玛北油田MA131井区xia72井断块下三叠统百口泉组油层段多井钻遇钙质砂砾岩,气测全烃含量低,储集层物性和含油性差,影响了水平井油层钻遇率和后期水平井部署。根据岩心、测井、地震等资料,对xia72井断块百口泉组钙质砂砾岩的成因、识别方法及分布规律进行了研究。结果表明,研究区钙质砂砾岩的钙质胶结物形成于成岩晚期,钙质胶结物对储集层具有破坏作用,钙质砂砾岩的分布主要受沉积相和早期断层控制,具有高电阻率、高密度和低声波时差的测井响应特征,地震剖面上表现为“亮点”反射特征。采用最大似然体、均方根振幅及最大振幅,对研究区钙质砂砾岩分布进行了预测,其中,最大振幅能够精确反映其展布特征。研究区钙质砂砾岩表现为受沉积微相控制的团块状和断层控制的南北向条带状分布特征,根据此预测结果,对27口水平井的部署进行优化。

In this paper, we present a metamaterial structure of Dirac and vanadium dioxide（VO2） and investigate its optical properties using the finite-difference time-domain（FDTD） technique. Using the phase transition feature of VO2, the design can realize active tuning of the plasmon induced transparency（PIT） effect at terahertz frequency, thereby converting from a single PIT to a double-PIT. When VO2is in the insulating state, the structure is symmetric to obtain a single-band PIT effect. When VO2is in the metallic state, the structure turns asymmetric to realize a dual-band PIT effect. This design provides a reference direction for the design of actively tunable metamaterials. Additionally, it is discovered that the transparent window's resonant frequency and the Fermi level in this structure have a somewhat linear relationship. In addition, the structure achieves superior refractive index sensitivity in the terahertz band, surpassing 1 THz/RIU. Consequently, the design exhibits encouraging potential for application in refractive index sensors and optical switches.
