Kinetic Model of Clay Mineral Transformation and is Applications
-
摘要: 本文讨论了粘土矿物转化的化学动力学模型及其应用。对于某一地区，粘土矿物蒙皂石向伊利石的转化主要受温度和时间的影响，可以用化学动力学一级反应的模型描述，这一模型可用于：（１）反演古大地热流；（２）模拟成岩史；（３）在盆地内没有钻井的区域预测地层的成岩阶段。Abstract: The kinetic model of clay mineral transformation and is uses are studied in this paper. The model can be applied to:(1)Determination of paleoheat flux;(2) Modeing of diagenetic his-tory;(3) Predictation of the diagenetic stages of the formation in the region without drilling wells.With the increase of burial depth and temperature, clay mineral smectite in the formations transform into illite,which leads the smectite layers (5%)in the smectite/ illite mixed layers (I/S) become fewer and fewer. The transformation of smectite to illite obeys first一order ki-netics. 5% in I/S is a function of temperature and time,and the measured 5% in I/S is a comprehensive effect of temperacare and time during geological history, So the paleoheac fluX can be determined using mcasured S% in I/S, We derermined the palnoheat flux of Well Changcan一1 in geological history using this modelra. So the diagenetic history of scraca can be modals by computing S% in IIS dung geologi-cal history. We modeled diegcnelic history of Well Tangcan一1 in Yi一Shu Graben using mea-surcd S%in I/S as well as paleocemperacure and vitrinire refleccancc R%.The isogram of S% in I/S can be made on the base of modeing the burial history and thcrmal history of all the drieng wells and ficticious weds,then the diagenctic stage of the for-mation can be predicted, We diuided the diageaecic stage of Eb2 formarion in Tegyuan Fault-ed Basin,Yi一Shu Grabea using S% in I/S contour map and R%contour map.
