一种高温超高压条件下的三腔压力分隔装置设计

A design of three-cavity pressure separation device under high temperature and ultrahigh pressure

针对高温超高压条件下三腔压力在一个容器内难建立、难传递等问题,设计了一套三腔压力分隔装置。该装置结构简单实用,不仅能稳定建立三腔压力、模拟地层结构环境,且可实现围压和孔隙压力间的有效传递。

In this paper, aiming at the difficulty of establish- ment and transfer of three-cavity pressure in a vessel under high temperature and ultrahigh pressure conditions, a three-cavity pressure separation device was designed. The structure of this device is simple and practicable, the three-cavity pressure of the stratigraphic configuration can be established stably and the effective transfer between wellbore pressure and pore pressure can be realized.
