Elements of mathematical models of thermobaric treatment of the bottomhole formation zone oil and gas wells

Abstract

Аннотация. Как известно, наиболее широкое применение на практике нашли, так называемые, пороховые генераторы давления (ПГД)-в корпусных генераторах давления горение порохового заряда (ПЗ) происходит в специальной стальной камере, изолированной от скважинной жидкости, в бескорпусных-непосредственно в последней.

"Development of Gas-Generator Chemical Cartridges Working in the Mode of Non-Explosive Destructive Mixture"

“…[8][9][10][11] Underground mass explosions can have a seismic effect on underground excavations with a long service life located outside of seismic sources and locate on the surface of an industrial and cultural purpose building [12][13][14][15] . One of the promising ways to ensure the absence of seismic fluctuations, the improvement of the ecology of the environment from the harmful effects of explosive gases and the protection of natural resources, the reduction in the cost of mining ore and the energy intensity of mining operations, and the increase in the safety of their maintenance, is the use of a non-explosive disintegrating mixture based on gas-generator chemical cartridges [16][17][18][19][20][21][22] . Non-explosive disrupting substance (NEDS) is a non-flammable powder, hermetically packaged, which can be stored for a long time.…”

Processing of the Bottomhole Zones of Oil Wells With Use of the Carbon Nanomaterials

“…[4][5][6][7] One of the efficient ways of increase oil recovery of the well is acid treatment of a bottomhole formation zone. 8,9 For example hydrochloric acid is used for processing of the layers composed of carbonaceous rocks and so-called mud acid (acid clay) is used as the chemical reagent for processing of layers from terrigenous rocks. [10][11][12] In this work the compositions on the basis of ammonium nitrate of grade B, a magnesium, aluminium, an epoxy resin and the nanostructured soot as the gas-generating composition of gas generator for processing of oil wells were studied.…”
