- 摘要:
大宁—吉县区块致密气藏至2019年已经过了5年开发历程,在区块早期开发阶段,开发单位针对致密气井场所有可能出现的工况采用了较为全面的工艺模式，结合近5年实际生产运行情况,大宁—吉县区块致密气井场工艺流程暴露出了生产设备冗余、运行成本较高等不足。为此，对大宁—吉县区块已建致密气井生产数据进行了统计分析,为致密气井场工艺流程的优化简化提供了佐证,实现致密气井场各工艺单元的灵活调整,进一步提升致密气井场工艺与生产运行需求的适应性。研究结果为降低井场后期生产运行成本提供了思路。
Daning-Jixian County Tight Gas Block reservoir has been under development for 5 years. In the early development phase of the block, the development company adopted a comprehensive process model taking into account all the possible operating conditions at the tight gas well site. Based on the actual production operation conditions in the last 5 years, the well site process flow scheme of Daning-Jixian County Tight Gas Block exposes the short coming of oversized production equipment and high operating cost. In this study, the production data of the existing tight gas wells in Daning-Jixian County Block were statistically analyzed, which provides evidence for the optimization and simplification of the tight gas well field process flow scheme, and enables the flexible adjustment of each process unit in the tight gas well site. In addition, the improved adaptability of tight gas well site process units can further enhance the ability to meet the changing production and operation requirements. This study provides insights into lowering the production operation cost in the late development phase of the tight gas well site.
