| 摘 要： | 测井曲线是对所钻遇地层物性特征的直接反映，充分利用测井资料，有利于预测和识别古岩溶发育带。在构造背景分析基础上，依据古岩溶在钻井和测井上的显示，利用曲线组合对比方法，对财溶地层进行了测井相分析，得出“四低二高”的古岩溶识别标志。根据区域构造演化史提出岩溶演化模式，指出多期的构造旋回；复杂的断块欣斜作用和长期的化学活动性流体的溶蚀是研究区古岩溶发主育的主要因素。

| Abstract: | On the basis of tectonic-background analysis and drilling and log responses, electrofacies analyses were made on the paleokarstic strata in Xuhei-Chengbei terrace region. Criteria for recognizing paleokarst zones were established, and evolutionary pattern of karstification was determined based on the regional tectonic history. The main factors leading to the development of paleokarst in the region were found to be multi-phase tectonic cycle, complicated fault-block tilting and long-term dissolution by chemically active fluids. |
