drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. there are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. the present work aims are study on the modified drilling mud properties by using the ...

The rheological regulation of the “three high” (high temperature, high density and high salinity) water-based drilling fluid is a worldwide problem due to the combined influence of temperature, solid content and salinity. This paper investigates the factors and regulation methods about rheological property of “three high” water based drilling fluid, and the effects of clay, salinity and weighti...

Information transmission is an important part of the wellbore trajectory automatic control system. Combined with the characteristics of the guided drilling system, drilling fluid pulse is selected as a tool for trajectory control. Negative pulse transmission of drilling fluid is one of the key technologies to realize wellbore trajectory automatic control. In this paper, the working principle of...

   Drilling fluids are an essential component of the rotary drilling process used to drill for oil and gas on land and offshore environments. The injection of this nano particle into drilling fluid increases the viscosity levels fluids. In these experiments, the rheological properties of the fluid including apparent viscosity (AV), plastic viscosity (PV), yielding point (YP), mud c...

maybe viscosity in drilling fluid is the most important parameter because cutting removal from well are task of viscose fluid. if viscosity of fluid is less than particular value, cutting will settle down in well and drilling operation will be stopped. in this study, synthesis of alumina/polyacrylamide nanocomposite through solution polymerization method was performed. rheological behavior of m...

Filtration index of the drilling fluid is an important parameter of well drilling, especially at drilling-in the reservoirs. Standard parameter in the study of drilling fluids is static filtration index. At the same time, it is more feasible to determine dynamic filtration index, if considering actual conditions of the well. Use of polymer carbonate-weighted drilling fluids is advisable at dril...

In a recent decade, application of nanofluid as a candidate for heat transfer medium has gaining an increasing attention due to its unique advantages. In the light of its unique advantages, it has been utilized in different industries such as oil and gas industries. In this work aims at improving thermal conductivity of the water-based drilling fluid by using the CuO nanofluid additive. CuO nan...
