火山岩储层综合评价方法与应用——以松南气田营城组旋回三为例
|
摘要
综合利用钻井、测井、地震和产能等资料,通过对松南气田营城组火山岩的岩性、岩相、储层物性和火山机构相带分布等特征的深入分析,建立了研究区营城组火山岩储层综合评价方法。依据影响火山岩储层质量的因素,首先选取了储层评价的7个关键参数,然后根据专家经验对参数赋值计算,最后进行了单井储层定量评价,结果表明,研究区营城组旋回三火山岩主要发育Ⅰ类和Ⅱ类储层。结合松南气田营城组旋回三火山岩相和火山机构平面分布特征,对研究区不同类型火山岩储层的分布进行了预测,明确了研究区下一步勘探与开发的重点区块。
According to the volcanic oil and gas reservoirs in Yingcheng formation,Songnan gas field,a comprehensive evaluation method for volcanic reservoirs was established by drilling,logging,seismic and production capacity,etc.,and through the deep analysis of volcanic lithology,lithofacies,physical properties of reservoirs and distribution of facies zones of volcanic edifice in Songnan gas field.According to the influeuce factors on the quality of the volcanic rock reservoirs,the seven key parameters for evaluation of reservoirs were selected.Then,the parameters were assigned according to export experiences.Last,the quantitative evaluation of single well reservoir was made.The results suggested that the typeⅠ and type Ⅱ reservoirs were mainly developed in volcanic rocks of the third cycle of Yingcheng formation of study area.Combined with the plane distributions of volcanic facies and volcanic edifice,different kinds of reservoir distributions were predicted,and the focus blocks of further exploration and development were defined.
