高密度低渗透油田开发过程中,实施分层注水开发的模式,达到分层的开采效率。当油田开发进入到中后期,分层注水的效果不能满足油田产能的要求,因此,有必要研究低渗透油田的分层注水技术措施,解决油田产能下降的问题,不断提高油田开发的经济效益。 相似文献

注水工艺技术是油田开发过程中比较常用的一项开发技术,在该技术应用过程中,为全面提升油田的注水效率,缓解不同层间、层内以及不同平面之间的矛盾,现阶段大部分地区的油田都运用了分层注水技术,并且通过对该技术进行不断优化与完善,得到了比较理想的开采效果. 相似文献

现阶段已有许多全新材料、工艺与方法在油田开发过程中使用,但是最为普遍的依旧是注水开发。从油田注水开发过程进行分析后可以发现,油田注水开发效果会受到多种客观因素的影响,最为直接的就是注水水质。这也是油田注水开发不能实现对预期效果满足的原因之一。本文主要针对水质对油田注水开发效果的影响进行分析,这对油田开发水平的进一步提升有重要作用。 相似文献

注水开发一直是我国大部分油田的主要开发方式,即便是进入高含水或特高含水期,注水开发依然发挥着主力开发作用。但开发后期,注水开发的效果会随着开发的深入而受到影响,合理的评价老油田注水开发效果,提出有效注水的增产措施方案,以保证油田开发的产量和效益。 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

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
