ANALYTICAL STUDIES OF THE INTERACTION OF DRILLING STRING ASSEMBLY WITH THE WALLS OF WELL WITH HORIZONTAL TAILING-IN

Abstract

In modern conditions of well construction, it is necessary to develop and apply the most effective and economically profitable solutions for oil and natural gas industry. Drilling companies need to reduce the cost of drilling wells, especially those with directional and horizontal ones. One of the ways to reduce the cost of drilling directional wells and wells with horizontal termination is to improve calculation models that optimize the selection of parameters of the elements of the drilling string assembly for directional drilling. The issue of developing a methodology for calculating the deflecting force of the drilling string assembly remains relevant when using rotary controlled systems and non-magnetic drilling collars of a telemetry module with a downhole motor for drilling directional wells and wells with a horizontal termination. In connection with the sanctions and the changing geopolitical situation, it seems relevant to
 improve the software in order to import substitution of the following products: Advantage, Wellplan, Compass, Schlumberger Drilling Office, Wellarchitect, Bhasyspro. The stiffness characteristics of the downhole tool, which can be calculated on the basis of the above software, do not allow the selection of individual elements of the drilling string assembly with the possibility of predicting the deflecting force on the bit, and thus there is no possibility of analyzing the intensity of the set of curvature of the trajectory of directional wells and wells with a horizontal termination.
 In this regard, improving the methodology for selecting the parameters of the elements of the drilling string assembly for directional drilling and increasing the efficiency of its operation is an urgent task and can contribute to the further intensive development of well drilling technology.
