced fluid samples and stratified pressure test results during normal well production. The water location,the zonal productivity evaluation and the new technology verification can be realized through the physicochemical analysis and well testing interpretation. The onsite application results show that the technology can be used to obtain more precise analysis and description for the developed zones with the application effect from the angle of the stratified layers,which can provide effective and reliable basis for more accurate evaluation,verification and adjustment of oilfield development.
