Pressure-volume-temperature (PVT) sample barrel and sample transferring tool

Pvt样筒及转样工具

Abstract

The utility model relates to a pressure-volume-temperature (PVT) sample barrel and a sample transferring tool. The PVT sample barrel comprises a sample storage cylinder upper joint, a sample storage cylinder barrel, a sample storage cylinder lower joint and a sample storage cylinder piston, wherein the sample storage cylinder piston is arranged in the sample storage cylinder barrel; the sample storage cylinder upper joint and the sample storage cylinder lower joint are respectively connected with the upper end and the lower end of the sample storage cylinder barrel; an upper channel communicated with the upper end of the sample storage cylinder barrel is arranged in the sample storage cylinder upper joint; a lower channel communicated with the lower end of the sample storage cylinder barrel is arranged in the sample storage cylinder lower joint; a bleed valve for controlling the upper channel to be switched on and switched off is arranged on the sample storage cylinder upper joint; and a gas inflation starting valve for controlling the lower channel to be switched on and switched off is arranged on the sample storage cylinder lower joint. The sample transferring tool comprises a separation bottle, a gas dissolving bottle, a pressure regulation combination and a gas flow meter, wherein a four-way joint is arranged on the separation bottle and respectively connected with the PVT sample barrel, the pressure regulation combination and the gas dissolving bottle through switching joints. The PVT sample barrel and the sample transferring tool have simple structures and are used safely and suitable for storage and extraction of underground stratum liquid.
