Key words: horizontal well; drilling fluid; well completion; hydrodynamic pressure; rheologial properties; rheogram; pressure loss; equivalent circulation density.

Horizontal drilling is a highly effective method to boost output and improve productivity. As the number of horizontal wells continues to grow there is a need for assessment of the effects of drilling fluid properties and hydrodynamic pressure on the quality of well completion. The paper provides an analysis of how drilling fluid properties influence hydrodynamic pressures. The analysis is based on drilling mud testing and data processing. The research has revealed special properties of the fluids and enabled to assess the effectiveness of using the subject fluids in the geological environments of Kyrtaelskoye field.

Key words: horizontal well, anisotropy parameter, thickness of the reservoir, vertical permeability, horizontal permeability, well productivity.

The performance of horizontal wells penetrated anisotropic layers it affects a large number of factors. For well production revealed the anisotropic formation similar to the well production rate which revealed an isotropic layer is necessary either to increase the drawdown or increase the length of the horizontal section. In this paper we consider the influence of the anisotropy parameter, thickness and permeability of the anisotropic layer on the performance of a horizontal well. It is shown that at constant horizontal permeability and smaller the value of the anisotropy parameter, the greater the effect of anisotropy on performance so the greater the decrease in horizontal wells.
