  petroleum quality
     With the degrading of petroleum quality and increasing of sulfur and metals content impurity in the non distillate oil, corrosion problem of the quenching ring in the gasifire has variously threatened the safely and stability of production,as the material of the quenching ring can not resist corrosion and corrosion fatigue when the temperature is over 1 000 ℃ It is possible to solve this problem by means of concealment of the quenching ring
     随着原油品质的恶化 ,渣油中的硫及金属杂质含量增加 ,气化炉中激冷环的腐蚀问题已严重威胁了生产的安稳运行 ,其失效的原因是激冷环材料不能抗 1 0 0 0℃以上介质的腐蚀和腐蚀疲劳 ,用激冷环隐蔽技术解决该问题是可行的。

A unique emulsion type wax crysta1 modifier for low permeability remote wells in Daqing Oilfield, namely DODP-2, was developed recently. The in-lah preparation procedures, as well as the laboratory evaluation results are given in this paper. In field application, DODP-2 can be injected in batch into the annular space between the tube and the casing of the well, diluted with water in advance. Then wax inhibiting effects, as well as .pour point depressing effects will be obtained. The laboratory data showed that with a dosage of 25og DODP - 2 product(active content 20%wt. ) per metric tonne of prod ucd crude oil, the pour point of the produced liquid can he lowered by 15 T, and awax inhibiting rate of 52. 8% can be obtained as well.

大庆外围低渗透油田由于油井产液量低和原油品质差,造成开采成本非常高。如能通过采用投加少量降凝剂的方法来大幅度降低油井采出液的凝点,实现常温集油,则可大大简化现有集油流程,使得这些低渗透油田的开采成本得到显著降低。为此研制了一种适用于大庆外围低渗透油田的乳液型防蜡降凝剂DODP—2,生产中将其稀释后注入到油井油套环形空间,能起到防蜡和降凝作用。室内试验数据表明,每吨油中加入DODP—2(活性物含量20%质量)250g,可降低油井采出液凝点15℃,防蜡率可达52.8%。

The effect of pour point depressing and viscosity reducing to crude oil which led by pour point depressor would be severely influenced by the depressor's molecular configuration, additive quantity, active temperature, and shearing strength.And it also relates to the quality of crude oil including cere concentration, pectin concentration, carbon amount distribution and composition. For producing a kind of depressor suitable to Daqing crude oil, a pour point depressor (HJN 5#) mainly cousisting of an esterification...

The effect of pour point depressing and viscosity reducing to crude oil which led by pour point depressor would be severely influenced by the depressor's molecular configuration, additive quantity, active temperature, and shearing strength.And it also relates to the quality of crude oil including cere concentration, pectin concentration, carbon amount distribution and composition. For producing a kind of depressor suitable to Daqing crude oil, a pour point depressor (HJN 5#) mainly cousisting of an esterification product of styrene maleic anhydride copolymer(SMA) has been prepared, and the relationships between the pour point depressing effect and the impacting factors including depressor concentration, activation temperature ,and shear intensity have also been researched. In addition, by watching the variation of modality of cere crystalloid caused by adding depressor, the mechanism of pour point depressing and viscosity reducing were discussed. The results show that adding 0.2 wt% of HJN 5# could get 50% depression of pour point and more than 90% reduction of apparent viscosity of Daqing crude oil. The most suitable activation temperature of the depressor is 88 ℃.

降凝剂对原油的降凝减粘效果受其分子结构、使用剂量、活化温度及所受剪切强度的影响 ,并与原油的品质 (如 :蜡含量、胶质含量、碳数分布及组成等 )有着密切的关系 .为研制出适合大庆原油品质的降凝剂 ,合成了以苯乙烯 -马来酸酐共聚物 (SMA)的酯化物为主体的酯型降凝剂 (HJN -5#) ,并对其使用剂量、活化温度等参数进行了研究 ,还根据观察到的降凝剂使用前后原油中蜡晶形态的变化对降凝减粘作用机理进行了讨论 .结果表明 ,添加质量百分数为 0 .2 %的HJN -5#,可使大庆原油的倾点下降 50 % ,表观粘度下降 90 %以上 ,最佳活化温度为 88℃ .

With the degrading of petroleum quality and increasing of sulfur and metals content impurity in the non distillate oil, corrosion problem of the quenching ring in the gasifire has variously threatened the safely and stability of production,as the material of the quenching ring can not resist corrosion and corrosion fatigue when the temperature is over 1 000 ℃ It is possible to solve this problem by means of concealment of the quenching ring

随着原油品质的恶化 ,渣油中的硫及金属杂质含量增加 ,气化炉中激冷环的腐蚀问题已严重威胁了生产的安稳运行 ,其失效的原因是激冷环材料不能抗 1 0 0 0℃以上介质的腐蚀和腐蚀疲劳 ,用激冷环隐蔽技术解决该问题是可行的。
