哥伦比亚ABARCO油田开发方式

Abstract

通过对哥伦比亚ABARCO油田蒸汽吞吐开发效果的评价，论证ABARCO油田的开发潜力所在，为MECL公司合同到期是否进行延期提供了依据。研究过程利用了MECL公司现有的数模体，并对模型进行了修正，对该油田开发的历史数据进行了拟合，对前期蒸汽吞吐的效果进行模拟和评价，开展了油田开发潜力的挖潜深入研究，提出了油田下一步进行后续开发的潜力和效果。目前油田通过蒸汽吞吐开发效果较好，同时通过蒸汽吞吐和蒸汽驱开发方式进行深入研究对比。应用数值模拟方法选取典型区块进行蒸汽驱效果分析并与蒸汽吞吐进行比较。通过对比分析表明该油田以蒸汽吞吐开发的效果相对较好，建议下步采用的主要开发方式仍以蒸汽吞吐为主而不急于转为蒸汽驱开发方式，蒸汽驱只是作为下一步可能替代的开发方式，为油田下一步的开发提供了方向，为油田是否进行延期提供了一定的客观依据。 The development potential of ABARCO field is demonstrated by the evaluation of the steam stim-ulation effect in the ABARCO field in Colombia, which provides the basis for the extension of the MECL contract. The research process uses MECL’s existing number of motifs; the model is modified; the historical data of the oilfield development are fitted to simulate and evaluate the effect of the previous steam stimulation; the potential of oilfield development is deeply researched; and the potential and effect of the next step in the development of oilfield are put forward. At present, the development of oil field through steam stimulation is good, and the steam stimulation and steam flooding development methods are in deep study and comparison. The numerical simulation method is used to select the typical block for steam flooding and compare with steam stimulation. The comparative analysis shows that the development effect of steam stimulation is relatively better. It is recommended that the main development mode used in the next step is still the steam stimulation but not the steam drive, which only may be the alternative development mode in the next step. In the future development of oil field, this paper provides a direction and a certain objective basis for the possible delay.
