本文介绍了星座图的作图步骤和计算方法,并对近三年来斯仑贝谢公司在中原油田测的45口井的311层点(试油的249层点,未试油的水层62层点),运用星座图进行了分析,解释符合率是令人满意的。本方法对中原油田细粉砂复杂岩性的解释,是行之有效的,并具有快速、直观的特点。 This paper introduces the steps of constellation drawing and the calculation methods. In the past three years, the 311 points of 45 wells measured by Schlumberger in Zhongyuan Oilfield (249 layers of test oil and 62 Layer point), the use of constellations were analyzed to explain the coincidence rate is satisfactory. The method of Zhongyuan oilfield fine silt complex lithology interpretation is effective, and has a fast, intuitive features.
