Description
Technical Field
The invention relates to a heat-resistant mixed explosive for an oil field, belonging to mixed explosives. The method is mainly used in the field of heat-resistant high-energy explosives for oil exploration and exploitation, such as high-temperature perforating bullet charging and the like.
Background
Oil well perforation is a key technology for oil exploration and production. The perforations allow communication between the wellbore and the predicted total reservoir. Effective perforation is vital to correctly evaluating hydrocarbon reservoirs, increasing the productivity of hydrocarbon wells and the recovery ratio of hydrocarbon reservoirs. Meanwhile, the perfection of the perforation technology directly influences the expected productivity of the oil-gas well and the protection of the oil-gas layer. At present, the development of petroleum is towards deep wells and ultra-deep wells, namely, the target horizon of exploration and exploitation is required to be continuously deepened, and along with the continuous increase of exploitation difficulty, the key point is to improve the exploitation rate and the perforation quality.
The perforating charge can be roughly classified into three types according to the heat resistance of the explosive: common perforating bullets, high-temperature perforating bullets and ultrahigh-temperature perforating bullets. Among these, HMX-based explosive compounds are commonly used as the mixed explosive for high-temperature explosive charges, and the formulations are mainly prepared by granulating the military-grade single-substance explosive HMX and a binder in accordance with U.S. LX-04 (85% HMX), LX-07 (90% HMX), LX-10 (95% HMX), LX-11 (80% HMX), and Chinese H781 (95% HMX), 411 (94% HMX). The patent aims at the application requirement of the high-temperature petroleum perforating bullet, the residual explosive modeling powder tailing in the production process of the weapon equipment is used as the raw material, and the mixed explosive for the high-temperature resistant petroleum perforating bullet is prepared in a roller dry mixing mode, so that the recovery and the reutilization of typical explosive tailing resources are realized.

In order to achieve the purpose, the invention adopts the following technical scheme:
an explosive for a high-temperature perforating bullet uses waste explosive modeling powder tailings as raw materials; wherein the content of HMX is more than or equal to 85 percent.
The embodiment also provides a preparation method of the explosive for the high-temperature perforating charge, which comprises the following steps: the preparation method comprises the following preparation steps:
(1) Ingredients
Sieving the waste explosive molding powder tailings with the HMX content of more than or equal to 85 percent, and weighing undersize products;
(2) Mixing material
Dry-mixing different explosive tails in a roller at a low speed;
(3) Discharging
And stopping rotating the roller, opening the discharge valve, slowly flowing the material into the paper bag, and packaging to obtain a finished product.
In some embodiments, the waste explosive modeling powder tailings are screened through a 6 mesh screen.
In some embodiments, the drum speed (10-30) r/min.
In some embodiments, the mixing time is (20-40) min.
In some embodiments, the 20L drum feed mass range is (10-30) kg.
