METHODS FOR DETERMINING THE WATER CONTENT OF A DRILLING FLUID USING WATER PHASE SALINITY

摘要

Methods for monitoring a drilling process that uses a drilling fluid are described. The methods include measuring an initial salinity of a water phase of the drilling fluid, diluting the drilling fluid with a known amount of water to form a diluted drilling fluid, measuring a salinity of a water phase of the diluted drilling fluid, determining an initial relationship between a salt content and a water content in the drilling fluid using the initial salinity of the water phase of the drilling fluid, calculating an initial water content of the drilling fluid using the measured salinity of the diluted drilling fluid and the initial relationship between the salt content and the water content in the drilling fluid, and adjusting one or more drilling parameters in response to the calculated initial water content.
