Wellbore fluid testing apparatus and methods

摘要

A system for testing a wellbore fluid includes a test chamber having first and second platens therein. The chamber is in a thermally insulating enclosure. The enclosure includes a heating element. The platens simulate response of the wellbore fluid through an hydraulically induced fracture in subsurface rock formation. The system includes means to control a distance between the platens. A pump introduces the wellbore fluid into a space between the platens and another pump introduces a pressure test fluid into contact with the wellbore fluid. A respective pressure sensor is in fluid communication with a discharge side of each pump, and a sensor is included to measure a parameter related to the position of the second platen or the space between the platens. A data acquisition and control device is configured to detect signals from the respective pressure transducers and the sensor.

1. An apparatus for testing properties of a wellbore fluid, comprising:
a test chamber having a first platen and a second platen therein, the platens configured to simulate response of the fluid when moved through an hydraulically induced fracture in a subsurface rock formation; means for controlling a position of the second platen with respect to the first platen during testing; a pump for introducing the wellbore fluid into a space between the first platen and the second platen; a pump for introducing a pressure test fluid into contact with the wellbore fluid; a respective pressure sensor in fluid communication with a discharge side of each pump and a sensor configured to measure a parameter related to position of the second platen; a thermally insulated enclosure in which the test chamber is disposed; a heater for maintaining a selected temperature in the enclosure; and a data acquisition and control device configured to detect signals from the respective pressure transducers and the sensor.
