Drilling Fluid and Completion Fluid | Year: 2010

The Kenirake oil-field is located in the east of strand Caspian Sea basin prospect areas of Kazakhstan republic. In this areas, the complex accidents always occurred, such as well blowout, well leakage, well collapse, sticking of drill tools, and so on. According to the geologic characteristics of the region and the demands of the side tracked wells, high density and saturated brine poly-sulphonated drilling fluids were used. In K7011 and K106 wells, the application results showed that the mud systems had stable properties, strong shale inhibition and excellent rheological property.The oil soluble and acid soluble temporary plugging agents were added into the drilling fluids. As a result, it ensured the reasonable distribution of particle fraction and good plugging capacity. Accordingly, the oil and gas formation was effectively protected.
