ASPE-730自动孔隙结构测试仪(恒速压汞仪)

ASPE-730 Automated System for Pore Examination

ASPE-730 自动孔隙结构测试仪（恒速压汞仪）

ASPE-730是一套用极低的注射速率注射汞自动测定微小孔隙结构结果的系统。系统包含特殊设计的极低速率的Quizix注射泵和与其集成在一起的岩心夹持器。系统设计带有便于更换的压力传感器接口和隔离阀。所有的努力都在于减少死

体积和系统的可压缩性/一致性。岩心夹持器可以夹持直径和长度各为1” 圆柱体或1cmX1cm立方体的岩心。泵体积的可监测的精度超过0.000001 cc。系统能够以0.000001 cc/s的低速率操作。泵接到一个特殊的高精度的泵控制器和驱动器上。随系统提供两个可互换的高精度（0.05% F.S.）压力传感器，范围在0-100和0-1000psi。岩心夹持器和泵系统封装在一个水平气流的气浴室中以保持测试过程中的温度恒定。箱体装配有排气孔。

FEATURES:

Uses ultra low rate controlled mercury injection

Measured data can be used to determine pore size geometry including pore throat radius and pore body radius as well a number of other parameters

Small compact system designed for maximum precision and ease of use

System includes ASPEDAS analysis software for calculation of pore throat and body diameters, subison and rison volumes, capillary pressure curves and residual/initial saturation curves as well as permeability and formation factor estimation.

The software uses Monte Carlo simulation techniques for estimating some of the resulting parameters.
