摘要
针对准噶尔盆地腹部侏罗系碎屑岩储层流体含量精细化评价难度大的问题,通过试验数据分析,对录井参数进行刻画,利用核磁定量化参数及岩心流动试验精细刻画储层流体含量,显微荧光薄片观察油水在储层渗流通道中的微观分布特征,形成碎屑岩储层流体性质的定量化与可视化评价方法,从而提高碎屑岩储层流体评价准确性。D13井、F003井及M23井的现场应用表明,碎屑岩储层流体性质的定量化与可视化评价方法能够从微观角度直观展示储层流体赋存状态,为试油选层、优选改造工艺提供决策依据。
In allusion to the problem of difficulty for a fine evaluation of clastic rock reservoir fluid of Jurassic System in the hinterland of Junggar Basin,the mud logging parameters were depicted by analyzing the test data,the content of reservoir fluid was described by NMR quantitative parameter and core flow test,the microscopic distributive characteristics of oil and gas in the percolation channel were observed by microscopic fluorescence sections,aquantitative and visualization evaluation method of fluid property in the clastic rock reservoirs was established,therefore the precision of clastic rock reservoir fluid evaluation was improved.Field applications in Wells D13,F003 and M23indicate that the quantitative and visualization evaluation method of fluid property in the clastic rock reservoirs can display the occurrence state of reservoir fluid microscopically and directly,it provides a basis for decision making for stratigraphic selection of oil testing and optimization of reconstruction technology in the oilfields.
