江汉油田地层倾角大,夹层多,岩性软硬变化频繁,打井时容易产生井斜。因此,解决井斜问题是本地区实现优质快速打井,保证钻井翻番的一个重要环节。从1976年起,我们与管子站、机修部等单位协作,试制成螺旋扶正器。通过11口井的生产试验(累计进尺1250.78 Jianghan Oilfield strata angle, mezzanine and more frequent changes in lithology, hard and soft, easy to produce wells when drilling wells oblique. Therefore, solving the problem of well deviation is an important step in achieving high-quality quick drilling in the region and doubling of drilling volume. Since 1976, we collaborate with the tube station, mechanic and other units to make a spiral centralizer. Through the 11 wells production test (total footage 1250.78
