Gunpowder of the present invention in use, after slug fluid column drops to zone of interest, due to action of gravity AUTOMATIC ZONING, the maximum liquid gun propellant of density is positioned at orlop, pressure gear liquid level is above liquid gun propellant, hydrophobic spacer pad keeps off between liquid at liquid gun propellant and pressure, has well intercepted liquid gun propellant and pressure gear liquid.
Solid-liquid pressure break medicine system of the present invention by easily productions, low price, safety performance reliably component form, and mature preparation process, burn controlled, stablize.Be mainly used in the oil-gas field production field of deep-well, ultra-high voltage, low permeability formation.Utilize the difference of energy between solid gunpowder and liquid gun propellant, combustion speed and explosive load, first stratum is pressed off by solid gunpowder, produce many radial major fractures and preliminary extension, reduce terrestrial stress, the useful effect of recycling liquid gun propellant longer time, in stratum, greatly extends and expands fracture length, link up natural fissure, complex fracture network can be formed in the area on a large scale of nearly well, create conditions for later stage waterfrac treatment forms complicated volume seam net, and then improve oil and gas production.
Adopt manometric bomb, pressure calibration machine, CYG401 type flush package high frequency dynamic pressure transducer and the gunpowder of SP1461D type function signal generator to the embodiment of the present invention 1, embodiment 3, embodiment 5 and embodiment 7 carries out the test of pressure versus time.Test result as shown in Figures 1 to 4.Fig. 1, Fig. 2 and Fig. 3 are respectively the pressure versus time test pattern of the gunpowder of the embodiment of the present invention 1, embodiment 3 and embodiment 5, as can be seen from the figure, after solid gunpowder lighted in testing by the gunpowder of embodiment 1, embodiment 3 and embodiment 5,10ms internal pressure raises rapidly, rate of pressure rise is respectively 18.9MPa/ms, 21.3MPa/ms, 17.8MPa/ms, much larger than the 2MPa/s of waterfrac treatment; Then have a little flex point, and have small size decline, this shows that the speed that high energy gas discharges is greater than gas generating rate, and stratum is become many cracks by pressure break open form; Liquid gun propellant is lighted subsequently, and crack release high energy gas speed is less than gas generating rate, and continue in pit shaft to build the pressure, pressure rises gradually and tends to be steady, and extends fracture length and scale to greatest extent; Final liquid combustion rate of powder terminates, and pit shaft internal pressure declines.The gunpowder of embodiment 1, embodiment 3 and embodiment 5 all effectively can be made fast and split reservoir formation multiple cracking, and the maintenance pit shaft high pressure of energy long period, be conducive to extension and the expansion in crack.Fig. 4 is gunpowder, the separately solid gunpowder of the embodiment of the present invention 7 and the pressure versus time test pattern of independent liquid gun propellant, as can be seen from the figure, it is fast that solid gunpowder fires pressure break rate of pressure rise, peak pressure is high, although crack can be formed by fracturing stratum, but it is short effectively to hold the pressure time, and fracture length and the scale of formation are limited; Although and liquid gun propellant fires pressure break effectively to hold the pressure time long, peak pressure, rate of pressure rise are little, so that when running into deep-well, surpressure well, do not turn up the soil layer or enable pressing off of pressure is controlled by the restriction of terrestrial stress difference and is difficult to formation many random orientations cracks; And solid gunpowder and liquid gun propellant compound fire pressure break needs ingenious both utilizations mutual supplement with each other's advantages inferior position according to stratum, taken the lead in firing rapid pressure by solid gunpowder, system is split stratum and is formed many random orientations cracks, then light liquid gun propellant and for longer periods extend fracture length, expand crack scale, link up natural fracture to greatest extent, reduce oil and gas flow resistance, improve per-well production.
The above; it is only preferred embodiment of the present invention; not any restriction is done to the present invention, every above embodiment is done according to invention technical spirit any simple modification, change and equivalent structure change, all still belong in the protection domain of technical solution of the present invention.
