Abstract
Description
Изобретение относится к взрывчатым материалам, используемым в горном деле, а конкретно к материалам, применяемым в скважинах с целью увеличения притоков из продуктивных пластов. The invention relates to explosive materials used in mining, and specifically to materials used in wells to increase inflows from reservoirs.
Термогазохимическая обработка (ТГХО) скважин является одним из способов интенсификации притоков и, в перспективе, повышения нефтеотдачи продуктивных пластов [1] В отечественной и мировой практике ТГХО проводится с использованием либо штатных порохов, смесевых топлив и изделий на их основе, либо с помощью составов, специально разработанных для этих целей. К числу таких специальных составов относятся, в частности, вязкие или маловязкие горюче-окислительные смеси, воспламеняемые в скважинах либо с помощью штатных пороховых генераторов и аккумуляторов давления либо самопроизвольно под действием внешних температурных воздействий пласта. Thermogasochemical treatment (THC) of wells is one of the methods of stimulating inflows and, in the long term, increasing oil recovery of productive formations [1] In domestic and world practice, TGC is carried out using either standard gunpowders, mixed fuels and products based on them, or using formulations, specially designed for these purposes. Such special formulations include, in particular, viscous or low-viscosity combustible-oxidative mixtures ignited in wells either using standard powder generators and pressure accumulators or spontaneously under the influence of external temperature influences of the formation.
Основными недостатками вязких горюче-окислительных составов являются следующие для закачки в скважину требуется высоконапорное заправочное оборудование; не обеспечивается должная пожаро- и взрывобезопасность работ из-за саморазогрева вязких жидкостей при продавливании через узкие каналы и щели. The main disadvantages of viscous combustible-oxidizing compositions are the following: high-pressure filling equipment is required for injection into the well; proper fire and explosion safety of the work is not ensured due to self-heating of viscous liquids when forcing through narrow channels and slots.
Маловязкий состав типа аммонийная селитра+вода+перекись водорода специального заправочного оборудования не требует, однако весьма опасен в пожарном отношении, поскольку термораспад перекиси водорода, в особенности в присутствии окислов железа, происходит самопроизвольно (или, иначе говоря, в несанкционированных режимах). A low-viscosity composition such as ammonium nitrate + water + hydrogen peroxide does not require special refueling equipment, but it is very dangerous in fire terms, since the thermal decomposition of hydrogen peroxide, especially in the presence of iron oxides, occurs spontaneously (or, in other words, in unauthorized modes).
От перечисленных недостатков свободен состав, принятый нами в качестве прототипа и содержащий окислитель нитрат аммония 52,7.61,2 мас. горючее фенол 4,3.5,4 мас. и растворитель воду (остальное). Этот состав является гомогенным раствором, то есть не требует специального заправочного оборудования для закачки в скважину и полностью пожаро- и взрывобезопасным, поскольку наличие воды порядка 30.40 мас. исключает возможность как самопроизвольного воспламенения, так и самораспространения пламени от любого, даже самого мощного источника поджига при внешних начальных давлениях ниже 12.14 МПа. The composition adopted by us as a prototype and containing an oxidizing agent, ammonium nitrate 52.7.61.2 wt. combustible phenol 4.3.5.4 wt. and solvent water (rest). This composition is a homogeneous solution, that is, it does not require special filling equipment for injection into the well and is completely fire and explosion proof, since the presence of water is about 30.40 wt. excludes the possibility of both spontaneous ignition and self-propagation of the flame from any, even the most powerful ignition source at external initial pressures below 12.14 MPa.
Главным и по существу единственным недостатком состава-прототипа является его токсичность, поскольку один из его компонентов фенол относится к группе кожно-нарывных ядов. В силу этого осложнена технология работ при изготовлении состава на месте его применения, при закачке состава в скважину и при выполнении заключительных операций (промывка и пропаривание оборудования, шлангов, насосно-компрессорных труб и т.д.). Кроме того не исключена опасность заражения местности и глубинных пластов фенолом, в особенности, в аварийных ситуациях (проливы при ведении работ на устье скважины, выплески, неполнота горения состава и т.п.). The main and essentially the only drawback of the composition of the prototype is its toxicity, since one of its components phenol belongs to the group of blistering poisons. Due to this, the technology of work is complicated in the manufacture of the composition at the place of its use, during the injection of the composition into the well and during the final operations (washing and steaming of equipment, hoses, tubing, etc.). In addition, the danger of contamination of the terrain and deep seams with phenol is not excluded, especially in emergency situations (spills during work at the wellhead, splashes, incomplete combustion of the composition, etc.).
Целью изобретения является разработка жидкого горюче-окислительного состава, содержащего нетоксичные компоненты и образующего нетоксичные продукты горения в интересах охраны труда и экологической защиты окружающей среды при ТГХО скважин. The aim of the invention is the development of a liquid combustible-oxidizing composition containing non-toxic components and forming non-toxic combustion products in the interests of labor protection and environmental protection during THC wells.
Поставленная цель достигается тем, что в известный состав, содержащий нитрат аммония и воду, вводится глицерин в качестве горючего при следующих соотношениях между компонентами мас. This goal is achieved by the fact that in the known composition containing ammonium nitrate and water, glycerol is introduced as fuel in the following ratios between the components wt.
Нитрат аммония 48.60%
Глицерин 8.12%
Вода Остальное.Ammonium Nitrate 48.60%
Glycerin 8.12%
Water The rest.
Применение глицерина в качестве горючего в подобных составах, как следует из анализа доступной авторам научно-технической и патентной литературы, неизвестно. The use of glycerol as a fuel in such formulations, as follows from the analysis of the scientific, technical and patent literature available to the authors, is unknown.
Для проверки возможности изготовления и работоспособности предлагаемого состава в указанных пределах соотношения между компонентами были изготовлены и испытаны опытные образцы (см. таблицу). To test the possibility of manufacturing and operability of the proposed composition within the specified limits, the ratios between the components were made and tested prototypes (see table).
Таким образом, с точки зрения взаимной растворимости компонентов в диапазоне температур То≥ + 20oC и обеспечения горючести состава приемлемым следует считать образцы NN 1, 3, 4 и 5; при То≥ + 10oC только составы NN 1, 3 и 5.Thus, from the point of view of the mutual solubility of the components in the temperature range T o ≥ + 20 o C and ensure the combustibility of the composition,
