【摘要】：随着油气田开发进程的不断推进,很多油田会出现诸多影响稳产高产的因素。本文在整理分析大量生产数据的基础上,针对西峰油田Z区块长8储层,进行精细油藏描述,建立三维地质模型,并且进行动态数值模拟,优选开发配套指标。通过油藏工程研究,提出合理的开发技术政策与调整方案。经过学习研究得出,将长8储层划分为12个单层,主力层分布在中部层位,主要砂体类型为水下分流河道,物性较好。通过对井网的分析得出,菱形反九点井网开发效果较好,同时明确各井网见水见效模式。针对不同原因,对部分井提出补孔或堵水调剖措施,并建议采取各井网分区开发方式,最后对优选的开发方案进行预测,结果显示可使采出程度提高4.17%,方案可行性较强。
[Abstract]:With the continuous development of oil and gas fields, many oil fields will have many factors that affect the stable production and high yield. Based on the analysis of a large number of production data, this paper aims at Chang 8 reservoir in Z block of Xifeng Oilfield. Fine reservoir description, three-dimensional geological model, and dynamic numerical simulation, optimal selection of development indicators. Through reservoir engineering research. Through study and study, the Chang 8 reservoir is divided into 12 single layers, the main layer is distributed in the middle layer, the main sand body type is underwater distributary channel. Through the analysis of well pattern, it is concluded that the development effect of rhomboid inverse nine-spot well pattern is better, and the pattern of water seeing effect of each well pattern is clear. According to different reasons, some wells are put forward some measures of hole filling or water plugging and profile control. It is suggested that each well pattern should be developed in different areas, and finally the optimal development scheme should be predicted. The result shows that the recovery degree can be increased by 4.17%, and the scheme is feasible.
