方法 依据油藏非均质性严重、天然能量低、高含硫、油稠、胶结疏松、易出砂、井斜等特点 ,开发过程中采取了降粘、防腐、注水、防砂等一系列有针对性的配套技术。目的 解决开采过程中出现的难题。结果 区域内油井平均检泵周期6 84d ,最长的油井检泵周期达 1178d ,原油粘度平均下降 87 3% ,区域内已累积产油 16 9× 10 4 t,累积注水 6 3× 10 4 m3 ,取得了明显的开发效果。结论 该油藏的开发成功 ,为全面动用区域内地质储量奠定了基础 ;为同类油藏的开发提供了可借鉴经验。
Methods Based on the characteristics of serious reservoir heterogeneity, low natural energy, high sulfur content, thick oil, loose cement, easy sand production and well inclination, a series of methods of viscosity reduction, anticorrosion, water injection and sand control were adopted in the development process Targeted supporting technology. Objective To solve the problems in the mining process. As a result, the average well inspection interval was 6 84 days, the longest period of inspection of oil wells was 1178 days, the average viscosity of crude oil decreased 87 3%, the accumulated oil production was 16 9 × 10 4 t and the cumulative water injection was 6 3 × 10 4 m3 , Has achieved significant development results. Conclusion The successful development of this reservoir has laid the foundation for the comprehensive utilization of geological reserves in the region and provided experiences for the development of similar reservoirs.
