本文是对现场实验的实际情况的研究,打算确定是否可以用抑制注水井井筒附近产生H2S细菌生长的方法来控制油层进一步变酸。用16m3漂白液浸泡三口污水回注井20h.在侵泡之前40天和浸泡后六个月之内,对现场井网中对应的生产井监测其产生的H2S,量。此外,作为对照,同时监测另一个未浸泡的现场井网的H2S产量。由于得到了不确定的给果。所以不能确定漂白剂的杀菌作用。在被检测的17口实验生产井中,有六口井显示出H2S产量下降,虽然降低幅度很小。在对照井中未检测出H2S产量下降)在模拟的油层条件下发生了原油被漂白液氯化的现象,但氯化程度很低。未从与漂白液接触的产出油中检出氯化的烃来。
This article is a study of the field experiments to determine if further oil souring can be controlled by inhibiting the growth of H2S bacteria near the wellbore. Soak the three sewage injection wells 20h with 16m3 of bleach solution, and monitor the H2S production of the corresponding well in the well pattern within 40 days before soaking and within six months after soaking. In addition, as a control, H2S production from another un-soaked in-place well pattern was simultaneously monitored. Because of the uncertainty given to the fruit. So can not determine the bactericidal effect of bleach. Of the 17 pilot production wells tested, six wells showed a decrease in H2S production, albeit with a small decrease. No decrease in H2S production was detected in the control wells.) Crude oil was chlorinated by the bleach solution under simulated reservoir conditions, but the degree of chlorination was low. Chlorinated hydrocarbons were not detected from the produced oil in contact with bleach.
