井壁穩(wěn)定劑
一、產(chǎn)品描述: 鉆井液用井壁穩(wěn)定劑是石油鉆井過程中性能優(yōu)異的井壁穩(wěn)定助劑。其基本原料是石油瀝青。外觀為棕褐色易碎薄片或流動性粉末。密度0.98g/cm3,產(chǎn)品含有很高的水溶性成分和一定的油溶成分,具有優(yōu)良的乳化性能,適用于各種鉆井液體系。二、質(zhì)量指標(biāo): 三、用途: 可使淡水或鹽水與石油乳化;抑制鉆屑的分散,穩(wěn)定泥漿切力;控制高溫高壓濾失量,產(chǎn)生薄而堅(jiān)韌的泥餅;降低鉆桿扭矩;封堵井筒微裂縫,保持井眼穩(wěn)定。 ● 穩(wěn)定頁巖地層 ● 減少轉(zhuǎn)動扭矩和防止遇卡 ● 石油包括原油、廢機(jī)油、柴油的代用品 ● 抑制鉆屑的固體分散 ● 控制高溫高壓濾失量 ● 產(chǎn)生薄而堅(jiān)韌的泥餅 ● 對產(chǎn)油氣層無損害四、推薦加量 1~4% 五、貯存與包裝: 內(nèi)襯塑料袋,外用三合一紙袋密封包裝,每袋凈重25㎏,在貯運(yùn)中,因其水溶性、忌散包。受潮不影響使用。
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.
