摘要： A method of quantitative analysis of drilling fluids comprising subjecting an untreated wet sample of the fluid to a reflectance infrared spectroscopy technique, typically attenuated total reflectance spectroscopy, and comparing the spectrum obtained with spectra obtained from calibration samples of fluids of known composition. The sample can be obtained directly from the flowing mud with no preparation or alternatively the sample might comprise a prepared sample which is re-suspended in a liquid phase carrier. The sample can also be analysed for non-spectral properties which might also provide useful information in conjunction with spectral data. The method requires little or no sample preparation and can be used to quantitatively analyse both water-based and oil-based drilling fluids using a continuous in-line and/or on-line arrangement.

摘要： A method of quantitative analysis of products, such as barite, bentonite or polymers, in a drilling fluid circulating in a wellbore being drilled is described. The method includes the steps of sampling the drilling fluid, and analysing the sample to determine the density of the fluid and the weight fraction of solids in the fluid. In addition, a known weight of the sample is dried to constant weight so as to obtain the products under the form of solids, which solids are analysed by an infrared spectroscopy technique. The concentration of the products in the drilling fluid is then determined. The method can be applied to the control of the drilling operation by monitoring the quantity of products added to the drilling fluid, such as barite and polymers, or a product coming from the borehole wall or the underground formation being drilled. The invention also applies to the control of the working condition of the mud solids equipment.

摘要： A method of quantitative analysis of solids carrying drilling mud and removed from a drilling fluid circulating in a wellbore being drilled is described. The method comprises the steps of: sampling the removed solids, and analyzing the sample to determine the density of the solids and their weight fraction, drying a known weight of the sample to constant weight so as to obtain the solids in the form of dry solids, and analysis of the latter by an infrared spectroscopy technique. The concentration of the substances in the removed solids is then determined. The method can be applied to the control of the drilling operation by monitoring the quantity of products added to the drilling fluid, such as barite and polymers, or a product coming from the borehole wall or the underground formation being drilled. The invention also applies to the control of the working condition of the mud solids equipment.

摘要： In the rotary drilling of oil wells a drilling mud is used both to transport the cuttings up to the surface and to impose an hydrostatic pressure on the walls of the borehole. For these functions the mud must for example have an acceptable viscosity and density. It is therefore important to monitor the characteristics of the mud, and to keep them within certain limits. Only recently, however, has drilling practice recognized the importance of monitoring the mud's ionic composition. The various techniques proposed involve separation of the mud into liquid and solid portions, and analysis of these. Though they have proven useful, yet there are a number of problems. For example, the separation has not always been easy, and the available techniques often may not satisfactorily remove the fines. The invention suggests that these two problems, at least, can be overcome by the relatively simple expedient of first acidifying the mud sample, for acidification both causes the mud particles to flocculate, and so be more easily separated off, and causes the active fines to dissolve. In a preferred embodiment hydrobromic acid is employed, together with tetramethylammonium bromide (a displacement agent enabling the mud solid's Cationic Exchange Capacity to be measured), the separation is by filtration, and the analysis is by ion chromatography--and the results are fed into a computer model that then calculates the original mud components.
