井壁稳定剂
一、产品描述: 钻井液用井壁稳定剂是石油钻井过程中性能优异的井壁稳定助剂。其基本原料是石油沥青。外观为棕褐色易碎薄片或流动性粉末。密度0.98g/cm3,产品含有很高的水溶性成分和一定的油溶成分,具有优良的乳化性能,适用于各种钻井液体系。二、质量指标: 三、用途: 可使淡水或盐水与石油乳化;抑制钻屑的分散,稳定泥浆切力;控制高温高压滤失量,产生薄而坚韧的泥饼;降低钻杆扭矩;封堵井筒微裂缝,保持井眼稳定。 ● 稳定页岩地层 ● 减少转动扭矩和防止遇卡 ● 石油包括原油、废机油、柴油的代用品 ● 抑制钻屑的固体分散 ● 控制高温高压滤失量 ● 产生薄而坚韧的泥饼 ● 对产油气层无损害四、推荐加量 1~4% 五、贮存与包装: 内衬塑料袋,外用三合一纸袋密封包装,每袋净重25㎏,在贮运中,因其水溶性、忌散包。受潮不影响使用。
One, product deSCRJPTion: drilling borehole stabilizer in the process of drilling the wellbore stability excellent performance additives. Its basic materials are petroleum asphalt. The appearance of Tan frangible tabs or flowing powder. Density 0.98g / cm3, products containing highly soluble constituents and certain oil soluble ingredient, has excellent emulsifying properties, applicable to all kinds of drilling fluid system. Two: three, quality index, use: can be made of fresh water or brine and emulsified oil; inhibition of drilling cuttings dispersion, stable mud shear; control of high temperature and high pressure filtration, to produce thin and tough mud cake; reducing the torque of the drill rod; plugging wellbore cracks, maintain wellbore stability. The stability of shale formation decrease rotational torque and preventing encounter card oil include crude oil, waste oil, diesel substitute. Inhibition of drilling cuttings solid dispersion control high temperature and high pressure filtration, to produce thin and tough mud cake on the oil reservoir damage. Four, recommended dosage 1 ~ 4% five, storage and packaging: lined with plastic bag, topical application of three in one paper bag sealed packaging, net weight of 25 kg per bag, during storage, due to its water solubility, avoid bulk pack. Damp does not affect the use.
