经过多年的发展,虽然我国常规水平井技术比较成熟,但就水平井技术整体而言,仍处于初级阶段,与国际先进的钻井技术还有一定差距。水平井技术发轫于美国。20世纪80年代,水平井已经在美国、加拿大、法国等国家得到广泛工业化应用,并由此形成一股研究水平井技术、应用水平井技术的高潮。近年来,发达国家水平井技术持续进步,应用规模越来越大。国外油田服务公司把水平井作为满足油公司的需要、抢占技术制高点和市场、保持领先地位和扩大市场份额的主要手段之一。
After years of development, although horizontal well technology in our country is relatively mature, horizontal well technology as a whole is still in the initial stage and there is still a certain gap with the international advanced drilling technology. Horizontal well developed in the United States. In the 1980s, horizontal wells have been widely industrialized in the United States, Canada, France and other countries. As a result, a horizontal well technology and horizontal well technology have been formed. In recent years, horizontal well technology in developed countries has been making continuous progress and the scale of application has been growing. Foreign oilfield service companies regard horizontal wells as one of the main means to meet the needs of oil companies, seize the technological commanding heights and markets, maintain their leading position and expand market share.
