Abstract
The utility model relates to a be used for reforming transform hydrocarbon reservoir in oil gas well production, the flowing back, lure a strong pulse gas energy fracturing unit who spouts, by tubular column 1, fracturing medicine 2, agree with into a 3, proppant 4, slow combustion medicine 5, tray 6 is constituteed, there is cable (or tubular column) 1 on the tray 6, there is an 3 of agreeing with into in the fracturing medicine 2, proppant 4, slow combustion medicine 5 is placed to the centre of fracturing medicine 2, adopt different performance when designing charge structure, different specifications, different burning speed's fracturing medicine, charge structure can realize great crest trough poor, repetitious strong pulse fracturing effect.
Description
Technical field
The utility model relates to a kind of technique device that is used to transform oil-gas Layer, discharge opeing, induced flow in the production of oil gas well, be used for oil oil gas well, well increasing yield and injection, being a kind of technology of strengthening the high enegry gas fracturing effect and carrying proppant, specifically, is flash gas energy pressure cracking device.
Background technology
The high energy gas powder charge device of Shi Yonging all is to use same specification, same performance, same charge constitution in the market, and the weak point of this method is:
1. form by cable (or tubing string), pressure break medicine, pallet, do not have contract to advance agent, proppant;
2. burning time is short
3.P---the t curve is the curve of a rising, the difference of crest and trough not obvious (Fig. 1)
4. after the pressure break, there is certain closure in the crack, can not make the crack keep maximum rating;
5. the crack is shorter;
6. explosive payload is little
Obviously, adopt the pressure medicine charge constitution of same kind, same specification, P when the pressure break medicine burns---the pulse phenomenon of t curve is not obvious, the number of times of pulse seldom, crest and trough difference are minimum, make that post-fracturing crack is little, fracture length is short, and units increased in production is little, and period of validity is short.
Technology contents
The purpose of this utility model overcomes above weak point exactly, for volume increase significantly, improves fracturing effect, prolongs a kind of flash gas energy pressure cracking device that increases production period of validity and design.
The utility model be achieved in that by tubing string 1, pressure break medicine 2, contract advance grain 3, proppant 4, slow burning powder 5, pallet 6 are formed, and tubing string 1 is arranged on the pallet 6, have contract to advance grain 3, proppant 4 in the pressure break medicine 2, placement slow burning powder 5 in the middle of the pressure break medicine 2.
The utility model also adopts following technical scheme:
Small size pressure break medicine 7 can also be placed in the centre of pressure break medicine 2.
Pressure break medicine 2 can also be a gunpowder.
Pressure break medicine 7 can be a gunpowder.
Tubing string 1 can be a cable.
Advantage of the present utility model is: adopt the pressure break medicine of different performance, different size, different burning velocities when the design charge constitution, charge constitution can be realized poor, the flash fracturing effect repeatedly of bigger Wave crest and wave trough.
Description of drawings
Fig. 1 is P---the t curve map that in the past installs;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the another kind of structural representation of the utility model;
The P of Fig. 4 text utility model---t curve map.
Concrete enforcement
1. with slow burning powder 5 (or minor diameter fast burn medicine), as Fig. 2, shown in Figure 3, be placed on than in the middle of the major diameter fast burn medicine, when the fast burn medicine was burned to slow burning powder, burning velocity reduced, and pressure is also along with reduction.In like manner, P descends when major diameter fast burn medicine is burned to minor diameter fast burn medicine, and P descends, and combustion speed is also along with decline, so can realize stronger, flash fracturing effect repeatedly repeatedly.
Proppant 4 is placed between the pressure break medicine 2, or proppant 4 is sneaked in the pressure break medicine 2, when the gas of pressure break medicine 2 burning generations entered the stratum, proppant 4 was also brought in the crack that has pressed off by gas simultaneously, becomes permanent supporter.
The utility model effectively avoids pressure to disappear, and the crack, back diminishes, closure, prolongs volume increase (augmented injection) phase and place proppants 4 in the middle of pressure break medicine 2, or just proppant 4 is sneaked into wherein when making pressure break medicine 2 and get final product.
Claims (5)
