Definitions
- the viscosity of a drilling fluid is commonly increased to enhance the fluid's drill cuttings-transport capability.
- pumping high-viscosity fluids can be disadvantageous to the economics of oil well drilling by effecting high friction pressure, requiring higher horsepower pumping equipment and subsequent higher fuel expenditure.
- Higher drilling fluid viscosity is advantageous only in the annular space between drill pipe and borehole, where drill cuttings are located and from which they need to be removed.
- lower viscosity is preferred for the drilling mud so as to minimize frictional pressure loss.
- the narrower flow channels inside the drillpipe and drill bit cause the drilling fluid to undergo a higher shear rate, which also increases frictional pressure loss.
- the crosslink activator can effect the crosslinking of the polymer.
- the drilling fluid containing the crosslinking and crosslinked polymer is circulated in the wellbore where it entrains drill cuttings.
- An advantage of this method is that highly viscous fluids may be used for removing drill cuttings from the well without forcing such viscous fluids through the drill bit nozzles and hence without taxing pumping equipment. Further, such viscous fluids may be used as the drilling fluid, without altering the density of the drilling fluid, and without stopping the drilling for a sweep of the wellbore with viscous fluid to remove drill cuttings.
- crosslink activators which are either the crosslinking agents or pH-adjusting compounds, are encapsulated with a material that preferably helps to delay their interaction with the crosslinkable polymer in the drilling fluid, such as, for example, a material that is insoluble or only slightly soluble in an aqueous environment. This delay mechanism allows the drilling fluid to become viscosified or crosslinked at desirable times and locations.
- a material that preferably helps to delay their interaction with the crosslinkable polymer in the drilling fluid such as, for example, a material that is insoluble or only slightly soluble in an aqueous environment. This delay mechanism allows the drilling fluid to become viscosified or crosslinked at desirable times and locations.
- the drilling fluid according to the invention is prepared by metering the drilling fluid concentrate or used drilling fluid that has been uncrosslinked and had drill cuttings removed into a blender wherein it is mixed with additional water and/or additives which also may be metered into the blender or otherwise added to the fluid.
- the mixture may then be pumped, preferably simultaneously, out of the blender and into the drillpipe, wherein it proceeds downhole.
- the time period, starting from when the metering, mixing and pumping process starts to when the formed drilling fluid reaches the drill bit and subterranean formation to be drilled, is usually and preferably a time period of only several minutes. This ease and speed of preparation allows changes in the properties of the drilling fluid to be made on the surface as required during the time the drilling fluid is being pumped.
