更换修复采油采气井口有哪些方法?

  随着工艺技术的不断提高,采油的型号越来越多,由于采油树的结构型号不同,修井方法和步骤也不同,为了提高开发效果实现带压采油的开发政策,经常实施用带顶螺纹法兰的采油树代替不带顶螺纹法兰的采油树。根据现场修复和更换采油树的不同类型和方法,采油采气井口主要有以下两种修理方法:

  1.无顶丝法兰采油树修复方法

  顶丝法兰生产对与无顶丝法兰采油树的主要区别在于,可以与不压井不放喷的井口装置组合成压井设施,可以进行压井作业,而后者没有压井放喷井口装置不能进行压井作业,无顶丝法兰采油树的修复和更换方法根据井的具体情况和现场设备的材料条件确定,通常采用以下两种方法。

  (1)压井防喷置换法。

  这种方法是利用压井的功能来获得顺利的施工条件,其具体采油采气井口步骤是在处压井拆除更换井口-采油树更换井喷洗井合格后重新投产,这种特点是井内高压液体稳定、可靠,使用压井液压井不易发生井喷事故但其缺点是压井使用压井液尤其是高密度压井液,不仅造成大量的物耗而且容易将污染物注入油层,堵塞油流通道修油井或水井后降低产油量注水量。

  (2)封隔器密封的更换方法。

  用这种方法代替采油树的原理是利用封隔器的封隔功能,采油采气井口配合内部以及井口使井身剖面内的油气暂时无法喷出,从而取代压作业更换井口采油树。

  2.顶部带螺纹法兰的采油树修复方法

  (1)进行采油采气井口施工设计。根据施工井的具体情况和需要修复的内容,根据施工的目的和要求编制具体的施工内容、方法和步骤同时制定防护措施。

  (2)运行油管塞。先关闭采油树的主闸门在排污管的配合下将塞子放入井内,用高压清洗车压制压力只有确认油管通被堵塞后才能进行下道工序。

  (3)提起井口。确认堵头密封后试着释放溢流观察,井口无喷淋时抓紧时间拆下采油树井口螺丝拆下采油树。

  (4)修理或焊接。根据工程建设要求进行修复工作。

  (5)安装采油树。井口部件和设备修复后应及时安装采油树注意拧紧螺旋千斤顶法兰上的螺旋千斤顶,防止井内高压造成油管堵塞。

  (6)打捞堵头。井口故障修复后用动力设备打捞井内的塞子重新投入生产。

Reporters Muzi reports: Mainland Construction Machinery Industry stride towards international

Reporters Muzi reports: Mainland Construction Machinery Industry stride towards international, mainland officials estimate that by 2015, China will become a major exporter of machinery industry, accounting for one-tenth of global demand. Many companies are interested in using Hong Kong's capital market, to expand overseas. However, concerns China's core components of the industry is still dependent on imports, called on the government in the "five" plan to encourage innovation to enhance the content. 5 years up to $ 20 billion exports   Although the global manufacturing industry to enter the adjustment period, but the Chinese industry is still the situation is excellent, the China Construction Machinery Association, Jun Qi in an interview means that next year's construction machinery industry growth may slow, but still maintained double-digit growth . By 2015, industry sales will reach 900 billion yuan, expect profit margins to 7%, of which 30% is exported. He pointed out that estimated that by 2015. the international market demand for construction machinery products will reach $ 200 billion, of which China's exports accounted for $ 20 billion may be about to become a major exporter.   Widely believed that the government's "five-second" planning a little conservative, in which large-scale engineering machinery enterprises as the Mainland, Guangxi Liugong has been set for the next five years, sales of 50 billion plan. Guangxi Liu Gong newspaper that President Yang Yichuan, which accounts for one third of the international export hopes, more than 100 million. He pointed out that China after several years of construction period, the demand for heavy machinery into the saturation plateau, the preparations should be early to go to other developing countries, India, South Asia, South America is a very promising market.   Speed ​​up overseas acquisitions to be listed in Hong Kong   To improve market share overseas, Liugong was first taken abroad in the middle, planned acquisition of Polish HUTASTALOWAWOLA (HSW), which is the second two years ago Zoomlion to € 271 million acquisition of CIFA of Italy's top construction machinery enterprises, the Chinese construction machinery company in the overseas market, the second acquisition.   Yang Yichuan said that the future will continue to identify good acquisition, there are plans to set up overseas headquarters in Hong Kong to co-ordinate all international business, and its push to mature companies listed in Hong Kong to expand its international influence. Called on policy support to help industry   China construction machinery to become a big country, one of the core components is constrained to rely on imports. Zhang, chairman of Elcoteq Heavy steel frankly, the import price for the domestic price of 10 times, he hoped that the Government could take the lead, enterprises and universities to support their own research and development, Yang Yichuan also said that the current R & D costs Liugong 5% of total revenue, the future will gradually improve, but he stressed that this is not a company to resolve the matter, need the government to come forward, the list will be national policy, make overall planning, Japan, for example, is from the R & D to sales are more policy support.   China Construction Machinery Association, Working Committee Secretary-General Feng Gui agents infants and pointed out that China is not without ability, the key is related to consciousness is weak, the government needs determination, hope in the "five" components during the development of supporting policies to encourage the introduction, in order to support industry long-term development.   Been hailed as the dean of large-scale construction machinery Professor Sun Zuwang pointed out that China is technically not particularly difficult to overcome, not the key is to manage with, for example in the production of cleanliness, the workers can not be executed.
