前七章为鉴别注水和含油污水处理中常见的问题提供了可靠的根据。附录2“注水故障检测步骤”,仅是在对故障的性质及其产生的原因几乎一无所知时,作为鉴别故障的一般指导。如果腐蚀不特别严重,则缺乏经验的现场人员易把结垢当成腐蚀,或者把沉积的大量固体物叫做石膏。这些都是可以理解的,因为没有把原因弄清楚。组份复杂的沉积物的堵塞,有时是基于几种原因。它比单纯的结垢和腐蚀更难于解释。不管怎样,绝大多数现场工程师都应研究运转中的主要问题并计算运转费用等。可是,在一般情况下,由于不十分熟悉地下情况,所以,需要深入具体地进行调查研究。
The first seven chapters provide a reliable basis for identifying common problems in waterflooding and oily wastewater treatment. Appendix 2, “Water Filling Fault Detection Procedures,” is a general guide to identifying faults only if they have little or no knowledge of the nature of the fault and the cause of the fault. If corrosion is not particularly severe, inexperienced field personnel can easily use scaling as corrosion or deposit large quantities of solids called gypsum. These are understandable because the reason is not clarified. The clogging of components with complex deposits is sometimes based on several reasons. It is more difficult to explain than pure scaling and corrosion. In any case, most field engineers should study the main problems in operation and calculate operating costs. However, under normal circumstances, due to not being very familiar with underground conditions, there is a need to conduct in-depth and detailed investigations and studies.
