The improvement and modelling of the non-orientable floatable bottom-hole assembly

G.V. Jabbarova

The necessity of improvement and modelling of drilling string construction on the basis of float ascent principle with the property of self-alignment in set direction is established. The mathematical expression, which allowed to take into consideration the properties of materials, from which it is made in modelling of floatable bottom-hole assembly is presented. On the basis of presented mathematical model the algorithm and software of floatable bottom-hole assembly computer modelling has been developed.
