METHOD AND DEVICE FOR EVALUATING, DURING DRILLING, THE CAPACITY OF WELL FLUIDS TO FORM HYDRATES

摘要

method for the determination of the conditions of formation of gas hydrate in a well fluid, which carries out the following steps: a sample of the fluid.we place the sample in a cell calorimu00e8trie, on this sample thermogram is a witness in a temperature range between t1 and t2.we carried out on the same sample in the same range, a second thermogram and pressure ph of a hydrocarbon gas.t1 is a temperature which is sufficiently low for hydrate formation in the gas sample to ph is high enough to obtain form hydrate dissociation.we identified a peak in the second area corresponding to the thermogram hydrate dissociation and deduces a temperature of hydrate dissociation.
