The purpose of the work: to improve the labyrinth compressors to increase the productivity, increase the resistance to corrosion, thereby increasing the stability index of the compressor compressor node, and reducing the compressor interstage pressure to atmospheric pressure, in order to reduce the pressure acting on the compressor. Object of the work: Improvement of piston compressor connectors.
For this, let's examine the use of different types of compressors in a piston compressor:
One of the most common problems in production is the problem of malfunctioning of piston compressors. This affects the productivity of the compressor. In order to increase the productivity of piston compressors, different types of compressors are used: rubber compressors, cuff, graphite, face compressors.
To overcome this problem, it is appropriate to use a new type of labyrinth connectors. Thus, unlike ordinary graphite capacitors, labyrinth capacitors are distinguished by their long-term use, easier installation and, most importantly, more stability. Simple graphite-type coils cause some problems during installation. The main one is the problem of creating a complete mold. Labyrinth coils are easier to install than these coils and the mold is fully ensured. If there is any release during the process, as a result of the pressure difference between the labyrinths, the pressure of the product coming out of the last labyrinth is equal to atm pressure.
Taking into account the above, we see that the use of labyrinth clamps is suitable for increasing productivity during the operation of compressors, for eliminating out-of-order discharges and for solving the problems of fully ensuring the running time of the compressor.

When drilling wells in a productive formation being penetrated, hydrostatic bottomhole pressure when it rises above the formation pressure may cause absorption of the drilling fluid by the formation, and when the formation pressure rises above the bottomhole pressure created by the mud column, then fluids enter the well and this can create a blowout, i.e. a manifestation; and absorption and manifestation are accidents.
Losses of the solution result in a decrease in hydrostatic pressure on the well wall in the upper part of the well body, cleaning occurs and favorable business is formed, including the violation of the zone around the well body; which lead to the extraction of the drilling tool and its sticking; therefore, in order to eliminate loss, it is necessary to reduce the density of the drilling fluid, if possible, and increase the value of the structural viscosity. Most accidents occur when drilling clayey rocks.
To reduce the adhesion of clay cake on the well wall, special chemicals are added to the solution: CMAD-1, graphite, oil, sulfonol, OП-10, CAM, soapstock tar (ST).
The narrowing of the well body occurs as a result of swelling of the clay layers.
To prevent complications and accidents associated with the drill string, they are systematically pressure tested. Test pressure values for different depths are shown.
To eliminate accidents associated with the drill bit, it cannot be kept at the bottom of the well for a long time.
The article presents the formulas:
- to determine the maximum speed of descent of the drilling tool.
- to determine the density of the solution.
- to determine the minimum stock of drilling fluid
The wellhead is equipped with appropriate preventers .
