新项目评价中快速地质建模方法探讨——以X区块新项目评价为例
|
摘要
结合新项目评价的特点,就评价过程中地质建模技术展开讨论,以便为新项目评价中快速地质建模提供借鉴。建模过程充分利用现有的地震与测井资料,综合构造、沉积、储量参数等地质资料,结合相控建模技术,充分发挥随机模拟的优势,开展快速高效地质建模工作,进行储量计算并开展储量不确定性评价。将二维储量计算所采用的油层厚度图这一重要基础资料用来约束模拟过程,确保模型计算的地质储量与二维计算结果具有一定相关性,从而为新项目最终决策提供可靠依据。
The task for project evaluation in a short time increased rapidly owing to the going-out oil and gas strategy of CNPC.Researchers were increasingly demanded for evaluating the project to be purchased efficiently and professionally.The geological modeling technique was discussed according to the characteristics of the new project evaluation,a reference was provided for rapid geological modeling.The geological modeling fully used the available seismic and logging data,and in combination with geological data including structure,deposition,OOIP calculating parameters,and integrating with facies-constrained modeling techniques,thus to bring the advantages of stochastic modeling into full play,rapid and efficient geological modeling was carried out for calculating OOIP and evaluating its uncertainty.The research ideas can introduce the oil thickness map-core of 2DOOIP calculation to constrain the modeling,and ensure a certain correlation between two methods for calculating OOIP,finally,it provides a reliable basis for final decision of the new project.
