geothermal gradient meaning in Chinese
【地质学；地理学】地温梯度〔每趋向地心60英尺，温度升高华氏一度〕。
Examples

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。 - Based on analysis of geologic foundation record about pingzhuang basin , a lot of sino - foreign geothermal geology record and investigation of field geology , measuring of ground temperature in person and geo - chemical analysis of ascension spring , gushing water of fault , the fact that the anomaly of geothermal gradient of pingzhuang basin , which is in region of low geothermal gradient , is caused by redistribution of conduction - oriented geothermal heat flow which is result from upheaval and depression of basin foundation bed is pointed out . after the field of ground temperature is simulated under the background of conduction - oriented geothermal heat flow by means of ansys , the characteristic of ground temperature distribution of top surface of basin foundation bed ( yixian team ) is revealed . the sound condition of transmissibility fault and feeding water source , which are imperative in formation of the low - medium temperature geothermal system of convective type , is possessed in pingzhuang basin
通过对平庄盆地基础地质资料、国内外大量地热地质资料的分析和野外地质调查、矿井实测地温以及上升泉、断层涌水的地球化学分析等工作基础上，指出地处低地温梯度背景区的平庄盆地地温梯度异常是由于盆地基底隆起和坳陷引起传导型大地热流再分配所致；运用州sys数值模拟了大地热流向地表传导背景下的盆地地温场，从而揭示了盆地基底(义县组)顶界面地温分布特征；阐明了盆地具有形成中低温对流型地热系统所必需的导水断裂、补给水源等的良好条件，中低温对流型地热系统是地热勘查的主要对象；圈定了平庄盆地北部朝阳沟?骆驼营子地热勘查远景区。 - Through studying it is shown that in chagan sag , the geothermal gradients in the center are higher than those around the sag margin and major factors influencing the characteristics of temperature field distribution are the property of geotectogenesis and the differences in tectonic portion , lithology and underground water behaviour ; there are three types of mudstone compaction , i . e . normal compaction , undercompacition and overcomepaction ; there are two pressure systems in sandstone reservoirs , i . e . normal pressure and negative pressure systems and the strata ' s being uplifted and denuded is the key factor leading to the formation of the negative pressure system in reservoir ; and the distinctive temperature - pressure field characteristics in the sag are possessed of important petroleum geological significance in hydrocarbon source maturity , hydrocarbon generation , widening on oil and gas exploration domain and selecting exploration targets , etc
研究表明，查干凹陷中心的地温梯度高于凹陷边缘，大地构造性质及所处构造部位、岩性与地下水活动的差异是影响凹陷地温场分布特徵的主要因素；泥岩压实存在正常压实、欠压实和过压实三种类型，砂岩储层段压力类型可分为正常和负压两个系统，地层抬升剥蚀是导致储层负压系统形成的主导因素；凹陷独特的温压场特徵对烃源岩成熟、油气生成、油气勘探领域的扩大及勘探方向的选择等具有重要的油气地质意义。
