地质条件约束地质建模在LD27-2油田东营组随钻地质建模中的应用
|
摘要
地震资料约束和地质条件约束是渤海海域油田稀井网条件下提高地质模型精度的重要依据。LD27-2油田东营组地震资料品质差,无法满足地质建模井间储层预测的精度要求,因此在随钻地质建模过程中采取了"充分发掘地质建模软件的综合研究平台作用,加强基于地质建模软件的随钻综合地质研究,然后用不断更新的地质研究成果约束随钻地质建模过程"的随钻建模方法。实践证明,该方法不仅为LD27-2油田东营组随钻地质建模的顺利完成提供了有力支持,也为渤海海域类似油田的随钻工作提供有益借鉴。
Seismic data and geological constrain was important basis of enhancing the accuracy of the geological modeling under sparse well patterns conditions in Bohai Bay Oilfield.The seismic data quality of Dongying Formation in LD 27-2 Oilfield was poor,and could not meet the accuracy requirements to predict reservoirs for geological modeling.Therefore,a new geological modeling method was used in drilling,the method was to fully explore the geological modeling software platform for comprehensive research,and to strengthen comprehensive research while drilling based on the geological modeling software to continue the drilling geological modeling process under more constrained geological condition.Practice proves that this method is not only useful for the drilling geological modeling,but also provides strong support for the drilling geological modeling similar to LD 27-2 Oilfield in Bohai Sea Oilfield.
