摘要： The present invention relates to an apparatus and method for using that apparatus to orient a perforating gun (41) or system to minimize or eliminate the damage that may be caused to exterior control conduits, conductors, devices or to adjacent interior well control lines. The perforating gun (41) or system is attached to a orienting mandrel (99), which has a resilient cam (120) or guide that engages an orienting channel (15) formed on the interior of a specially fabricated tubular member (10). The tubular member (10) is appropriately spaced and properly oriented in relation to the perforating system (41) blast thereby allowing attachement of lines, conduits or devices (6) in the opposite radial direction from the blast of the perforating system (41).

摘要： The present invention provides methods and apparatuses for the enhanced recovery of hydrocarbon fluids from subterranean reservoirs using cryogenic fluids. Using the Earth's geothermal energy to warm cryogenic flood fluids injected into subterranean reservoirs, the pressure within the subterranean reservoir is increased. Consequently, the reservoir conductivity is enhanced due to thermal cracking, and improved sweep efficiency of the reservoir by the flood fluids is provided. This rise in pressure due to the injection of the cryogenic fluid increases the reservoir conductivity enhancement and improves sweep efficiency of the flood fluids, which leads to the production of more fluids from to the subterranean reservoirs.
摘要翻译：本发明提供了使用低温流体从地下储层增强烃流体回收的方法和装置。使用地球的地热能来加热注入地下水库的低温洪水，地下储层内的压力增加。因此，由于热裂解提高了储层导电性，并且提供了由洪水流体提高储层的扫掠效率。由于注入低温流体而导致的压力上升增加了储层导电率的提高并且提高了洪水流体的扫掠效率，这导致更多的流体从地下储层的产生。
