【摘要】：曙一区超稠油开发到今天,地下矛盾尖锐复杂,稳产难度越来越大,制约了企业的持续稳定发展,认真组织实验,加强瓶颈技术的研究势在必行,以有效提高超稠油油藏开发水平。论文应用物理模拟、数值模拟方法,通过详细的现场实验及应用,开展了低碳有机酸解堵技术、高温防砂工艺,氮气泡沫凝胶调剖助排技术、选配注工艺,套损井选配注管柱工艺、套变井可掺洗机械堵水管柱、套损井小外径抽油泵,改进完善水平井分段注汽技术、水平井出水治理工艺、水平井强化采油技术的研究。有针对性的解决了超稠热采中影响采收的四大突出问题,分别是:部分区域动用程度低,开发效果不理想;中高轮次油气生产井地层能量低,汽窜严重;套损井比例高,井况问题制约油气生产井产能发挥;水平井开发矛盾突出,配套技术不完善。通过对论文中研发的新技术和工艺的实践,证明这些技术及工艺达到了提高超稠油蒸汽吞吐开采水平和实现兴隆台油藏高效开发的目的,为该类油藏的热采开发提供了有效依据。
[Abstract]:With the development of super heavy oil in Shu 1 area today, the underground contradiction is sharp and complex, the steady production is more and more difficult, which restricts the sustainable and stable development of enterprises. It is imperative to organize experiments seriously and strengthen the research of bottleneck technology. In order to effectively improve the development level of super heavy oil reservoir, this paper applies physical simulation and numerical simulation methods, through detailed field experiments and applications, develops low carbon organic acid plugging removal technology, high temperature sand control technology, nitrogen foam gel profile control and drainage technology. Selection and injection technology, casing damage well selection and injection string technology, casing variable well can be mixed washing machine water shutoff string, casing damage well small outer diameter pumping pump, improve horizontal well subsection steam injection technology, horizontal well water treatment technology, Research on enhanced oil recovery technology in horizontal wells. Four prominent problems that affect recovery in ultra-thick thermal recovery are solved. They are: low production degree in some areas, unsatisfactory development effect, low formation energy in medium and high round oil and gas production wells, The steam channeling is serious, the proportion of casing damage wells is high, well condition problems restrict the production capacity of oil and gas production wells, the contradiction of horizontal well development is prominent, the supporting technology is not perfect. Through the practice of the new technology and technology developed in this paper, It is proved that these technologies and techniques can improve the production level of super heavy oil and realize the high efficiency development of Xinglongtai reservoir and provide an effective basis for the thermal recovery and development of this kind of reservoir.
