摘要
介绍PDS井底取样器原理以及现场应用技术,主要分析了使用中遇到的实际问题,如预置压力、油嘴选择、转样以及泡点分析等。总结了PDS的操作实践及取得合格高压物性样品的必要条件。
Mechanical principle and technique application of positive displace sampler (PDS) is introduced, and concrete problems in the course of the operation are analyzed, such as choice of prime-pressure and choke, sample transferring and bubble point analysis and so on. Operating key-points of PDS and necessary conditions for getting normal PVT sample are summarized.
