Accompanying drawing explanation
The structural representation of the protective casing protective casing sandblaster that Fig. 1 provides for the utility model embodiment.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model embodiment provides a kind of oil field compression fracture kit, especially a kind of sandblaster that is arranged on the protective casing on fracturing string.
Please refer to Fig. 1, the protective casing sandblaster that the utility model embodiment provides comprises the main body 1 being arranged on fracturing string and is fixed in the overcoat 3 outside main body 1.The axis of main body 1 is all parallel with the axis of fracturing string and sleeve pipe.Main body 1 along axis be provided with one run through its two ends cross aquaporin 11.Between overcoat 3 and main body 1, be formed with annular spray chamber 5, annular spray chamber 5 is communicated with mistake aquaporin 11.Overcoat 3 is provided with the injection channel 31 being communicated with annular spray chamber 5, and the center line of injection channel 31 is parallel with the axis of main body 1.
In fracturing process, high pressure enters annular spray chamber 5 containing sand flow body by main body 1 and is ejected in annular space by injection channel 31.Parallel with the axis of main body 1 because of the center line of injection channel 31, and the axis of main body 1 is all parallel with the axis of fracturing string and sleeve pipe.Therefore; the direction that high pressure ejects from injection channel 31 containing sand flow body is parallel with fracturing string and sleeve pipe, and high pressure slows down and fall afterwards again containing sand flow body in annular space, has avoided direct injection sheath; reduce sleeve pipe and be subject to high pressure to contain the damage that directly injection causes of sand flow body, protected sleeve pipe.
