欠压实带与超压带的测井识别 - A simple pore pressure estimation method for a disequilibrium compaction shale using sonic velocity
利用声速检测欠压实泥岩异常高压的简易方法与应用 - It was primarily formed by undercompaction , hydrocarbon generation and tectonic compression
柴北缘异常高压主要由欠压实作用、生烃作用及构造挤压作用形成。 - Abnormal high pressure is found from neogene to jurassic in leughu - nanbaxian strnctural belt in the northern margin of qaidam basin , and mostly occurs in undercompaction shale
摘要柴北缘冷湖南八仙构造带从新近系到侏罗系普遍存在异常高压，且通常发育在欠压实泥岩中。 - 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。
