原先使用的虹吸测斜仪,测斜深度是靠不同直径的咀子来调节的。井越深,咀子内径越小,成功率就越低,而且钻具在井底静止的时间长,所以很不安全。一般到两千米以后就不再使用。江汉油田油层埋藏较深,一般都在三千米左右,地层倾角大,井眼易斜,在钻井过程中测斜次数比较频繁,原用的虹吸测斜仪已不能满足需要。为此,我们在原有基础上作了 Originally used siphon inclinometer, measured oblique depth by different diameter Tsui to adjust. The deeper the well, the smaller the Tsui inner diameter, the lower the success rate, and the drill in the bottom of the well for a long time, it is not safe. Generally no longer used after two thousand meters. Jianghan Oilfield deeper buried reservoir, are generally about three kilometers, stratum dip angle, borehole easy to ramp, in the drilling process more frequent inclinations, the original siphon inclinometer has been unable to meet the needs. To this end, we made on the basis of the original
