精细构造解释与储层预测技术在泌阳凹陷中南部地区二次勘探中的应用 总被引:30,自引:17,他引:13
泌阳凹陷属陆相断陷式碎屑沉积盆地,中南部地区储层为扇三角洲和辫状河二三角洲前缘沉积,相变快,成岩不均一,地震速度变化快,储层呈砂泥薄互层状,圈闭类型有断鼻、断块和地层加岩性圈闭。针对深层系构造特征、储层特征及速度变化特点,采用层位标定与层位综合解释技术、断层精细解释技术和变速成图技术,有效地进行了构造精细解释;采用测井约束波阻抗反演和地震属性分析技术,进行了砂泥薄互层储层预测。研究成果在泌阳凹陷中南部地区二次勘探中取得明显效果。 相似文献

辽河西部凹陷雷家地区广泛发育湖相碳酸盐岩,与之伴生的有大量的湖相泥页岩与方沸石岩。研究表明,云岩含量高低对致密储层的储集性能有较大影响,而云岩类岩石的地震预测难度较大。针对上述问题,开展了基于岩心分析的精细岩性识别,通过岩石物理分析确定杨氏模量与纵横波速比能够较好区分泥页岩,通过杨氏模量与白云岩含量的统计回归确定白云岩含量与杨氏模量的关系;在叠前弹性参数反演的基础上,通过重构白云岩含量进行白云岩含量反演,确定了白云岩含量高的储层平面及纵向分布特征。预测结论与实钻井数据结果吻合程度较高,可有效指导该区致密(储层)油的勘探。 相似文献

东营凹陷民丰断裂带地区地震反演及储层预测 总被引:2,自引:1,他引:1
储层地震预测技术以油藏描述理论为指导,利用由地震资料反演得到的波阻抗或波速数据体,准确地描述储层分布状态和油藏储量规模。研究中综合应用地震解释软件和反演软件各自的优点,针对东营凹陷民丰断裂带地区沙二、沙三段的具体地质情况,开展了全面而系统的研究。通过精细构造解释,建立精细地质模型,采用多井约束反演,进行砂体储层预测。对地震反演资料补充测井数据的高、低频成分之后,波阻抗数据体的频带显著拓宽,剖面内垂向变化趋势合理,分辨率高,据此预测的两个砂体经钻探均见工业油流。 相似文献

地震反反演技术在桥口-白庙地区储层预测中的应用 总被引:4,自引:1,他引:3
桥口—白庙地区地质条件复杂,受构造位置和物源影响其沉积类型亦不相同,砂体分布和岩性变化大,应用地震反演技术,对储层进行预测,为油气分布和控制因素的研究奠定了基础。地震反演和储层预测采用了约束稀疏脉冲反演方法,把叠后的地震反射振幅数据变换为地层波阻抗数据,然后利用反演的波阻抗数据,估算出砂岩厚度和砂岩储层物性参数。根据该项技术,最终生成了各目的层的5类平面成果图,即地层厚度、平均波阻抗、预测砂岩厚度、预测砂岩百分比、预测砂岩平均孔隙度等值图。地震反演与储层预测结果表明,在井均匀分布的约束下,能较好地预测砂岩储集层的平面分布,圈定面积和砂岩发育区,反映出物源方向及可能的油气分布。 相似文献

《Oil and Energy Trends》2008,33(5):6-7
This section summarizes downstream developments of the previous month. Exploration & Production are covered in 'Upstream Review'.
An upsurge of violence in Iraq threatened a recovery in output that began earlier this year. Production in the northern fields hit a post-invasion high of 620,000 bpd in March, rising by 180,000 bpd in one month. Fighting in the south, however, cut production there by more than 100,000 bpd as government troops tried to subdue Shi'ite militias in and around Basrah. Oil installations damaged in the south included a pipeline and a pumping station. The Iraqi government nevertheless announced that oil production would reach 2.9 mn bpd by the year's end, requiring an increase of nearly 500,000 bpd over April 2008 levels. Foreign help is to be sought via a series of technical service agreements and - later this year - an upstream licensing round. Japan's Ministry of Economy, Trade and Industry says it wants a bigger role for Japanese oil companies in both the upstream and downstream sectors in Iraq. Kurdistan says it is negotiating with Baghdad to export oil produced from new oil fields there. The central government does not recognize production agreements drawn up by the Kurdistan Regional Government. The EU - desperate for gas to fill its Nabucco pipeline - has approached Iraq for up to 1 bn cfd. 相似文献

采油过程中,酸化是油气井增产、注水井增注的主要措施。砂岩基质酸化和碳酸岩基质酸化都是在低于储层破裂压力的条件下向地层中注入酸液,溶解地层中的可溶物质,清除孔隙或裂缝中的堵塞物质,从而使油气井增产或注水井增注的一种工艺措施。本文着重讨论了砂岩酸化的设计计算方法,并由此建立一套基质酸化设计方法。 相似文献
