摘要
生产井产能精细评价和高含水井产水来源成为目前油藏高效开发关注的重点,单一的PLT(production logging tool)、氧活化等流量测井技术手段往往受限于管柱结构和井产能,难以实现生产测井测试目的需求。噪声流量组合测井技术弥补了单一测试技术不足,能够获取套后产层精细产能贡献,解决分层封隔器密封性、水泥环窜漏等井筒完整性问题。组合测井技术应用在海上油田生产井动态监测中,探索了油井和气井噪声测井响应规律,明确了生产层产能低于油藏预期的原因,确定了产出流体来源,为后续增产、治理措施制定提供基础性依据,避免无效措施作业,降低生产作业成本。组合测井技术在海上生产井应用为区域油气藏潜能分析和生产井措施决策提供了重要的指导作用。
The precise evaluation of production well productivity and the source of water production from high water content wells have become the focus of current efficient oil reservoir development.Single flow logging techniques such as PLT(production logging tool)and oxygen activation are often limited by the structural of string and the well productivity,making it difficult to achieve the testing objectives and requirements of production logging.The combination logging technology of noise and flow has made up for the shortcomings of single testing technology,and can obtain the fine production capacity contribution of the post casing production layer,solve wellbore integrity problems such as the sealing performance of layered packers and cement ring leakage.The combination technology is applied in dynamic monitoring of production wells in offshore oil fields,explore the response law of oil well and gas well noise logging,identify the reasons why the production capacity of the production layer is lower than the expected,determine the source of production fluid,and provide a basic basis for subsequent production increase and treatment measures,avoid ineffective measures,and reduce production operation costs.The application of combination technology in offshore production wells provides important guidance for analyzing the potential of regional oil and gas reservoirs and making decisions on production well measures.
