Experience obtained during construction of № 4548G multilateral well of Kogalym field performed by the joint fourth level of TAML classification proved the necessity of a detailed study of a well profile at the design stage. The article proposes some method of construction of a multilateral directional well profile to reduce the risks of possible complications in the intervals of clay-argillaceous rocks due to determination of the location of additional wellbore (lateral wellbore) drilling.

Calculation results made it possible to conclude that this methodology of profile designing of a a multilateral directional well, allows distributing the risks between the main and lateral wellbores, downward to the lateral wellbore decrease. Thereby it is possible to solve the problem of risk reduction of insufficient running of a lateral wellbore liner without any additional material costs. Three multilateral directional wells were subject to field testing.

The article considers packers’ operational parameters used for oil layers’ development by applying the technology of hydrostatic mud pulses generation and application. Some method of packers’ operational parameters calculation, used when washing wells for development, is suggested. Well head pressure during fluid (water) injection of into a layer is defined. The value of overpressure is fixed as well. It is proved that the necessary condition when using packers for the fluid pumping into the layer is reliable and high-quality cementing of production casing strings.

The proper choice of a sealing packer’s hermetical diameter allows effective restoration of the oil layer permeability. Physical phenomena while using packers require consideration of the energy system, oil layer being in static equilibrium before pumping out and hydrostatic fluid column, filling the well potential energy of which is converted by means of the pump, connected to the packer, into kinetic energy and then into the shock pulse energy. Energy balance equation is built. Its salvation provides getting some dynamic force that pays influence through the packer’s seal on the oil layer from the top down.

Key words: packer; rubber seals; overpressure; tearing force; coefficient of a cover; acting dynamic forces paying influence on the packer; hydrodynamic pulse.

The article analyzes the problems of formations penetration at the fields of the Sakha Republic (Yakutia). Some techniques of improving of primary penetration quality by choosing of a well rational design and optimizing of a drilling fluid composition are proved.

To penetrate the productive deposits of Osinskiy productive horizon it is proposed to use invert emulsion solutions obtained by transformation of highly-mineralized biopolymer solutions.

Cores’ permeability restoration factor when using emulsion solutions is higher than of those ones based on water solutions and reaches 85…90 %.

Key words: well; drilling; drilling mud; formations penetration; invert solution; emulsion solution; mineralized solution; complications during drilling; permeability restoration coefficient.

The article is devoted to suspension devices that are used in deep wells to cement liners and casing strings run down section by section the construction of which envisages usage for opening of circulation windows of control balls discharged into the transport drill-pipe casing string. The article discusses different calculation methods of the ball’s fall (flight) in the transport line, including the method traditionally used in Grozny branch of LLC «RN-Burenie», E.G. Leonov and V.I. Isaev method, based on application of empirical dependences of the ball falling velocity on the transport line parameters and the displacement fluid and the method of calculation based on the experimental measurement of the ball falling time through the transport line as well as the problem of preventing of the ball untimely landing on the suspension device seat that can cause accumulation of the non-fully used grout in the drill-pipe casing string and the non-fully lifting of grout in the annulus up to the suspension device. The article compares the results of the calculations performed by applying different methods on the example of cementing of 219×245 mm bottom section of the intermediate casing string at one of the wells of Grozny branch of LLC «RN-Burenie» as well as presents practical recommendations on the application of the methods considered.

Key words: liner; sectional running down of casing strings; liners cementing; suspension device; transport line; controlling ball; fall of the ball in a moving fluid; ball falling in the fluid in space-limited conditions.
