Abstract
The invention belongs to the field of petroleum production, particularly relates to a shaped charge liner perforating bullet which comprises a casing (1), a charge (2), a metal powder shaped charge liner (3) and an initiation device (4), and mainly solves problems about increasing perforation depth and enlarging aperture. The shape of the casing comprises a circular truncated cone section (5) at the upper part and a cylindrical section (6) at the lower part; an inner cavity of the casing comprises four sequentially-connected sections, including a cylindrical explosion propagation hole (7), a hemispherical cavity (8), a circular truncated cone cavity (9) and a cylindrical cavity (10); the inner cavity of the casing is made of low-debris material; after the perforating bullet is exploded, the casing is broken into fine debris particles which can circulate and return to ground conveniently, and the hidden danger of well jamming is eliminated; and the metal powder shaped charge liner is formed through the combination of a horn-shaped upper liner body (11) and a large-cone-angle lower linear body (12), the connection is smooth due to no joint point, the metal powder shaped charge liner is made through a composition metal powder formula preferably, and the initiation manner refers to initiation at the center of the top end surface on the charge.
Description
Technical field:
The invention belongs to the Petroleum Production field, be specifically related to a kind of cavity liner perforating bullet.
Background technology:
Along with the further exploration and development in oil field, height is worn dark large aperture perforating bullet and more and more is much accounted of.On the one hand, it is the biggest factor that influences the WFI ratio deeply that perforation is worn, and improves perforation and wears deeply, and particularly making it to pass the completion contaminated area is the most important means that improve the WFI ratio.On the other hand, 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.The research of perforating bullet at present should be that no pestle is stifled, height is worn deeply, Gao Kongmi and large aperture perforating bullet, but these characteristics are gathered the whole body and also are difficult to.
Summary of the invention:
The technical problem that the present invention will solve is: deep penetrating charge and large aperture perforating bullet can not form large aperture and the deep penetration problem on oil gas well stratum on the sleeve pipe simultaneously.
Technical scheme of the present invention is: the cavity liner perforating bullet is made up of housing, powder charge, cavity liner and priming device; The housing profile is made up of top round platform section and lower cylindrical section, and the housing inner chamber is joined successively for four sections by cylindrical propagation of explosion hole, hemisphere chamber, round platform chamber and cylindrical cavity and forms; Cavity liner combines the smooth connection of contactless by tubaeform upper outlet body and big cone angle lower cover.Detonation mode is to detonate in powder charge top end face center, and the cavity liner perforating bullet adopts the shell case inner-cavity structure of combination, to improve the effective charge amount; Adopt the low-debris material to process, after the perforating bullet blast, housing cracks into tiny detrital grain; Be beneficial to circulation and return ground, eliminated the hidden danger of Ka Jing, after the charge detonates; The upper outlet body of cavity liner forms high-speed jet and flies to perforating bullet perforation end face, height is carried out on oil gas well stratum wear dark penetration, the jet that the lower cover of cavity liner (12) forms; Sleeve pipe is carried out the large aperture penetrate, carry out the relay perforation then, realize the purpose of perforation.
The invention has the beneficial effects as follows: the powdered metal liner that adopts this structure; Make the bus of cavity liner become the combination of tubaeform curve and broken line; Under the constant situation of cavity liner height and opening, bus length improves greatly, thereby has improved the penetration depth and the piercing aperture of perforating bullet.
