摘要
目前我国大多数油田已进入以隐蔽油气藏为主的油气勘探阶段,在其烃源岩和构造和沉积相等成藏地质条件基本明确的情况下,通过成岩相的研究来优选优质储集体是该阶段油气勘探工作的重点和难点。但目前国内外关于储层成岩相的研究尚处于探索阶段,对于成岩相研究亟待解决的关键问题—利用测井资料将成岩相推到面上的研究更有待于加强。有鉴于此,基于国内外大量文献,对成岩相的影响因素、分类命名方案、测井识别原理和碎屑岩储层典型成岩相的测井响应特征进行系统调研和详细探讨。认为成岩相的测井识别方法最关键的是在储层岩性识别的基础上成岩作用类型和强度的定性判定以及成岩矿物含量的定量计算,并提出了利用蜘蛛网图测井识别成岩相的方法。最后对成岩相测井识别尚存在的问题进行探讨,并对成岩相测井识别方法未来趋势做出展望,以期能进一步推动成岩相测井识别相关方法的进展和加强成岩相在储集体预测中的应用。
Nowadays most of the oil and gas fields in china have come into the exploration and development stage of targeting the subtle oil and gas reservoirs, and for certain areas, the reservoir forming conditions such as source rock, tectonic and sedimentary facies are almost clear. Thus optimizing the high-quality reservoirs by the research of reservoir diagenetic facies is the emphasis and also the difficulty of petroleum exploration in this stage. But so far, the research of diagenetic facies still remains at an initial stage, and the key problem needed to be solved in the research of diagenetic facies is that recognition of diagenetic facies by logging data. Considering this, the controlling factors, division and naming schemes, logging identification principle of reservoir diagenetic facies are reviewed based on a large amount of literatures at home and abroad, and the logging response characteristics of diagenetic facies of typical clastic andcarbonate reservoirs are summarized. It is pointed out that the key points of logging identification method of diagenetic facies are identifying the lithology; determining the types and strength of diagenesis, and calculating the content of diagenetic minerals. The spider web diagram is put forward to briefly characterize the diagenetic facies. Lastly, the existing problems in the logging recognition of diagenetic facies are discussed in this article, and the future development of logging identification method of diagenetic facies is forecasted. This overview and introduction research on the preexisting researches on logging recognition method of diagenetic facies will promote the development of diagenetic facies and the application of diagenetic facies in predicting favorable reservoirs.
