The utility model has the characteristics of simple structure, powerful is big etc. With rock stratum area of contact, can the maximize saving cost of development reservoir.
Description
Technical field
The utility model relates to a kind of downhole tool for conventional gas and oil, shale gas, coal-bed gas exploitation, is also applicable to horizontal bare hole well section and the matching used novel porous pressure break shower nozzle sliding bush apparatus of open hole packer.
Background technology
Horizontal well multistage pressure break completion technique is an efficient completion yield-increasing technology of rising in recent years.China's Low permeable oil and gas reservoirs complex structure, there is the problems such as hop count is few, inefficiency, core tool dependence on import in existing fracturing technique.Still there is many limitations in the fracturing sliding bush product of China's independent research: fracturing sliding bush efficiency is lower, with formation-engaging surfaces is long-pending narrower, seepage area is narrow and small.
Around the problems referred to above, in the urgent need to developing a kind of novel porous pressure break shower nozzle sliding bush apparatus being applicable to conventional gas and oil, coal seam oil gas, fine and close oil gas, shale oil gas, can realize carrying out effective pressure break to multistage horizontal bare hole well, and open multiple pressure break shower nozzle, hydraulic pressure impact pressure break shower nozzle is pressed close to rock layer surface and is carried out injection pressure break, installation position and the spread geometry of pressure break shower nozzle can be formulated completely according to the situation of user's request and reservoir to be developed simultaneously, greatly improve and rock stratum contact area and post-fracturing seepage area, significantly increase incipient crack quantity.
Summary of the invention
The purpose of this utility model is
:for the deficiencies in the prior art, accelerate the development of shale gas, coal bed gas multi-stage horizontal well fracturing technique, spy provide a kind of crush speed fast, with rock stratum contact area is large, flexibility is high, carry out multistage pressure break to horizontal well and increase substantially the novel porous pressure break shower nozzle sliding bush apparatus of pressure break efficiency.
For achieving the above object, the technical scheme that the utility model head it off is taked is: a kind of novel porous pressure break shower nozzle sliding bush apparatus, be made up of top connection, lower contact, shower nozzle post, tapered injection skull, pressure break shower nozzle, baffle plate, the first shear pin, fracturing sliding bush, it is characterized in that: tool body is provided with six installing holes, shower nozzle post is made up of tapered injection skull, pressure break shower nozzle, baffle plate, the first shear pin, lower contact endoporus has a step, fracturing sliding bush to be placed in device slidably, by step stop; Shower nozzle post is by threading path to being fixed in installing hole, and pressure break shower nozzle upper end is threaded with tapered injection skull and hangs on expandable in shower nozzle post, and there is the first shear pin baffle plate upper end, opens by pressure.
Compared with prior art, the beneficial effect had is the utility model: (1) crush speed is fast, and pressure break orientation is wide, can arrange pressure break nozzle position thus reach to maximize to play its effect according to actual conditions; (2) pressure break shower nozzle can move back and forth and directly act on rock layer surface and reach maximization injection pressure break; (3) there is structure simple, applied widely, powerful, greatly improve with rock stratum contact area, maximize cost-saving with exploitation reservoir.

Detailed description of the invention
According to Fig. 1, shown in Fig. 2, the utility model porous pressure break shower nozzle sliding bush apparatus is by top connection 1, lower contact 10, shower nozzle post 3, tapered injection skull 4, pressure break shower nozzle 5, baffle plate 6, first shear pin 7, fracturing sliding bush 9 forms, body is provided with installing hole 2 and fixing by being threaded with shower nozzle post 3, baffle plate 6 is had in shower nozzle post 3, first shear pin 7, pressure break shower nozzle 5, tapered injection skull 4, pressure break shower nozzle 5 is linked together by screw thread and tapered injection skull 4, and hang in shower nozzle post 3, can radial direction move around, pressure break shower nozzle 5 lower end step stoppable is in shower nozzle post 3 upper end step, like this when baffle plate 6 is not opened, tapered injection skull 4 can allow pressure break shower nozzle 5 hang in shower nozzle post 3, after unlatching, 5, pressure break shower nozzle can not move out shower nozzle post 3, baffle plate 6 upper end is provided with the first shear pin 7 opened by pressure, without baffle plate 6 cannot be allowed under water pressures to cut off the first shear pin 7, namely pressure break shower nozzle 5 and tapered injection skull 4 cannot be opened, fracturing sliding bush 9 is placed in device, after putting into compound pitching 8, fracturing sliding bush 9 is cut off the second shear pin 12 between inwall and fracturing sliding bush 9 by pressure and then is slided, and be stopped at the step 11 of lower contact 10 endoporus.
Shown in Fig. 3, Fig. 4, pressure reaches a timing, after baffle plate 6 moves up and the first shear pin 7 is cut off, open pressure break shower nozzle 5 and tapered injection skull 4, under pressure, pressure break shower nozzle 5 and tapered injection skull 4 move up and treat that fracturing formations surface contact is sprayed, until produce crack.
