四川省石油管理局矿机研究大队,根据江汉石油管理局钻井处攻关队改革旧式虹吸测斜仪的经验(编者注:详见本刊1975年第2期),试制了三套井底打开式虹吸测斜仪,先后在三口井上进行了多次投测,最大测斜井深达2846米,测斜成功率为78％。 试用情况表明,改革后的虹吸测斜仪,由于改滴管计时为井底打开,大大提高了测斜成功率,缩短了测斜时间,使用安全方便,受到井队欢迎。 According to the experience of reforming the old-style siphon inclinometer at the Drilling Department of Jianghan Petroleum Administration Bureau (editor’s note: see the second issue of 1975), a trial of three sets of bottom hole open type Siphon inclinometer, successively in the three wells for a number of castings, the maximum measured incline depth of 2846 meters, the success rate of 78%. The trial shows that after the reform siphon inclinometer, due to the opening of the dropper opening for the bottom of the well, greatly improving the success rate of the inclinometer, shortening the incline time, the use of safe and convenient, well team welcome.
