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。

The inhibitive action of tungstate-based inhibitor for the drill pipe made of G105 steel in saltwater drilling fluid was studied using electrochemical impedance spectroscopy,aiming at increasing the service lifespan of the drill pipe in the saltwater drilling fluid.

为了延长盐水钻井液中G105钢钻杆的使用寿命,通过电化学阻抗谱(EIS)的测量分析,对在盐水钻井液中G105钢钻杆的钨酸盐系复合缓蚀剂进行了研究,并采用失重法通过室内动态模拟试验对所获配方进行了验证。

To solve the corrosion of drill pipe, corrosion mechanism of G-105 drill pipe in saltwater drilling fluid was investigated.

为了解决盐水钻井液对钻具的腐蚀 ,通过对现场钻杆腐蚀产物的EDS分析发现 ,其主要成分为铁的氧化物Fe2 O3 ;盐水钻井液对钻具的腐蚀主要是氧的去极化腐蚀 ,且腐蚀产物疏松 ,对钻杆保护作用较差。

Saltwater drilling fluid used in the exploitation of the brine well located around Hongze and Huaiyin undertaken by Jiangsu Oil Field in recent years contains much more CT and is also abundant in K~+, Ca~(2+), SO_4~(2+) etc, so its conductivity is higher.

近年来，江苏油田承钻了位于洪泽、淮阴一带的盐井，使用盐水钻井液，该钻井液中Cl~-含量高，同时富含K~+、Ca~(2+)、SO_4~(2-)等离子，电导率大，另外其中还含有多种成分复杂的添加剂，又因井内温度较高(超过80℃)，钻井液内含有溶解氧，因而对钻具的腐蚀很严重。

Thin under-saturated silicate brine drilling fluid is one of the well-proven technologies for drilling salts and gypsum rocks.

盐泥是盐化工业生产过程中产生的固体废物,稀硅酸盐欠饱和盐水钻井液是盐膏层钻井的成熟技术之一。

Lately, Jiangsu oil field drills lots of salt wells locating in Hongze and Huaiyin, saturated saltwater drilling fluids is used, the concentration of Cl- is very high; various additives are added into the drilling fluids; the conductance of drilling flu.
