- Water isotope technology for tracing groundwater movement
水同位素技术示踪地下水活动 - 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。 - This article introduced the method of geological investigation of nanling tunnel karst disease , elaborated the tunnel engineering geology conditions , especially the karst water , the karst water power channel and the harm of karst water , and analyzed the cause that produced the karst disease
摘要南岭隧道岩溶地下水活动造成地表坍陷、洞内泥砂淤塞等病害，其原因在于隧道施工遗留的导洞长期疏排岩溶水，采用地质测绘、物探、钻探、水文地质试验等综合勘察方法，查明地下水通道位置、地下水流速、流向，针对病害原因，提出拦截、封团、疏排、填充等综合整治方案。
