摘要
In order to improve the identification of thin sand body according to the seismic data of Carboniferous Kalashayi Formation in Block 3 of Tahe Oilfield,the reservoir forecasting results by the means of seismic data frequency extraction,frequency separation and high resolution sensitive parameter inversion were compared,and then high resolution sensitive parameter inversion was considered as the main forecasting method for sand body reservoir of Kalashayi Formation.The response of sandstone and mudstone to acoustic travel time was discussed,and the relationships of spontaneous potential,natural gamma and porosity compensated neutron log to acoustic travel time were studied;the results showed that the relativity between spontaneous potential and acoustic travel time was best,so spontaneous potential was selected as the optimal electrical sensitive parameter of high resolution sensitive parameter inversion.The results showed that the inversion results were good according to the evaluation on well point inversion,profile inversion and plane inversion,and could be used to forecast reservoir of Kalashayi Formation in Block 3 of Tahe Oilfield;the explanation and description of space distribution of Carboniferous sand body could be explained and described easier;the reservoir model of Carboniferous Kalashayi Formation in Block 3 of Tahe Oilfield was built.
