在螺杆泵采油技术现场应用过程中,螺杆泵专用驱动杆的研制开发,起着至关重要的作用.由于杆柱做旋转运动,要求杆柱必须具有较高的抗扭强度和抗拉强度,不能用常规抽油杆来代替,需研发出适合螺杆泵工作特性的专用驱动杆.实心锥螺纹SHY级工艺驱动杆经过多次改进后,各项技术指标都有了较大的提高,能够充分满足目前在用的各种型号螺杆泵生产实践的需要,收到了较好的应用效果. 相似文献

螺杆泵是目前油田生产中广泛应用的一种采油设备,其泵效的高低关系到系统效率、节能降耗、工作寿命等.针对提高井下螺杆泵泵效,分析了螺杆泵转速对油井的泵效影响,通过公式及曲线的分析和现场实验发现,适当降低转速,合理增大螺杆泵排量,可以提高螺杆泵的泵效,在一定程度上还可减少螺杆泵的磨损,延长使用寿命. 相似文献

鉴于螺杆泵适用于泵送高黏、磨蚀性流体的特性,使得该种机采方式在重油冷采的生产井中得到广泛应用.然而,对于热力采油措施井来说,常规螺杆泵因定子使用的是橡胶制品,故显现出其对160℃以上高温的不适应性.一种可避免橡胶老化的全金属螺杆泵得以研发.2005年初,对全金属泵在温度大于200℃的超重原油介质中进行了有效性测试.当泵速350r/min时,压力升至75bar,排量达到260m3/d.这种金属螺杆泵的排量范围高达1000m3/d. 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
