摘要:针对ABC油田在特高含水阶段开发中出现的地层脱气、油水井套损等间题,以吸水与采液指数变化规律为依据,在注采压力和注采比等指标技术界限研究基础上,提出并建立了基于水并端和油井端生产能力的采液速度技术界限的测算方法,以“以注定采”为原则确定油田整个注采系统的采液速度技术界限。结果表明:基于水井端的采液速度技术界限低于油井端的采液速度技术界限,这也进一步证实了特高含水阶段实施“以注定采”的必要性。提出的研究方法和得到的结论对特高含水油田开发理论研究和实际应用具有重要的参考价值。关键词:特高含水;以注定采;采液速度;技术界限

Abstract: In the light of the problems of the stratigraphic degassing, oil and water well casing danage and so forth at the extra-high watercut stage of Oilfield ABC, development, according to the changed laws of the water suction and liquid production index, on the bases of the researches on the technical limits of the injection-production pres sure, injection-production ratio and so on, the testing and calculating method was established on the bases of the technical limits of the liquid production rate of the productivities at the ends of the water and oil wells, the technica limit of the liquid production rate for the whole injection-production system was determined by the principle of production determined by the injection", The achievements show that for the limits stated above, the injectors' are lower than those of the producers, thus the necessity of the principle operation is also further verified at the extra high watercut stage. All the presented studying approaches and achieved conclusions possess important reference value for the theoretical researches and practical application of the extra-high watercut oilfield development
Key words: extra-high water cut; production determined by the injection; liquid production velocity; technical limit
