文章介绍了一种新型的在合采油井正常生产状态下分层腔式取样及测压技术;阐述了腔式取样器的机械结构、取样工艺原理,以及通过原油烃色谱指纹分析技术利用标准模版监测周边合采油井分层产能状态的技术。
The article introduces a new type of layered cavity sampling and manometry technology in the normal production state of a joint production well. The mechanical structure of the cavity sampler, the principle of the sampling process and the principle of using the standard stencil by the crude oil hydrocarbon chromatographic fingerprint analysis technique are described. Technology to monitor the status of stratified production capacity of the nearby production wells.
