新型水力泵排液工艺

酸化或压裂是改造油气层措施中常规的也是最有效的方法之一。问题是酸化或压裂结束后,采取何种工艺及时返排出残酸,减少残液二次沉淀对油层的污染。同时常规TCP(油管传输负压射孔)+DST(地层测试器)二联作测试工艺在遇到低压、低渗等非自喷油层时,要想取准油层产能、压力,收集到有代表性产液样品资料,困难很大。针对以上问题,大港油田钻采院研制了新型水力喷射泵,该泵可与酸化、压裂及射孔+测试等工艺配套使用,在实现一趟施工管柱同时完成几项工作的同时,利用喷射泵深抽、连续强排的技术特点,取得了较好效果。

Effect of organic dopants on electrodeposition and characteristics of polyaniline under the varying influence of H2SO4 and HClO4 electrolyte media

Electrodeposition of conducting polyaniline (Pani) was made under potentiostatic condition at pH 1.0 in different electrolyte media (H₂SO₄ and HClO₄) in the absence and presence of two organic dopants, disodium salts of naphthalene-1,5-disulphonic acid (NSA) and of catechol-3,5-disulphonic acid (CSA). The rate and yield of Pani deposition were dependent on the acid medium and the dopant employed. NSA in H₂SO₄ caused an increase in rate and yield but CSA decrease when compared to the rate and yield of H₂SO₄ alone. In HClO₄ medium, both the dopants showed a decrease. With regard to DC electrical conductivity, both the dopants exhibited an enhancement in H₂SO₄ medium but NSA a decline in HClO₄. Characterisation of the electrosynthesised polymer samples by various instrumental techniques (cyclic voltammetric: CV, FTIR, UV-Visible: UV-Vis, EPR, XRD, TGA and DTG methods) revealed that between the two acid media, H₂SO₄ was the better one. Further, it enlightened the role of two organic dopants in relation to the acid media. The advantageous role of NSA in H₂SO₄ had origin on its molecular characteristics such as non-polarity, larger π-electron cloud etc., while CSA could not perform such a role because of its easily oxidisable hydroxyl groups. In HClO₄, however, both the dopants could play only an unfavourable role owing to its greater polarity and oxidizing power than H₂SO₄.     

聚氨酯-聚丙烯酸酯共聚乳液的成膜和性能

通过XPS和接触角测试研究了聚氨酯-聚丙烯酸酯共聚乳液在不同基材上的成膜情况，并对共聚胶膜的耐水性和附着力进行了考察．由于该共聚乳液同时存在着亲水组分和疏水组分，所以它在不同的基材上成膜可导致其膜表面的组成成分不同，因而导致其耐水性和附着力也随基材而异。结果表明，亲水性的聚氨酯组分均富集于胶膜内部，但胶膜底层聚氨酯组分的含量却随基材的不同而不同。在憎水且表面张力较高的基材上，共聚胶膜的耐水性良好；共聚胶膜的附着力在表面张力较高的基材上也良好。
