Oil and Gas Exploration
The most important scientific and technical problem in the field of field development is the most complete extraction of oil from the subsurface while ensuring high rates of development. The solution of this problem is complicated by the fact that most of the oil fields in the Western region of the Republic of Kazakhstan have moved to a late stage of development. At the deposits of the Mangystau region, the composition of borehole products includes resins, asphaltenes, paraffins, salts. All this leads to colmatation of bottom-hole zones of wells (CCD), a decrease in the pick-up rate of injection wells, a decrease in the flow rates of producing wells. New progressive methods of processing the bottomhole zone include methods of shock-wave action on productive rock strata. The purpose of the PFT shock wave processing (SWP) of wells is to restore and increase the pick-up of injection wells in combination with the use of chemical compositions, as well as to intensify oil production at surrounding producing wells. The SWR was carried out at 10 injection wells of the fields of JSC "Ozenmunaigas". For each injection well, groups of producing reacting wells (cells) were identified, for which the effect was calculated according to the methods. According to the results of the PFT (pilot field tests), the technological effect (increase in pick-up) was obtained at 6 injection wells and the effect of additional production was achieved at 5 cells of reacting producing wells. The success rate of the technology was 50%.
