R.Ya. Abdukova. Vibroinsulation of the valve seat for drill pump. Electronic scientific journal "Oil and Gas Business", 2011, Issue 5, pp. 243-253. http://www.ogbus.ru/authors/Abdyukova/Abdyukova_1.pdf ![]()
The article is devoted to vibroinsulation of the valve seat for drill pump. It is offered to establish the elastic element between valve seat and pump casing. Calculations showed that the use of an elastic element will lead to multiple (dozens of times) reduction impact efforts transmitted to the pump casing. It is established that Young's modulus and height of elastic element are basically act on the module of the efforts transferred to the case of the pump and their frequencies during landing plate on the valve seat. Thus decreasing of frequency of the efforts passed on the body of the drill pump during plate’s landing does not lead to the resonant phenomena in the pump.
Keywords: flush pump valve, vibration isolation, bench test of the pump, natural frequencies, resonance

The results of the development of energy-efficient means and methods for suppressing activity of bacteria in the process liquids at the oil production. As a means to control planktonic sulfate-reducing bacteria species was developed a device for a magneto hydrodynamic treatment the produced water. Device provide simultaneous effect on bacterial cells by the centrifugal force and electric currents induced in magnetic field. There have been laboratory and field tests, which showed complete inhibition of activity of planktonic cells of anaerobic bacteria. The methods of calculation and design of device were developed. To suppress the activity adhered forms of sulfate-reducing bacteria has developed a system of magneto hydrodynamic treatment of produced water with simultaneous dosing of calcium ions, which leads to the binding of sulfate ions in the soluble ions of calcium sulfate. This leads to a decrease in the concentration of sulfate ions below 0.05 per cent by weight. And, consequently, to suppress the activity of bacteria adhered. The methods of calculation and design of biocide devices, conducted laboratory and field tests showed a reduction in the number of corrosive lesions of bio corrosion ten times..

A new method for increasing the efficiency of oil production chemicals - corrosion inhibitors and demulsifying agents based on the use of reagents with the input node of the magneto hydrodynamic treatment. With this input to the layer of reagent dispensed is an influence of moving flow of ions hydronium, which reacts with the reagent molecules and change their adsorption and surface-active properties. Using this method allows to increase the effectiveness of corrosion inhibitors up to 17 per cent, and demulsifying agents to 20 per cent. Applications of this reagent dosing method reduce the number of agents by 15-20 per cent and thereby reduce the cost of mining and preparation of oil and water emulsions.
