潜北地区位于潜江凹陷北部,是江汉油区储量及产量的主要贡献者,勘探开发潜大,是当前乃至今后滚动勘探主力战场之一。针对潜江凹陷潜北地区构造复杂、储层变化快、油藏类型多、成藏控制要素复杂的特点,近两年来针对不同地区地质特点开展了多领域、多类型油藏滚动评价研究,取得了较好的效果,并形成了针对复杂断裂带的滚动评价方法与技术,为江汉油田增储稳产提供了有力支撑。下步将以复杂断裂带滚动勘探技术为依托,按照常规与非常规结合的思路,开展多领域油藏滚动评价,以隐蔽性油藏及致密砂岩油藏滚动评价为重点,寻找和落实可动用地质储量,实现资源接替。 相似文献

乙烯裂解装置结焦抑制技术新进展 总被引:8,自引:1,他引:7
乙烯装置裂解炉炉管结焦是影响乙烯产量的重要因素之一 ,它会使炉管管壁热阻增大 ,热传导率降低 ,使裂解过程能耗增大 ,壁温升高 ,炉管寿命缩短。同时 ,焦垢会使炉管内径变小 ,物料流动过程压力降增大 ,甚至堵塞管道 ,使运转周期缩短 ,产量受到限制。目前 ,全球乙烯工业每年因炉管结焦减产造成的损失约为 2 0亿美元[1 ] 。另外 ,结焦和采用过热气流清焦会使炉管寿命缩短 ,所以炉管通常每 2~ 5年需要更换一次。乙烯生产商每年在炉管上耗费约2 5亿美元 ,其中 80 %用于维修和更换炉管。开发结焦抑制技术对延长装置运行周期、提高裂解炉生产效… 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

《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
