应用经典层序地层学的理论和方法,综合分析了钻测井以及三维地震等资料,将阿姆河右岸中下侏罗统划分为两套三级层序,自下而上命名为SQ1和SQ2。通过分析岩石类型、沉积构造、测井相特征、地震相特征等相标志,主要发育沉积相类型为湖泊相和三角洲相。提取两套层序均方根振幅属性,结合钻井相及地震相研究,确定研究区沉积相平面展布模式。
Based on the theory and method of classic sequence stratigraphy, this paper synthetically analyzes drilling and logging data and 3D seismic data, and divides the middle and lower Jurassic of the Amu Darya into two sets of third-order sequences, named SQ1 and SQ2. By analyzing the phase sign of rock type, sedimentary structure, well log facies and seismic facies, the main types of sedimentary facies are lacustrine facies and delta facies. The root mean square amplitude properties of two sequences were extracted. Based on the study of drilling facies and seismic facies, the sedimentary facies plane distribution pattern in the study area was determined.
