摘要： Disintegrative particles are designed to be blended with and pumped with typical proppant materials, e.g. sand, ceramics, bauxite, etc, into the fractures of a subterranean formation. With time and/or change in wellbore or environmental condition, these particles will either disintegrate partially or completely, in non-limiting examples, by contact with downhole fracturing fluid, formation water, or a stimulation fluid such as an acid or brine. Once disintegrated, the proppant pack within the fractures will lead to greater open space enabling higher conductivity and flow rates. The disintegrative particles may be made by compacting and/or sintering metal powder particles, for instance magnesium or other reactive metal or their alloys. Alternatively, particles coated with compacted and/or sintered nanometer-sized or micrometer sized coatings could also be designed where the coatings disintegrate faster or slower than the core in a changed downhole environment.
摘要翻译：崩解颗粒被设计成与典型的支撑剂材料混合并泵送，例如，砂，陶瓷，铝土矿等，进入地层的裂缝。随着井眼或环境条件的时间和/或变化，这些颗粒将在非限制性实例中通过与井下压裂液，地层水或诸如酸或盐水的刺激流体接触而部分或完全崩解。一旦崩解，支撑剂包内的裂缝将导致更大的开放空间，使更高的导电率和流速。崩解颗粒可以通过压实和/或烧结金属粉末颗粒，例如镁或其它反应性金属或其合金来制备。或者，还可以设计涂覆有压实和/或烧结的纳米尺寸或微米尺寸涂层的颗粒，其中涂层在改变的井下环境中比核心分解更快或更慢。
