浅层超稠油油藏水平井开发合理技术政策研究
|
摘要
水平井是开发浅层超稠油油藏的有效技术,而开发技术政策对水平井合理部署和开发成败起着至关重要作用。针对九_(7+8)区油藏埋藏浅、厚度薄、非均质性强、原油粘度高、粘度差异大的特点,按照不同粘度分布特征,将L_(X+Y)区划分4个不同粘度区域,应用数值模拟方法研究了不同粘度区域的水平井蒸汽吞吐开发特点,对影响水平井蒸汽吞吐开发效果的地质参数、开发设计参数和注汽参数进行了敏感性分析和优化,确定了关键因素相关的技术界限及合理的开发设计参数和注汽参数,为油层措施挖潜、提高油藏最终采收率及下一步水平井加密、开发方式的有效转换提供决策依据。
The horizontal well is an effective technique for the development of super heavy oil reservoir,the development technology policy plays a vital role in reasonable deployment and development of horizontal wells.According to the shallow buried depth,thinness,strong heterogeneity,high oil viscosity,viscosity variation characteristics of LX+Y reservoir,according to different viscosity distribution,LX+Y is put into 4 different viscosity region,then steam huff and puff development characteristics of horizontal well in different viscosity region are studied by using numerical simulation method;geological parameters,design parameters and steam injection parameters that influence cyclic steam stimulation effect of horizontal well were analyzed;key factors related to technical limits and reasonable design parameters and steam injection parameters are determined,which provides basis for decision making and effective development mode for digging potential reservoir measures,for improving the oil recovery and for the next step to encrypt the horizontal wells and the effective conversion of development mode.
