Abstract
The utility model relates to a cable explosive integral cement column which is relevant to the down-hole plugging technology in the petroleum drilling aspect, and comprises a cable 1, a detonating cord 2, mortar 3, kill fluid 4, a cylinder 5 and a bridge plug 6, wherein, the upper end of the cylinder 5 arranged in a sleeve 7 is provided with the cable 1, and the inside of the cylinder 5 is provided with the mortar 3 and wound with the detonating cord 2. The kill fluid 4 is arranged between the cylinder 5 and the sleeve 7. The bottom of the utility model is provided with the bridge plug 6. The utility model avoids the technical problem that cement plug can not be formed by adopting a cable of a cement pouring cylinder to pour the cement when mortar density and mud density differ by little, and explodes off the disposable mortar cylinder in the explosive way to form a cement plug and reach the goal of plugging with mortar plug.
Description
Relate to the field
The utility model relates to a kind of oil drilling aspect that is used for, the whole gray columns of relevant down-hole blocking technology cable explosion type.
Background technology
At present, fall grey technology for what the sealing the subject of knowledge and the object of knowledge that guarantees bridging plug adopted, traditional method is to fall ash with the cable ash transporting cylinder, utilizes the formed pressure reduction of cement slurry density, and cement paste flows into pit shaft, forms the ash plug.And when cement slurry density and mud density were more or less the same, cement paste was difficult for flowing out, and can't form the ash plug, and the mode of the grey wound packages ash of this usefulness not only takies grey volume of slurry, and mortar is all flowed out.
Technology contents
The grey whole gray columns of cable explosion type that can't form the technical problem of ash plug of ash transporting cylinder cable when being to provide a kind of effective solution cement slurry density and mud density to be more or less the same, the purpose of this utility model is provided.
The utility model is achieved in that
Comprise cable 1, detonating fuse 2, mortar 3, well killing fluid 4, cylindrical shell 5, bridging plug 6, be built-in with cylindrical shell 5 at sleeve pipe 7, there is cable 1 upper end of cylindrical shell 5, mortar 3 is arranged in the cylindrical shell 5, and be tied with detonating fuse 2, and between cylindrical shell 5 and sleeve pipe 7, well killing fluid 4 is arranged, in the bottom of this device bridging plug 6 is arranged.
The utility model also adopts following technical characterictic:
Advantage of the present utility model is:
Adopt the grey technical problem that can't form the ash plug of ash transporting cylinder cable when having avoided cement slurry density and mud density to be more or less the same, adopt the blast mode disposable ash tube cylindrical shell of scraping, form cement plug, reach the purpose of ash plug shutoff, in the plugging technology of petroleum exploration and development down-hole.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Concrete enforcement
The utility model mainly is made up of cable 1, detonating fuse 2, mortar 3, well killing fluid 4, cylindrical shell 5, bridging plug 6, be built-in with cylindrical shell 5 at sleeve pipe 7, there is cable 1 upper end of cylindrical shell 5, mortar 3 is arranged in the cylindrical shell 5, and be tied with detonating fuse 2, with well killing fluid 4 is arranged at cylindrical shell 5 with sleeve pipe 7, in the bottom of this device bridging plug 6 is arranged, adopt disposable cylindrical shell 5, twine cylindrical shell 5, will fill the cylindrical shell 5 of mortar 3 after desired depth with detonating fuse 2, detonating fuse 2 is ignited in the ground energising, the cylindrical shell 5 of scraping forms gray columns, reaches the purpose of ash plug shutoff.
