根据东海西湖凹陷地质特点,研制了测井自动评价地层的计算方法,该方法在钻遇地层中能自动追索地震反射界面、划分地层,识别测井相,对钻遇地层中烃源岩有机质丰度和含油气储集层的产能特征进行自动评价。用测井自动评价地层方法对西湖凹陷苏堤构造带的残雪构造的三口井进行了综合评价。

According to the geological property of Xihu Trough in the East China Sea, to investigate and set up the calculating method of using logging data strata automatically. Based on the method, to trace after reflection boundary, to calssify strata, to identify electrofacies, and to evaluate automatically abundance of organic matter in hydrocarbon source rock and productivity property in oil and gas bearing reservoir in drilling strata. By the method of using logging data to evaluate strata automatically synthetically the strata of the three wells of Canxue Structure of Sudi Structural Belt in Xihu Trough.
