This article gives a brief description of development for overseas pumpingunits under present conditions. Although these units in various structures are still under development, and only small batches of them are produced, yet great potential of renewing has been possessed. We may use its experience for reference in developing pugmping units of new type.

本文简要介绍国外新型抽油机研究和生产现状。虽然这些形态结构各异的抽油机尚处于研制阶段,生产批量很小,但具有更新换代的潜力,可供我们研制新型抽油机时借鉴。

This paper studies the optimum formulation of petroleum sulfonate-oil-brine systems to obtain minimum interracial tension and maximum displacement effeci- ency.The solubilization parameters are enhanced from 10 to 14 by a application of new type of synthesized petroleum sulfonate,mixed with selected alcohols ele- ctrolytes.The interracial tension between microemulsion and oil or water is on the order of 10~(-3) dynes cm~(-1),nearly the same as the values obtained by a study group in Exxon production research company,The quantities of surfactants required are greatly reduced due to the enhancement of solubilization parameters. In order to obtain an optimum formulation of surfactant-oil-brine system, the effects of the average equivalent molecular weight of petroleum sulfonate, the chain length and amounts of alcohols as well as mixed alcohols and electr- olytes on the solubilization parameters,optimum salinity and the properties of low interfacial tension are studied separately. Experiments show that the solubilization parameters increase with chain length of alcohols and the optimal salinity decreases.When a kind of mixed alcohol and electrolyte is added,the low interfacial tension will occur in a wi- de range of salinity,therefore,the system is compatible with various formati- on waters. The oil displacement test show that oil recovery is increased by 30% and water cut is reduced from 98% to 50% under the condition of optimal salinity. When 0.2 PV of petroleum sulfonate-oil-brine system with 5% sulfonate conce- ntration is injected,oil recovery can be increased by 20%.

本文研究了产生最小界面张力的油-盐水-石油磺酸盐体系的最佳配方和驱油效率。通过合成新的石油磺酸盐和选择混合醇和混合电解质的实验,使增溶参数由10提高到14,该微乳液体系同油或水的界面张力达到10~(-3)达因/厘米,达到美国埃克森(Exxon)生产研究公司的研究指标。由于增溶参数的提高,大大地节省了表面活性剂的用量。为了获得油-盐水-表面活性剂体系最佳配方的关系,研究了石油磺酸盐的平均当量、醇的链长和用量以及混合醇和混合电解质对增溶参数、最佳含盐量和低界面张力性质的影响。实验表明,随着醇的链长增加,增溶参数增加,最佳含盐量降低。当加入混合醇和混合电解质时,可在较宽的含盐量范围内获得低张力,因此扩大了对地层水含盐量范围的适应性。驱油实验表明,在最佳含盐量的条件下,采收率可提高30%,含水率由98%降到50%。当注入0.2孔隙体积、石油磺酸盐的浓度为5%时,采收率可提高20%。
