精细油藏描述技术在哈萨克斯坦阿雷斯油田的应用
|
摘要
在三维地震资料重新解释的基础上,针对哈萨克斯坦阿雷斯油田构造复杂、油水关系复杂、开发难度大的特点,开展精细油藏描述研究,搞清了地层结构和地层层序,深化了对断层的认识,使主力油层的构造得到完全落实;建立了流体分布模型,并基于构造、沉积、储层新认识发现了低阻油层,使油田的地质储量得到进一步落实,为开发方案的编制、科学合理地开发奠定了基础。同时,通过储层反演,预测了储层砂体分布,为优化井位及钻井设计提供了可靠依据,全年部署直井7口、水平井3口,取得了显著效果。实践证明,精细油藏描述工作具有重要意义,它可以为合理开发油(气)藏制定开发战略和技术措施提供必要的和可靠的地质依据。
As Aleisi Oilfield features in complex structure,complicated oil-water relationship,and difficult development,research is conduct on fine reservoir description,based on reinterpretation of 3D seismic data.This helps to clearly show structure and sequence of formations and deepen understandings of faults,which enables structure of major reservoirs to be completely determined.Fluid distribution model is established.Low resistivity reservoirs are discovered on the basis of new understandings of structure,deposits,and reservoirs and it enables the geological reserves of the oilfield to be determined and offers a solid basis for development plans design and scientific and reasonable development.Meanwhile,distribution of reservoir sand bodies is predicted based on reservoir inversion,providing sound foundation for the optimization of well location and drilling design.Seven vertical wells and three horizontal wells are deployed in the whole year of 2007,which leads to remarkable results.Practice shows that it is significant to conduct fine reservoir description,which can provide necessary and reliable geological bases for reasonable development of hydrocarbon reservoirs and the establishment of development strategies and technical measures.
