摘要

本研究的目的是分析OXNARD石油礦區裡三口生產油井（M-1、M-5及M-7號井）的普通電測資料，從事地層對比，以評估油氣蘊藏潛能。其中，各井的電測資料中僅包含自然電信差及電阻資料以供做分析。地層對比時，利用M-1號井的已知石油生產層資料為控制點，而與其鄰近井之電測資料作對比。其中主要是利用了topanga地中的TS 1及TS 2生產層的電測曲線趨勢來做對比。並由分析各個電測資料的結果顯示：在M-5號井深度為5459呎至5499呎之砂岩層區間中有油氣儲存跡象。

The purpose of this case study is to evaluate hydrocarbon potential for the M-lease in the OX-field by using conventional electrical well logs. The M-1, M-5, and M-7 well electrical logs, which include only spontaneous-potential (SP) and conventional resistivity logs, are used to derive formation correlations and hydrocarbon potential for the M-lease. M-lease formation correlation starts from the M-1 well which was tested for several reservoirs and produced from the Topanga Formation (5789 ft to 5834 ft) and the Sespe Formation (6049 ft to 6270 ft). The well log characteristics of the Topanga TS 1 and TS 2 producing reservoirs are used exclusively in formation correlation for producing zones in the Topanga Formation. Results from this study indicate that hydrocarbon potential zone exists at 5459 ft to 5499 ft depth near the M-5 well.
