摘要
西湖凹陷在油气勘探中首选气测录井技术作为常规录井方法,同时对该地区进行气测录井参数与地面储量的关系研究,旨在尝试气测解释评价方法的创新。为此以全烃数据为依据,利用烃含量理论公式计算地面含气量,并推导出不同钻头直径下气测全烃与地面含气量的经验公式,进而建立西湖凹陷的地面含气量储集层解释评价方法及标准。在后期勘探解释应用中收到的良好评价效果表明,该方法可成为气测录井技术在气层解释评价中一种新的技术手段。
The first choice of gas logging technology is used as a conventional logging method in oil and gas exploration of Xihu depression.At the same time,a study of gas logging technology is carried out based on the fluid properties of gas reservoir to try to innovate the method of gas logging interpretation and evaluation.Therefore,based on the total hydrocarbon data,the surface gas content is calculated by using the theoretical formula of hydrocarbon content.The empirical formula of gas logging total hydrocarbon and surface gas content under different bit diameters is derived.Then the interpretation and evaluation method and criteria of surface gas bearing reservoir in Xihu depression are established.The good evaluation results received in the later exploration and interpretation indicate that this method can be a new technical means for gas logging technology in gas reservoir interpretation and evaluation.
