Description
Technical field:
The utility model relates to a kind of oil well electric ignition tubing string that is used for the viscous crude heating exploitation, and particularly a kind of fireflood does not have cable formula electric ignition tubing string.
Background technology:
There is more than 80 heavy oil block implementing the combustion drive exploitation at present in the world.First link that starts the combustion drive exploitation is to light oil reservoir; Have only oil reservoir is successfully lighted; And the back oil reservoir that ignites gets into the high-temp combustion state immediately; Just can see desirable combustion drive effect, the combustion drive project just can continue, so high temperature dot fuel oil layer is the key problem in technology of combustion drive.The igniting tubing string that can realize high temperature dot fuel oil layer at present has two big types, i.e. natural gas downhole burner igniting tubing string and downhole electric heater igniting tubing string.Natural gas downhole burner igniting tubing string execute-in-place control technology difficulty is big; Operation has slightly improperly promptly the pit shaft explosion accident possibly take place; Explode and to cause when serious oil well to be scrapped or cause people's injures and deaths; A lot of combustion drives scene is arranged with the natural gas case of oil reservoir generation well shooting of igniting both at home and abroad, so is using in the baked wheaten cake oil field of having only minority to grasp this technology.Downhole electric heater firing technique comparative maturity, it is to be sent to downhole electric heater to electric energy, downhole electric heater is thermal power transfer that the heat energy of temperature up to hundreds of degrees centigrade removes the oil reservoir that ignites.The at present domestic downhole electric heater igniting tubing string of seeing has two class formations: one type is that cable and electric heater are fixed on the tubular column structure on the tubing string, and this kind tubular column structure adopts the three-phase electricity heat pipe to generate heat, and good reliability, power are big; Firing temperature is high, and the duration of ignition is short, and igniter exit flow temperature can detect; Ignition parameter is controlled easily; Can artificially adjust firing temperature more than oil reservoir high-temp combustion temperature, ignition success rate is high, is to generally believe ripe ignition process at present.But this technology also exists following deficiency: the one, and the three-phase power cable is bundled in the down-hole with oil pipe, can only disposablely use igniting expense high (cable cost account for disposable use equipment manufacturing cost 2/3); The 2nd, igniter central tube latus rectum only has 32 millimeters of Φ, and the later stage can't be lowered to the test that instrument carries out aspects such as temperature and pressure.Another kind of downhole electric heater igniting tubing string is that cable and electric heater can propose reusable tubular column structure.This kind tubular column structure is in oil pipe, to be lowered into down-hole enforcement igniting with the single-phase cable suspention of wire armoring minor diameter electric igniter, but should technology also have following shortcoming: the one, and single-phase cable power supply reliability is poor, in case single-phase cable goes wrong then counts out; The 2nd, the power of electric igniter is less than the power of fixed electric igniter, and the oil reservoir time of igniting is long; The 3rd, the temperature that when igniting can not test point firearm exit flow only can be removed ignition parameter and judge the oil reservoir ignition conditions with the input electrical quantity indirectly, and error is bigger; The 4th, igniter length is big, is lowered to and to trip out task difficulty big.Because this technology is only passed through ground experiment, also do not get into down-hole actual ignition test, at present, this method does not also have in the oil field actual successful example of lighting a bite fireflood well.
The utility model content:
The technical problem that the utility model will solve provides a kind of fireflood does not have cable formula electric ignition tubing string; This electric ignition tubing string has been realized no cable formula conduction, has practiced thrift expensive power cable acquisition expenses, has significantly reduced oil reservoir igniting cost; It is big to have the electric igniter heating power simultaneously; Temperature is high, regulate and control easy intuitively, the reliable advantage of system.Overcome existing igniting tubing string and adopted power cable transmission electric weight igniting expense high, can't be lowered to the deficiency that instrument carries out the test of aspects such as temperature and pressure.
The technical scheme that the utility model is taked is: a kind of fireflood does not have cable formula electric ignition tubing string, comprises switch board, oil pipe, down-hole electric igniter and horn mouth; Oil pipe short circuit lower end connects the insulation short circuit, and insulation short circuit lower end connects oil pipe, on the oil pipe below the insulation short circuit down-hole electric wire connecting junction is installed; The cable seal device is equipped with in the sleeve gate II outside, and the firewire cable of being drawn by switch board is passed the cable seal device and is connected with the down-hole electric wire connecting junction; Root oil pipe bottom, end is connected with the interior pipe of the electric igniter of down-hole electric igniter; Insulation isolation-conductor is installed in electric igniter upper end, down-hole and contacts with sleeve pipe; Pipe connects the heater element arrival end through conductive plate in the electric igniter, and the heater element port of export is connected with insulation isolation-conductor; Sleeve pipe upper end splicing sleeve flange, casing flange is connected with switch board through the zero line cable; Block ring is equipped with in electric igniter lower end, down-hole, and horn mouth is equipped with in electric igniter bottom, down-hole; The suspension sealer is equipped with in test strobe upper end, and measuring temp. wire cable passes the suspension sealer, and temperature probe is connected the measuring temp. wire cable lower end, with measuring temp. wire cable in oil pipe, be lowered into bell-mouthed below.
All be set with the insulation centralizer on the every oil pipe.
The beneficial effect of the utility model is: the utility model has been owing to adopted unique no cable formula electrically conducting manner, thereby practiced thrift expensive power cable acquisition expenses, can significantly reduce oil reservoir igniting cost.It is big to have the electric igniter heating power simultaneously, and temperature is high, regulate and control easy intuitively, the reliable advantage of system.
