锦136井区储层预测及评价
|
摘要
随着勘探程度的不断提高和勘探领域的不断延伸,我国陆上油气勘探已经进入到了一个岩性油气藏勘探和构造油气藏勘探并重的新阶段,寻找小幅度构造油气藏、老区滚动扩边以及岩性地层油气藏成为为主要对象勘探。
本文主要应用测井、钻井、垂直地震剖面、地面地震资料,综合运用物探处理方法和地质工作方法,通过构造、沉积、储层分析,完成了锦136井区储层预测及评价工作。发挥VSP方法的优势,充分利用零偏和非零偏处理成果,准确标定兴隆台油层和于楼油层顶底界的地震反射层位,建立可靠的时深转换模型,精细解释井旁构造,提高了三维地震构造解释的精度。在钻井资料约束下,参考生产动态信息,实现精细构造解释,并进一步进行波阻抗反演,反演成果对砂体对比和有利储层预测有很好的指导作用。
经本文研究表明锦136井区的于楼和兴隆台油层,断层比较发育,为小断块油田。经地震和钻井落实,本区在于楼和兴隆台油层,共发育大小断层10余条,通过沉积相分析,详细研究了锦136井区各主要目的层段沉积相空间展布特征,发现S1下兴隆台油层Ⅰ油层组、S1中于楼油层Ⅱ油层组和S1中于楼油层I油层组都是浅—半深水环境的扇三角洲前缘亚相沉积。最后采用波阻抗反演技术对该区砂体分布进行了预测,为圈闭评价及井位部署提供了可靠依据。
With the increasing of exploration degree and the continuous extension of the exploration area, continental hydrocarbon exploration has entered a new stage both on the exploration of lithologic reservoirs and the exploration of the structural reservoir of China. Finding low abundance of the structural reservoir, expanding the reserves exploitation of maturing field and lithologic reservoirs is the main target to explore.
This paper mainly applied the methods of logging, drilling, VSP(vertical seismic profile), seismic data, multipurpose utilizing geophysical prospecting and mine geology, through construction, sedimentation and reservoir analysis, which completed the reservoir prediction and evaluation of Jin 136 well area. Making full use of zero partial and nonzero partial treatment results of the advantage of VSP method, and also calibrating seismic reflection horizons Xinglongtai reservoir and the oil floor of Yulou reservoir to making a time depth conversion model reliable, to explain the borehole-side structure meticulously, which improve the accuracy of 3D seismic precision description. In drilling material constraints, referencing production dynamic information to bring about fine structure interpreting, and more processing wave impedance inversion, and the achievement of inversion have a good directive function for correlation of sand body and advantageous of reservoir prediction.
This paper shows that Yulou reservoir and Xinglongtai reservoir are craven faulted oilfields in Jin 136 well area, as faults are well developed. With the seismic and drilling putting into practice, this area developed every size faults more than 10 totally in Yulou reservoir and Xinglongtai reservoir. Researching on distribution character of sedimentary facies on main objective interval in Jin 136 well area through the analysis of sedimentary facies, which finding S1下of XingⅠoil reservoir group, S1中of YuⅡoil reservoir group and S1中of YuⅠoil reservoir group all are fan-delta front intrafacied in shallow-half profundal zone. Finally using wave impedance inversion technology to forecast sand bodies distribution, which provide reliable basis for evaluationoftrap and well placement.
