Geotemperature gradient distribution of kuqa foreland basin north of tarim china 塔里木盆地北缘库车前陆盆地地温梯度分布特征
Influence of earth temperature gradient on ground stress calculation in underground mines 地温梯度对地下矿山地应力计算的影响
The transition zone quite often shows a decrease in temperature gradient due to the ability of water to absorb up to a 1 / 3 more heat than rock 由于水具有比岩石能多吸收三分之一热量的能力,因此,这类有变化的地层通常都显示出地温梯度下降的趋势。
The quaternary system is characterized by high geothermal gradient , with low scope of overpressure in its deep and shale caprock saturated with formation water of high salinity 第四系具有较高的地温梯度,深部发育了低幅超压;甘森泉小柴旦基底断裂影响气藏构造的完整性;第四系饱含高矿化度地层水泥岩构成的盖层可以起到一定的封盖作用。
Downhole temperature profiles have been simulated under different conditions of fluid output , production time , off production time , formation parameters , geothermal gradient , bed thickness , welibore radius and so on , and simulation results are analyzed and discussed 本文模拟了产液量、生产时间、停产时间、地层参数、地温梯度、层厚及井筒半径等不同条件下的井下温度场分布,并对模拟结果进行了分析和讨论。
