- 摘要:
塔河油田油藏呈现“两超三高”(超深、超稠、高含胶质沥青质、高矿化度、高含硫化氢)特点,生产开发难度极大。塔河油田经过多年生产实践,在掺稀降黏技术的基础上,进行了多种井筒降黏技术工艺试验应用,但工艺应用后的经济效益尚不明晰。为了提高稠油油田开发项目经济性，加深对应用技术的科学认知,通过总结塔河油田井筒降黏技术特点,结合塔河油田生产一线数据对井筒降黏技术的应用效果进行对比分析,建立了一种以投入产出比为评价指标的经济效益评估模型,对塔河油田典型区块开展经济效益分析。分析结果表明，矿物绝缘电缆加热降黏以及水溶性化学药剂降黏、油溶性化学药剂降黏等工艺的应用效果和经济效益相对突出。研究结果对稠油高效开发具有一定价值。
Tahe Oilfield reservoir is characterized by“two super and three high”(super deep, super thick, high gum asphaltene, high salinity, high hydrogen sulfide), which makes production and development very difficult. After many years of production practice in Tahe Oilfield, several kinds of wellbore viscosity reduction technology have been tested and applied on the basis of dilution and viscosity reduction technology, but the economic benefits after application are still unclear. In order to improve the project economics of heavy oil field development projects and improve the scientific understanding of the applied technology, an economics evaluation model using the ratio of input versus output as the evaluation index was established to analyze the economic benefits on a typical block of Tahe Oilfield after the application of wellbore fluid viscosity reduction technology. This was done by comparing the characteristics of wellbore fluid after application of viscosity reduction technology with the frontline production data of Tahe Oilfield. Through the evaluation and discussion of the application effect and economic benefits of wellbore fluid viscosity reduction technology in Tahe Oilfield, it is shown that the application effect and economic benefits of heating using mineral insulated cable and watersoluble and oil-soluble chemical viscosity reduction are relatively significant. The study findings provide valuable references for the effective development of heavy oil reserves.
