【摘要】 辽河油田经历了40年的油气勘探,目前已经进入勘探中后期,岩性油气藏勘探逐渐取代了整装构造油气藏的勘探。如何准确地刻画沉积砂体空间展布,预测其含油气性是岩性油气藏勘探的关键。以陈家洼陷主要目的层段古近系沙河街组三段下亚段(Es3L)深水浊积砂体的空间展布形态刻画为例,系统阐述了利用Landmark工作站一体化解释软件结合Strata反演软件进行岩性油气藏勘探的技术与方法,利用三维地震资料详细刻画出沉积砂体的立体沉积模式,预测出与油气关系密切的沉积微相。该方法对深化老区勘探及在盆地坡洼过渡带寻找类似的岩性油气藏具有一定指导意义。更多还原

【Abstract】 Liaohe Oilfield has been explored for nearly forty years,it has been at the middle and late stages of exploration,the over structural reservoir exploration has been replaced gradually by searching of lithologic reservoir.The key point of lithologic reservoir exploration was how to outline the depositional sandbodies distribution and predict its hydrocarbon property accurately.The spacial distribution engraving of deepwater turbidite sandbodies(the lower member of Es3) in Chenjia Sub-sag is used as an example to systematically expound the technique and method of lithologic reservoir exploration by the integration of software of Landmark workstation with strata inversion software.The method of 3D seismic data interpretation is used to denote the three dimensional depositional mode and distribution of turbidite sandbodies.The method can provide a guidance for searching the oil and reservoirs in the matured oil oilfield and other similar reservoir exploration.更多还原
