completion brine

Solid free composive salt drilling and completion fluids are used increasingly for their good oil layer preservation ability, however, they can cause corrosion of the drilling tool due to large amount of monovalent and bivalent organic or inorganic cations and anions adding to the system for maintaining its density.

无固相复合盐水钻井完井液,因其具有较好的油气层保护作用在现场中得到了越来越多地应用,但加重时需要加入大量的一价、二价有机及无机阴、阳离子,它们对钻具构成一定的腐蚀作用。

In districts Hongze and Huaiyin of Jiangsu oil fields, where the reservoirs are > 5000 m in depth and of temperature ~ 80℃, severe corrosion problems are encountered with G105 steel drilling tools when using salt water drilling fluids (SWDFs).

江苏油田洪泽、淮阴地区井深超过500-米,地温80℃左右,使用盐水钻井液钻井时G105钢钻具腐蚀严重。

In order to safe and fast drilling in creeping salt bed in S84 Well, some technological practices were adopted, such as unsaturated salt water drilling fluid system, measurement technique of formation creeping rate and homoion effect technique, which can solve some problems during drilling operations in creeping salt beds.

S8 4井在钻进过程中遇到塑性蠕动非常严重的盐膏层 ,为安全快速钻进 ,采取了应用欠饱和盐水钻井液体系、地层蠕动速率测定技术、同离子效应技术等工艺措施 ,较好地解决了该井盐膏层钻井存在的一些问题 ,为日后钻穿盐膏层提供了借

Field applications of saturated salt water drilling fluid system show that this system can not only meet the demands for conventional drilling operations but also meet the demands for under balanced drilling.

江汉油田王平 1井在钻进车档断层盐间非砂岩储层时采用了饱和盐水钻井液体系 ,现场施工表明 ,该体系不仅满足了常规钻井施工需要 ,也满足了欠平衡压力钻井的需要。
