When the facies variations are neglected, that leads to errors in evaluating well deliverability. More accurate prediction of intervals with better reservoir properties have ultimately been achieved through the comprehensive approach, which includes integrated seismic, core, and log data study and is based on sedimentological analysis and paleoenvironment reconstruction. This approach helps to identify regularities in reservoir formation, lithotypes and facies by their genetic features.

It is shown that use of  two technologies - thermal-steam treatment and in-situ combustion at Mordovo-Karmalskoye heavy oil field allows to produce two types of oil: heavy oil of B2 type, without wax, do not differ practically from the original type, and a lighter oil of A2 type, partially diluted by the thermal cracking products. The composition of extracted oil taking into account the applied technologies changes insignificantly during the long development of the field. Gathering oil from the given field remains the nature of the mother oil, but it is less viscous and therefore more transportable.

In the article the new calculation method of definition of bottom-hole pressure in a oil well is presented. Due to fundamentally new approach to definition of parameter regarding relative slip of phases, the accuracy of pressure definition has essentially increased.

Key words: well, flowing, bottom-hole pressure, gaslift, gas and oil system, motion equation

Results of the analysis of solution of the tasks to determine the loss of axial load along the length of different types of columns based on their longitudinal and transverse strain in directional wells are presented. It is shown that the neglect of the magnitudes of transverse loads and shear forces leads to an error of calculation of loss of axial load on the friction along the length of the oil field column at its bottom spirally deformed area. The irrationality of such methods of calculation for directional and horizontal wells is confirmed.

Key words: local borehole curving, transverse-longitudinal deformation, helical spiral, pitch stability, friction coefficient, bending moment, shear load, transverse load, radius-vector, colomn curvature

The prediction of the construction residual life by load-carrying capacity in the modern aspect is considered. It is proposed to calculate the load-carrying capacity characteristic of the damaged construction using the program software based on the finite element method. The relationship between the individual life prediction and assessment of the current technical condition and load-carrying capacity monitoring of construction is considered.

Key words: technical condition, diagnostic operations, corrosion, load-carrying capacity, individual life time
