Old well review was based on making full use of existing information, combined with modern logging interpretation and evaluation techniques, the misjudged reservoirs caused by the restriction of technical conditions at that time were re-realized, the key factors for oil and gas judgment were found out. In H88 small fault oilfleld of an old block, the oil source was abundant, and the characters of lithology and electrical property were the factors for judging if the faulted zone contains oil, while the influence of the reservoir property was relatively reduced. In practical application, it achieves better development effect and economic benefit, which achieves the dual purposes of in- crease reserves and efficiency by rolling production.
