Abstract
The invention provides a novel petroleum perforating charge, aiming to provide a novel perforating apparatus for a petroleum perforating technology so as to achieve an effect of increasing penetration depth and aperture of the perforation. The novel petroleum perforating charge of the invention comprises a yam-like mantle, an explosive and a shell, wherein the yam-like mantle is in a cylindrical shape, an upper top surface and a side surface of the cylinder have an included angle of 90 degrees, and the cylinder has a height of H1 and a diameter of D1; the interior of the shell is a cavity structure, the interior cavity has a height of H2 and a diameter of D2, the explosive is filled in the cavity, an explosive filling aperture is D3 while the height is H3, and the size of the interior cavity matches with that of the yam-like mantle; the shell has a diameter of D4 and a height of H4, upper and lower bottoms of the shell are d2 thick, a sinking circular ring is H5 high, internal and external radiuses are respectively D2 and D1, a conical explosive filling bottom surface circle removed on the top of the centre of the shell has a diameter of D2, a bus and the bottom surface have an included angle of theta, and the diameter of the bottom surface is as same as that of the yam-like mantle; and an explosive 8701 is selected as the explosive of the petroleum perforating charge.
Description
Technical field
The present invention relates to the engineering explosion technical field, specifically is a kind of novel petroleum perforation charge that is used for oil exploitation.
Technical background
In the oil exploitation process, it is the biggest factor that influences the WFI ratio deeply that perforation is worn, under the desirable condition of storage of non-homogeneous geology or under the production status, eye diameter and eyelet cleannes also are the key factors that influences productivity ratio.At present, the kind of China's perforating bullet development is single, is difficult to adapt to complicated down-hole oil storage geological conditions.
Summary of the invention
The present invention seeks to the petroleum perforation technology provides a kind of new perforation equipment, to reach the effect of wearing dark and aperture that improves perforation.
The present invention includes cavity liner, explosive, housing.Cavity liner is a drum shape, and the last end face and the side angle of bucket are 90 °, and bucket is high to be H

1Enclosure interior is a cavity structure, and the internal cavities height is H
2, cavity diameter is D
2, explosive is contained in the cavity, and the powder charge bore is D
3, highly be H
3, the internal cavities size cooperates with cavity liner; Diameter of the housing D
4, height H
4, housing is base thickness d up and down
2, sinking annulus height H
5, interior outer radius is respectively D
2And D
1, the bottom surface circular diameter D of the conical powder charge that remove at top, housing center
2, the angle of bus and bottom surface is θ, the bottom surface diameter is identical with the cavity liner diameter; The explosive of petroleum perforation charge is selected 8701 explosives for use.
The cavity liner of this invention is a drum shape cavity liner, makes cavity liner form coherent jet under the detonation wave loading environment by adjusting charge constitution.Detonation mode is that ring detonates or multipoint priming on the powder charge top end face rib, after the charge detonates, crush simultaneously along normal direction simultaneously in the last end face of drum shape cavity liner and side, at the initial jet of the cornerwise formation annular of the central cross-section of cavity liner, this annular jet mouth diameters increase in time reduces gradually, when arriving just the cavity liner axis, annular jet converges once more and forms a coherent jet, thereby realizes the purpose of perforation.
The invention has the beneficial effects as follows: compare with existing perforating bullet, the present invention can improve the power of perforating bullet when reducing shot elevation effectively, promptly increase perforating depth and diameter, has a wide range of applications.
