R.Ya. Abdyukova, N.I. Bagautdinov, A.N. Zotov. Modelling of valve plate impact in its landing to the seat in drill pump . Electronic scientific journal "Oil and Gas Business", 2012, Issue 2, pp. 52-65. http://www.ogbus.ru/authors/Abdyukova/Abdyukova_2.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. The carried out calculations have shown that application of an elastic element will lead repeated (in tens times) to decrease in the impact efforts transferred to the case of the pump. 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

 Existing methods of drilling at application of the most perfect technics and the control of wells not always provide safe conducting works. Blowouts result from uncontrolled kicks, hence – it is incumbent on all persons directly concerned with drilling operations to understand kicks, their causes, modes and basic means of closing them.

Attempt of the description of thermal influence's process, assuming heating of the heat-carrier, evaporation of water and heat transfer to clutch coupling of tubing, using the theory of similarity and dimensions is carried out in work. The modeling relations, allowing to predict dependence of efficiency of thermal influence's process, so-called “thermal breaker” from influence parameters (a quantity of water in the evaporator, endurance time etc.) and parameters of influence object (wall thickness and clutch diameter etc.) are received for design developed by authors. The received dimensionless complexes allow extending the established laws on wide dimensional tubing family.
Keywords: tubing, thermal influence, threading, similarity and dimensional method

 In the given article problems of influence of saturation fluid type on mechanical strength of Priobskoe oil field core samples are examined. Common characteristics of the deposit are given and reasons of wide application of fracturing treatment are explained. Some factors that influence on permeability and porosity of reservoir are shown. In particular results of studying of rock pressure influence on reservoir properties is given. Moreover in the article results of monoaxial compression experiments of core samples that were saturated by fresh and mineralized water, hydrocarbons and water solutions of water-repellent NG-1 are shown. It was revealed that these solutions lower the mechanical strength of samples and reasons of such results are explained.

 The results of investigations in 2006-2010 for oil, gas and gas hydrates on the Antarctic Peninsula continental margin are given. In 2004 and 2006, the marine geoelectric researches by methods of forming a short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS) had been conducted in this region.
The "deposit" type anomaly was mapped by FSPEF survey, and anomalous polarized layers of "hydrocarbon deposit" type were chosen by VERS sounding within this anomaly on Antarctic margin in the region of UAS "Academician Vernadsky". Anomalous zones of "gas hydrate deposit" type were detected on the South Shetland margin due the special technology of satellite data processing and interpretation using. These results confirm the high gas hydrates potential of the West Antarctic region. Some practical results of the experimental approbation of these original technologies for the "direct" prospecting and exploration of hydrocarbon (HC) and gas hydrates accumulations in different oil and gas bearing basins of Russia and Gulf of Mexico are proposed. The integration of satellite data processing and materials of FSPEF-VERS methods enable to improve their efficiency for different geological and geophysical
problems solving.
Keywords: Antarctic margin, gas hydrates, hydrocarbon deposits, geoelectric methods, satellite data, direct prospecting
