机械比能在曹妃甸A油田储层有效性定量评价中的应用

Application of Mechanical Specif ic Energy in Quantitative Evaluation of Reservoir Effectiveness in Caofeidian A Oilf ield

孔隙度、渗透率参数是评价储层中的油气储存和流动能力是否良好的关键指标。在油气开发阶段,为节约开发成本,如何在井场实现储层的快速定量评价,保证开发储层的定量评价的及时性成为油田开发的重要考验。文章通过挖掘井史数据,利用机械比能建立曹妃甸A油田东三段中、低孔渗砂砾岩储层孔隙度、渗透率模型,对砂砾岩储层的井场钻后快速定量评价进行了分析验证,为油田开发提供了合理的射孔井段及开采措施。

The porosity and permeability parameters are the key indexes to evaluate the good storage and flow ability of oil and gas in the reservoir.In the oil and gas development stage,in order to save the development cost,how to realize the rapid quantitative evaluation of the reservoir in the well site and ensure the timeliness of the quantitative evaluation of the development of the reservoir has become an important test of the oil f ield development.Based on the mining history data,this paper establishes the porosity and permeability model of medium and low porosity permeable conglomerate reservoir in the East third member of Caofeidian A oilf ield by using the mechanical specif ic energy,and analyzes and validates the rapid quantitative evaluation of the drilling site of the conglomerate reservoir,which provides a reasonable perforating well segment and mining measures for oilf ield development.
