' 6 Claims. (Cl. 166-38) The invention relates to the production of petroleum and pertains more particularly to a process for igniting oil, oil residue or other combustible materials presentin an oil-bearing formation in the production of petroleum by means of underground combustion.
It has previously been proposed to produce oil by the use of underground combustion. In this method a part of the oil originally present in the oil-bearing formation is burnt. To this end, the oil is ignited in or through one or more wells, the combustion of the oil being subsequently maintained by forcing in air and attempting to produce the unburnt portion of oil from one or more (the same or other) wells.
Various methods are known for igniting oil, oil residue, tarry substances, etc. present in the formation. To this end, highly heated gases are usually introduced in a well and forced into the formation. It has also been proposed to ignite the oil by means of an electric current or thermite bombs. It ,is, however, difl'icult to obtain a uniform combustion of the oil in the formation by these methods. Furthermore, there is a considerable risk of the formation being clogged by deposits of solid combustion products and as a result of sintering caused by the very high temperatures which occur.
It is therefore an object of the present invention to provide a method of ignition which ensures a uniform combustion of the oil in the formation surrounding a well, without the formation being clogged by deposits or sintering, since in this method the temperature does not increase to such an extent that there is any possibility of the formation sintering.
According to the invention the combustible material (oil, oil residue, tar, etc.) in an oil-bearing formation is brought to the high temperature required for combustion by introducing into a well and contacting the oil-bearing formation therein with a liquid which oxidizes relatively easily, together with, or followed by, a gaseous oxidant which under the operating conditions reacts spontaneously with the liquid.
A part of the combustible material present in the formation, usually oil, may have collected in one or more wells which lead into the formation. Accordingly, the oil (oil residue, etc.) present in the wells also belongs to the combustible material which can be ignited according to the invention.
Although the desired result can often be obtained by introducing the liquid into a well, it is advisable, in some areas, to force the liquid into the formation itself. The gaseous oxidant reacts with the oxidizable liquid, developing a high degree of heat, as a result of which the heat required for ignition is developed at the very place (the bottom of the well and in the formation itself) where it is required for the underground combustion which then follows. By forcing air into the formation afterwards, a uniform combustion of the oil surrounding the well can be readily obtained.
In any case the relatively easily oxidizable liquid should be more readily oxidizable" than the combustible material in the formation (measured under the same conditions),
The oxidizable liquid and the oxidant are chosen so that under the operating conditions (of pressure and temperature in the well. or the formation) there is a spou-- taneous reaction between these substances. It is advisable, however, to use a combination which reactsat even lower temperatures than those encountered in a well.
Suitable oxidizable liquids include: unsaturated aliphatic hydrocarbons, such 'as cracked distillates; cyclic hydrocarbons, such as turpentine, tetralin or decalin; unsaturated aliphatic or cyclic oxygen-containing compounds, such as croton-aldehyde,,allylalcohol, furfural or linseed oil; aliphatic or cyclic nitrogen-containing, com: pounds, such as ethylene diamine or anilineand phenylhydrazine. l
The liquid in question need not be a simple substance, but may consist of a mixture of chemical compounds; moreover, it may comprise a reaction initiator, such as peroxide, or a catalyst, such as manganese resinate. The liquid may also be a suspension or an emulsion.
The gaseous oxidantshould be so chosen that, at least under the operating conditions of pressure and temperature in the well or the formation, it reacts spontaneously with the liquid. Suitable substances include oxygen,
ozone, gaseous nitrogen oxides, gases containing a.relatively high concentration of such oxidants, and mixtures of such. gases. Occasionally (depending on the liquid and operating conditions used) ordinary air may also be .used, generally under high pressure.
Air is generally used for, maintaining the actual com: bustion of the oil. in the formation, which thus follows the ignition. If desired, this air may contain an in,- creased or reduced oxygen content. Air with a reduced oxygen content may be obtained by mixing it with inert gases.
If the formation contains a relatively large amount of water, it is often advantageous first to expel the water from the neighborhood of the well, for example, by using a gas drive since the water is more readily displaced than the more viscous oil.
If it is desired to initiate an underground combustion in a formation where a high temperature and/or a high pressure prevails naturally (viz. usually in a deep formation) the readily oxidizable liquid may sometimes be omitted altogether, provided a gas is chosen as the oxidant which contains a very high concentration of oxygen (preferably pure or substantially pure oxygen), if desired, together with a gaseous catalyst: or reaction initiator such as ozone or N0 The gaseous oxidant may, for example, first be passed through an ozonizer which may, for example, be provided in the well. The pressure at which the oxidant is introduced. may be 25- atm. or even higher.
After the temperature required for igniting the oil is reached, ordinary air may be injected instead of the said gaseous oxidant.
