【摘要】：FZ油田属断陷盆地典型的复杂小断块油田,断层多、断块破碎、目的层埋藏深。随着油田勘探开发不断地进行,出现了许多亟待解决的试井问题：压力动态监测资料很难正常的录取,层间干扰和井间干扰突出,严重地影响试井曲线形态特征,增加了资料分析的难度；不稳定试井、稳定试井和多井试井现场实施时涉及的地质及工艺设计条件难以掌握,容易出现施工周期长或录取的资料达不到测试目的等问题；传统的试井资料解释方法和解释结果存在一定的错误。通过研究分析试井技术和解释评价方法,结合油田实际情况,建立了油藏储集和储层渗流地质模型,将数值试井和生产数据分析技术成功应用于FZ油田PD1-32断块NgⅣ油藏早期勘探评价,分析储集体有效孔隙体积、边界距离和天然能量大小等,对后期开发方案及时调整起到了重要指导作用。开发过程中注水井压力连续测试资料在FZ油田PD1-32断块Ed1油藏动态分析中的成功应用,直观反映了连续测试试井资料在油藏开发过程中的重要作用,说明注水是必须按照动态数据分析结果进行调整,进一步体现了连续压力测试在油藏动态分析中的重要性和必要性。优化不稳定试井测试时间,缩短施工周期,提高试井资料录取品质,最终形成适合FZ复杂断块油藏的试井设计优化、资料录取和解释评价技术。
[Abstract]:FZ oilfield is a typical complex small fault block oilfield in the fault depression basin, with many faults, broken fault blocks and deep burial of the target layer. With the continuous exploration and development of oil fields, there are many problems to be solved in well testing: pressure dynamic monitoring data are difficult to obtain normally, interlayer interference and inter-well interference are prominent, which seriously affect the shape characteristics of well test curve. It increases the difficulty of data analysis, unstable well test, stable well test and multi-well test field, which are difficult to master the geological and technological design conditions, and are easy to appear long operation period or the data obtained can not reach the test purpose, and so on. There are some errors in the traditional well test data interpretation method and interpretation results. Through the research and analysis of well testing technology and interpretation and evaluation methods, combined with the actual situation of oil fields, a reservoir and reservoir percolation geological model is established. The numerical well testing and production data analysis techniques have been successfully applied to the early exploration and evaluation of PD1-32 fault block Ng 鈪，
