Abstract
The utility model relates to a production-increasing device of an oil-well of loosening rock by the dilatancy of explosive waves, belonging to the special production-increasing technology field of oil production and ground layer adaptation. The utility model comprises a charge column 1, a center tube 2, a sealed cavity 4, a plug 6, an igniter 8 and the like, wherein the column 1 is arranged on the center tube 2, the center tube 2 is connected with a sub 3 to form the sealed cavity 4, the plug 6 is provided inside the sealed cavity 4, a section 5 is formed by the sealed cavity 4 and the plug 6, a blasting cap 10 is connected with a cable head 9. The range which the utility model acts on the sandstone ground layer can reach 6-8 meters, and the range that the utility model acts on the limestone ground layer can reach 10 meters. The depth of the dealt oil layer can reach between 2500 meters and 5000 meters. The increase production of the oil-well can reach by 4-6 times, the increase production can reach by more than 20 times, the depth of the dealt water layer can reach between 100-3500meters, the liquid level is averagely increased by 2.5-4.5times, and the average effective date is 2-3 years.
Description
The utility model relates to oil development, the extraordinary yield-increasing technology of class is transformed on the stratum, specifically, is the bloated loosening oil well production increasing device of a kind of pressure.
At present, external to gunpowder, explosive in the application aspect the well production increment, a large amount of indoor and outdoor experiment, mechanism research and The field have been carried out, domesticly also studying, developing at present, form syllogic powder charge, first shell bullet, the shell bullet has been arranged, crossed series of formed technology and auxiliary products such as oil pipe Pressure breaking bullet, perforating and fracturing are compound, blind-hole type composite gun perforation, oversleeve type composite gun perforation, liquid medicine yield-increasing technology, but mainly concentrated on the application facet of gunpowder.
The purpose of this utility model is to provide a kind of whole the becoming flexible of the rock of nearly well band is formed a loosening belt, promptly is a microcrack band, the loosening oil well production increasing device but not the pressure of one or two simple main seam expands.
The utility model is achieved in that including powder column 1, central tube 2, pipe nipple 3, annular seal space 4, a joint 5, stopper 6, igniter 8, cable head 9, blasting cap 10, plug 11, cable 12 powder columns 1 is contained on the central tube 2, central tube 2 is connected to each other with pipe nipple 3 and forms annular seal space 4, stopper 6 is arranged in the annular seal space 4, annular seal space 4 forms a joint 5 with stopper 6, blasting cap 10 is connected with cable head 9, cable head 9, logging cable 12 are contained on one joint 5 of top, on one joint 5 of bottom plug 11 are housed.
The utility model also adopts following technical scheme:
Igniter 8 is contained in the central tube 2, and powder column 1 links to each other with central tube 2 by pipe nipple 3, constitutes every joint 7.
Every joint 7 is equipped with igniter 8, powder column 1
Stopper 6 is divided into annular seal space 4 more than two joints.
Igniter 8 can be one, also can be more than one.
Advantage of the present utility model is can reach 6～8 meters to the sphere of action of sandstone formation, can reach 10 meters to limestone, the handling oil layer depth can be at 2500 meters between the 5000m, oil well production increasing can reach 4～6 times, surplus oil/gas well stimulation can reach 20 times, handle water depth from 100 meters to 3500 meters, liquid level on average increases by 2.5～4.5 times, and the average effective phase is 2～3 years.
Mainly be the stack that utilizes blast wave, the strictness control by time-delay mechanism effectively superposes blast wave; the mode of stack is in depths, stratum crest and crest stack; trough and trough stack cause rock that the condition of phenomenon that expands takes place to press, thereby strengthen action effect; loosening stratum; increasing oil and gas production, near the well place, is the stack of crest and trough; thereby reduce the power of blast, protective casing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a partial enlarged drawing of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
The ignition system of powder column 1 is contained in the annular seal space 4, the stopper 6 that wherein has ignition charge to make, and stopper 6 is divided into several joints 7 with annular seal space 4, and every joint is adorned 8, one powder columns 1 of an igniter at least, so every joint 7 all has an automatic ignition slot.The cable head 9 of band blasting cap 10 is contained on the uppermost joint 5, on one joint 5 of bottom plug 11 is housed.
Igniter 8 is contained in the central tube 2, with pipe nipple 3 powder column 1 is linked to each other with central tube 2 then, constitutes a joint 7, and every joint 7 usefulness stoppers 6 are connected to each other, and one joint dress cable head 9 links to each other with logging cable 12 in the top.
Handle assembly to well inside, provides electric current by logging cable 12 to blasting cap 10 down, and blasting cap 10 is lighted, and the point of ignition firearm 8 successively.
The comburant heating central tube 2 of each igniter 8 is ignited modification powder column 1, and process is carried out successively up to all completing combustion of powder column 1.
Ignite the composition that depends on stopper 6 time delay of next joint 7.
This technology is different from the general seam technology of making, and it is whole loosening the rock of nearly well band, forms a loosening belt, and it is a microcrack band, but not one or two simple main seam.
