|
摘要
针对四川盆地安岳气田磨溪区块龙王庙组气藏面临国内外无同类气藏开发经验借鉴、储层孔隙度低、非均质性强、应力敏感性强、中含H_2S、地层水侵等方面的挑战,研究总结了气藏开发中的管理优化与创新经验,探究其实现气藏的高质量、高效率、高效益开发的主要做法。研究结果表明:(1)技术与管理创新的融合实现了气田开发整体的高质量和高效益;(2)勘探开发一体化的实施实现了气田开发技术指标与整体指标的高水准;(3)"六化"模式的大力实施实现了地面工程建设的快速高质高效;(4)数字化气田建设成效显著,智慧气田显露锋芒;(5)高度重视环境保护,实现气田绿色清洁开发。结论认为:(1)技术创新是实现气藏高效开发的核心;(2)管理创新是实现勘探开发一体化的基础;(3)数字化气田建设是提升气田管理水平的有效途径;(4)坚持成本的有效控制是气田实现高效益开发的关键;(5)坚持严格的科学开发程序、建立完善的管理体制是实现气田长期稳产的重要保障。安岳气田龙王庙组气藏的高效开发可为国内外气藏的开发提供一定的经验借鉴与参考。
In Moxi block, Anyue gasfield, Sichuan Basin, most Longwangmiao gas reservoirs face many challenges, such as, no experiences learned from exploiting similar ones at home and abroad, low porosity, and strong heterogeneity, stress sensitivity, and formation-water invasion. Furthermore,there is much H_2S in these reservoirs. So, after a comprehensive study, some management, optimization, and innovative experiences on reservoir development were summed up, and many processes to realize high-quality, efficient, cost-effective development were explored. Results show (1) to conduct flat and professional management by means of optimizing organization structure during reservoir development,(2) to implement an integration of exploration and development via optimizing control mode,(3) to establish a six-nization mode, and to promote surface engineering construction,(4) to adopt advanced technologies, and to go ahead digital field construction, and (5) to optimize process element, and to create a QHSE control mode. It is found that technological innovation is the key to realize efficient development, management innovation is the basis to realize the integration of exploration and development, digital field construction is the effective means for promoting management level, valid cost control is the critical part to realize efficient development, and to keep strict and scientific development process and to establish perfect management system are the important guarantee for a long and stable development.
