摘要
鱼骨井钻井液与油层的接触面积大,气井对钻井液污染敏感,需要一种适合的完井液保护储层,2007年元月至7月西部钻探克拉玛依钻井公司泥浆技术服务公司根据国内其它油田水平井和鱼骨型水平井钻井液的使用情况,结合克拉玛依油田的地层特点,通过大量的室内试验,开发了2种盐水水包油钻井液配方,分别在克拉玛依油田百重7井区、石南4井区进行了4口井的试验,取得了良好的效果,取得了良好效果。
It is essential for us to choose a kind of appropriate completion fluid on oil & gas reservoir as a kind of protection because of large contacting area and sensitivity of contamination between completion fluids used in horizontal branch wells and oil & gas reservoir.The Karamay Drilling Fluids Technology Company,branch of Western Drilling Engineering Corporation of CNPC has developed two kinds of oil in-salt water drilling fluid through researching a lot of data of horizontal and horizontal branch wells and chemical experiments based on characteristics of stratum of Karamay Oil Field.Also,it works very well through using two kinds oil in-salt water drilling fluids respectively in Bai-zhong-7 & Shi-nan-4 block.
