Автоматизированная система очищения керна от пластовых флюидов «ПИК–СОК/СО₂/ТОЛУОЛ»

The PIK-SOK/CO2/TOLUOL system is designed for the rapid core samples cleaning off reservoir fluids, drilling fluids and water.   

The cleaning is carried out in the following way: being inside the chamber with excessive pressure, core samples get soaked with CO2 saturated toluene. Then the pressure inside the chamber decreases to the atmospheric one, which results in CO2 degassing and, consequently, in displacement of the sample saturating fluids. Complete core cleaning is ensured by these multiple consecutively repeated operations.

 

 

The core cleaning chamber is a vessel which is being heated. The chamber can be filled either with one full-diameter sample, or with multiple samples of smaller dimensions. However, there is no restriction to the minimum and maximum loading capacity. 

The system is supplied with a built-in recuperating module, which guarantees a complete operating cycle. 

To ensure the ease use and safety in operation, control unit system and a personal computer may be placed in a separate room.

 

Features of the system
  • Core sample dimensions : up to 110 mm in diameter, up to 660 mm long
  • 8 chambers for core placement (4 and 2 are optional)
  • Controlled chamber heating up to 100°С with a long-lasting temperature maintenance.
  • Visual control of сброса толуола.
  • Loading core into chambers by means of a particular container
  • Automated system control
