大港油田孔店采油污水排放处理的研究

大港油田孔店污水站部分污水含有大量的油、固体悬浮物和其他物质,原处理工艺除油和固体悬浮物有一定的效果。但ＣＯＤｃｒ等主要指标都没有达到国家排放标准。在此基础上提出了在原流程中加入调整剂并使污水达标排放的经济可行的处理方法,且即将投入现场运行。     

弱碱型三元复合驱采出水的流变性变化规律

通过旋转黏度计测试黏弹性和视黏度,研究了三元(碱、表面活性剂、聚合物)复合驱采出水的流变性。结果表明,三元复合驱采出水的黏弹性可用Maxwell线性黏弹性模型描述。其视黏度和黏弹性主要取决于所含聚合物的相对分子质量和含量,并且随聚合物含量的增加而增大。低聚合物含量三元复合驱采出水的视黏度和黏弹性模量之间存在着G=1．6736μ1.8155的关系式。

Microstructure and corrosion performance of X100 steel in the oilfield produced water

ABSTRACT

The corrosion performances of X100 steels in the oilfield produced water with different temperature (30°C, 40°C, 60°C) under the simulated working conditions were studied by potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) test. Energy dispersive spectroscopy (EDS) was used to measure the element composition of the sample after corrosion. The phase and chemical compositions of the specimens were analyzed by X-ray diffraction (XRD) and Raman spectrometry. The electrochemical results showed that the corrosion resistance of the specimen exposed for 24 hours increased with the increase of the testing temperature, indicating the better protective effect due to the corrosion product film formed under high temperature despite the impact of turbulence. The corrosion products consist of Fe₃O₄, Fe₂O₃, α-FeOOH, and γ-FeOOH. The corrosion mechanism model of X100 steel was established and the corrosion behavior was analyzed under simulated working conditions.     

CHATACTERIZNTIAN OF SOME IRAQI ASPHALTS. II. NEW FINDINGS ON THE PHYSICAL NATURE OF ASPHALTENES

ABSTRACT

Uapcur pressure csmometry (UPO) and viscometric technique were used to reveal the true molecular weight of asphaltenes and the degree of association in solvent of different polarities at different temperatures. The number average malecular weight of unassociated asphaltenes was found to be 935 g/mcl. In n' trobenzene at 120 C. The degrees of association were determined from UPO in benzene at 37, 45, 60 C, in chlorobunzene at 37, 45, 60 and 90 C. in THE at 37, 45, 60 C and in nitrobenzene at 90 C. The degree of association determined by ulscometric method at 37, 45 and 60 C, in these soluents were found to be in approximate agrement with that found bv UPO. Data derived by means of ulscometric and osmometric methods consolidated the recognition that asphaltenes could be similar to macro-molecules structurally.
