Description
Technical Field
The invention belongs to the technical field of oil and gas exploitation perforation fracturing, and particularly relates to a super-energy charge for perforation fracturing of an oil and gas well and a preparation method thereof.
Background
The perforation well completion is the most common well completion mode for oil and gas exploitation and is also an important link of well completion, and the quality of perforation fracturing has important influence on the oil and gas recovery efficiency. In order to obtain better perforation fracturing effect, people continuously explore new perforation technology on the basis of conventional shaped jet perforation. In the seventies of the last century, the composite perforation fracturing technology is popularized in the American oil and gas exploitation process, and a good yield and injection increasing effect is achieved. The composite perforation fracturing is characterized in that solid propellant powder charge is introduced into a perforating device, and when the metal jet of the shaped charge perforates a hole, the solid propellant powder is ignited to generate high-temperature and high-pressure gas to fracture and crack a stratum along a perforation pore channel, so that a plurality of micro cracks are generated, the flow conductivity of a near well zone is improved, and the purpose of increasing the yield is achieved. Through the development of the last fifty years, composite perforation fracturing devices with different powder charging structures such as 'built-in', 'split' and 'external' are formed and widely applied to various oil fields at home and abroad.
Although the charge structure of the composite perforation fracturing is various, the used gunpowder is essentially solid propellant. The solid propellant is combusted in the perforating gun and the shaft to generate gas, local high pressure is formed in the shaft, and then a part of gas enters a perforating pore canal in the stratum through perforations on the perforating gun and the casing to fracture the stratum; at the same time, another portion of the gas that cannot enter the bore interacts with the well fluid and the tubular string in the wellbore. The volumes of the perforation gun, the perforations on the casing and the perforation pore canal determine the quantity of the fuel gas entering the pore canal and directly acting on the stratum, and the effect of the composite perforation fracturing action is directly influenced. The shaped charge is perforated by utilizing metal jet flow, the perforation aperture and the perforation depth cannot be considered, the traditional solid propellant can only generate gas after combustion, the sizes of holes on a perforating gun and a sleeve and the volume of a stratum perforation pore passage cannot be improved, and therefore when the conventional composite perforation fracturing construction is carried out, the quantity of the gas entering the pore passage through the holes is limited, most of the gas cannot enter the pore passage, and the energy is consumed through the interaction between the gas and a pressing and blocking liquid and a tubular column. The perforation holes and the pore canal volume limit the amount of gas entering the stratum to generate effective action, which is the main reason for limiting the construction effect of the composite perforation fracturing technology. Meanwhile, the gas which cannot enter the pore channel interacts with the pressure retaining liquid and the tubular column, so that energy is consumed, the construction efficiency of composite perforation fracturing is reduced, and the risks of accidents such as gun expansion, gun clamping, casing damage and the like are greatly improved.

TABLE 1 chargeability test chart
As can be seen from Table 1:
the comparison of examples 1 to 6 shows that: after the conventional 102 perforating bullet is assembled with the super-energy charging of the embodiments 1-6, indexes of the hole diameter, the hole depth, the peak pressure and the effective acting time of the ground steel target test are far higher than standard requirements, which shows that the super-energy charging of the embodiments 1-6 has a good perforating and fracturing effect, wherein the comprehensive performance of the embodiment 1 is the best.
Comparing example 1 with comparative example 1, it can be seen that: under otherwise identical conditions, the conventional 102 charge assembly incorporates charges charged with only copper oxide, one oxide, with a significant reduction in both peak pressure and active time. Indicating that the charge obtained by adding only copper oxide can not improve the perforation fracturing performance.
Comparing example 1 with comparative example 2, it can be seen that: under otherwise identical conditions, the conventional 102 charge assembly incorporates charges containing only ammonium nitrate as an oxide, with a significant reduction in perforation pore size, peak pressure and effective duration. Indicating that the charge obtained by only adding ammonium nitrate can not improve the perforation fracturing performance.
Comparing example 1 with comparative example 3, it can be seen that: under the same other conditions, the peak pressure and effective action time of the conventional 102 perforating charge assembly are obviously improved compared with the charge adopting epoxy resin as the binder and adopting polybutylidene as the binder. The epoxy resin contains oxygen element, and can generate gas by burning under the condition of no oxygen in the perforating gun, so that the epoxy resin has gas production capability. The result shows that the adhesive with gas production capability can improve the perforation fracturing performance of the charge.
