老井复查技术在小断块油田的应用研究

The Application of Old Well Review Technology in Small Fault Block Oilfields

摘要: 老井复查是在充分利用现有各项资料的基础上，结合现代测井解释评价技术，对受当时技术条件限制而误判的储层进行重新认识，找出判断含油气的关键因素。老区H88小断块油田，油源充足，岩性、电性特征成为小断块判断是否含油的关键性因素，而储层物性影响相对缩小。在实际应用中取得了较好的开发效果和经济效益，达到了滚动增储和挖潜增效的双重目的。

Abstract: 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 oilfield 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 increase reserves and efficiency by rolling production.
