Abstract
The utility model relates to a multi-pulse composite perforator which belongs to the technical field of design and manufacturing of a composite perforator for an oil gas well. The multi-pulse composite perforator consists of a perforating gun and a perforating charge. An energetic material block is arranged in a front bin cover. Both sides of the perforating charge are respectively provided with an energetic material box. The using method of the product is that the multi-pulse composite perforator is arranged in the oil gas well deeply, and the perforating charge is detonated by a detonating fuse, so that an oil well casing and a ground layer are perforated. When the perforating charge is detonated, the energetic material block and energetic materials in the energetic material boxes are burnt. Owing to different burning speeds of the energetic materials, the multi-pulse composite perforator can realize primary and secondary dredging and fracturing for a perforating pore duct and the ground layer, so that the perforating pore and the ground layer can be effectively dredged, the depth and the aperture of the perforating pore are increased to a certain extent, and more oil and gas in the ground layer can enter the oil well along the perforating pore. The multi-pulse composite perforator has the advantages that the output of the oil and gas can be effectively improved, the structure is simple, and the design is reasonable.
Description
Technical field
The utility model belongs to design and the manufacturing technology field of oil gas well with composite perforator.
Background technology
Perforator is the special-purpose explosive that is used for punching oil well casing, cement and part stratum in the petroleum industry.Load perforating bullet at perforating gun during use, go deep into the oil gas down-hole.The perforating bullet blast punctures oil well casing and stratum, and the oil and natural gas in the stratum can be entered by the duct that perforating bullet is got in the oil gas well, so that exploitation.And existing perforator is because on structure design, the effect of blast back perforation is not really desirable.Can not effectively dredge and pressure break perforation and stratum, it is limited to make that oil gas in the stratum enters the amount of oil gas well, directly influences oil and gas production.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind ofly can be effectively dredges composite perforator with pressure break to perforation and stratum, to solve the problem that existing product exists.Improve oil and gas production.
Structure of the present utility model is as shown in drawings: be made of perforating gun and perforating bullet.In perforating gun, have the perforation firing mount.On the perforation firing mount, perforating bullet is housed.Cang Gai before the perforating bullet bottom has one.In the lid of preceding storehouse, have the energetic material piece.Have the energetic material box in the both sides of perforating bullet.Have energetic material in the energetic material box.
Using method of the present utility model is: after it is goed deep into locating in the oil gas well, ignite perforating bullet by detonating fuse, explosive charge in the perforating bullet penetrates sleeve pipe and stratum.When perforating bullet detonated, the energetic material in energetic material piece and the energetic material box took fire.Determine under the swabbing action of the parital vacuum that the jet afterbody forms by the unburned energetic material of high energy gas Buddhist monk that the energetic material piece burning faster of combustion speed produces, trail jet and enter in the perforation road, realize the pressure break first time perforation tunnel and stratum.Material combustion in the energetic material box thereupon, the annular space of the high energy gas of generation in pit shaft forms a high pressure gas tagma, those still unburned energetic material pieces that ignite, the air-flow of generation enters perforation tunnel and stratum, carries out the pressure break second time.Make that perforation and stratum are effectively dredged, strengthened perforating depth and aperture to a certain extent, making to have more oil gas to enter in the oil well along perforation in the stratum.Improve the output of oil gas effectively.The utility model is simple in structure, and is reasonable in design.Owing in the preceding storehouse of perforating bullet, have the energetic material box of energetic material piece and body both sides, make perforation can access the echelon pressure break.Help the raising of oil and gas production.
