Abstract
The utility model relates to an inner blind hole multi-level energy accumulation burning composite perforator which mainly solves the problem that an existing perforator adopts a type of burning powder, and is characterized in that: a multi-level energy accumulation burning powder box (6) is arranged outside the right side of a perforating bullet (1), a conical hole is arranged in the multi-level energy accumulation burning powder box (6) and multi-level energy accumulation burning powder is arranged on the periphery of the inner wall of the conical hole. The inner blind hole multi-level energy accumulation burning composite perforator has the characteristics of multi-level energy accumulation, delayed burning, pore path supporting and convenience in continuous shooting.
Description
Technical field
The utility model relates to the required perforator of oil field oil recovery field perforating job, the multistage cumulative burning of especially interior blind hole composite perforator.
Background technology
In oil recovery field, oil field, oil well needs to carry out earlier perforating job before oil recovery.During perforating job, perforating bullet need be fixed in the perforator the interior blind hole on perforating bullet and the corresponding perforator.Conventional composite perforator all adopts a kind of burning medicine, and architectural feature is that the powder charge center is a cylindrical hole.This powder charge exists igniting insufficient, incomplete combustion, and action time is short, and the problem that the gas flow of generation is few is difficult to give full play to the effect of composite perforator ammunition, directly influences the oil gas well capacity.
Summary of the invention
In order to solve the problem that existing perforator adopts a kind of medicine that burns.The utility model provides the multistage cumulative burning of a kind of interior blind hole composite perforator.The multistage cumulative burning of blind hole composite perforator has multistage cumulative, time-delay burning, support duct, connects big gun characteristics easily in being somebody's turn to do.
The technical solution of the utility model is: multistage cumulative burning of blind hole composite perforator comprises firing mount and perforating bullet in the perforating gun in this.The perforating bullet right side is externally connected with multistage cumulative burning medicine box, in the multistage cumulative burning medicine box taper hole is arranged, and the taper hole inner peripheral wall has multistage cumulative burning medicine.
Multistage cumulative burning medicine in the such scheme is followed successively by from right to left and supports burning medicine, main burning medicine, delay powder and ignition charge; The outer multistage cumulative burning medicine box left end of perforating bullet is connected with positioning sleeve, and additional medicine piece is housed in the positioning sleeve; Firing mount has helicla flute outward, and the detonating fuse of perforating bullet is drawn through helicla flute.
The utlity model has following beneficial effect: the multistage cumulative burning composite perforator of blind hole in this is owing to adopt special positioning sleeve and multistage cumulative burning medicine box assembling perforating bullet, multistage cumulative burning medicine box is according to the cumulative principle, with the powder charge center cylindrical hole, be designed to internal taper hole.Multistage cumulative burning medicine box adopts multistage cumulative burning powder charge, and in compound medicine, add an amount of high temperature resistant proppant, two sides at perforating bullet add charge blocks, further increase detonation pressure, and then making igniting fully, completing combustion prolongs action time, the gas flow that produces increases, and makes quantity, length and the flow conductivity of formation fracture obtain volume raising significantly.The multistage cumulative burning of blind hole composite perforator has multistage cumulative, time-delay burning, support duct, connects big gun characteristics easily in being somebody's turn to do thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-perforating bullet among the figure, the 2-perforating gun, the 3-firing mount, 4-adds the medicine piece, the 5-positioning sleeve, the multistage cumulative of 6-burning medicine box, 7-supports the burning medicine, 8-master's medicine that burns, 9-delay powder, 10-ignition charge.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, multistage cumulative burning of blind hole composite perforator comprises firing mount 3 and perforating bullet 1 in the perforating gun 2 in this.Be socketed with multistage cumulative burning medicine box 6 outside perforating bullet 1 right side, in the multistage cumulative burning medicine box 6 taper hole is arranged, the taper hole inner peripheral wall has multistage cumulative burning medicine, and multistage cumulative burning medicine is followed successively by from right to left and supports burning medicine 7, main burning medicine 8, delay powder 9 and ignition charge 10.Outer multistage cumulative burning medicine box 6 left ends of perforating bullet 1 also are socketed with positioning sleeve 5 with perforating bullet 1 and multistage cumulative burning medicine box 6, and additional medicine piece 4 is housed in the positioning sleeve 5.Firing mount 3 is outer helicla flute, and the detonating fuse of perforating bullet 1 is drawn through helicla flute, conveniently connects the big gun operation, improves operating efficiency greatly, has adopted large aperture firing mount 3, moves after making perforating bullet 1 integral body, increases the height of burst.
Owing to adopt multi-stage acceleration burning medicine, make the high increase of whole bullet, 3～5 millimeters, prolong the action time of burning, after the perforation tunnel forms, burning medicine and high-pressure gas are followed jet the stratum borehole are carried out the relay-type loading second time, adopt special positioning sleeve 5 and multistage cumulative burning medicine box 6 assembling perforating bullets 1, further increase detonation pressure.The secondary pressure that forms impacts and makes the perforation tunnel extend expansion forward with crack form, rock stratum under the effect of this pressure around the duct produces many cracks, meanwhile, and in compound medicine, add an amount of high temperature resistant proppant, proppant has guaranteed to press off the sustainability in crack, reduced the resistance that oil gas flows into, taked efficient thereby improve oil gas.
