摘要(Abstract)：

为了研究海拉尔盆地贝尔凹陷H_1断裂处南屯组二段（南二段）油气分布特征，在泥岩盖层内断裂渗漏油气机制及其能力影响因素研究的基础上，利用泥岩盖层内断裂埋深、倾角、填充物泥质含量、断距和泥岩盖层厚度，建立了一套泥岩盖层内断裂渗漏油气能力分布特征研究方法，用其研究大磨拐河组一段（大一段）下部泥岩盖层内H_1断裂渗漏油气能力。结果表明：测点1―3、5、8、13、15处大一段下部泥岩盖层H_1断裂不渗漏，测点7、9―12、14处大一段下部泥岩盖层内H_1断裂渗漏油气能力相对较弱，有利于油气在南二段内油气聚集与保存，目前油气钻探在测点7、12、14处见到了油气显示；测点1―3、5、8―11、13处和15处南二段未见到油气显示，是由于位于构造低部位、油气供给不足或砂体不发育造成的；测点4、6处大一段下部泥岩盖层内H_1断裂渗漏油气能力相对较强，不利于油气在南二段内聚集与保存，目前测点4、6处南二段油气钻探未见到油气显示。研究成果对指导海拉尔盆地贝尔凹陷H_1断裂处南二段油气勘探方向具有实用价值。
In order to study distribution characteristics of oil and gas in the second member of Nantun Formation (K_1n_2) of H_1 fault in Beier sag of Hailar Basin, based on the research on the mechanism of oil and gas leakage of faults in mudstone caprock and influencing factors of its capacity, a set of methods are established to study distribution characteristics of oil and gas leakage capacity of faults in mudstone caprock by using buried depth, dip angle, argillaceous content of fillers, fault throw and thickness of mudstone caprock. These methods are used to study oil and gas leakage capacity of H_1 fault in mudstone caprock of lower part of the first member of Damoguaihe Formation(K_1d_1). The results show that, at measuring points 1-3, 5, 8, 13 and 15, H_1 fault in mudstone caprock of lower part of K_1d_1 has no leakage; at measuring points 7, 9-12 and 14, oil and gas leakage capacity of H_1 fault in mudstone caprock of lower part of K_1d_1 is relatively small, which is conducive to the accumulation and preservation of oil and gas in K_1n_2. At present, oil and gas shows have been observed at measuring points 7, 12 and 14 in oil and gas drilling. No oil and gas shows in K_1n_2 at measuring points 1-3, 5, 8-11, 13 and 15, which is due to the low structural position, insufficient oil and gas supply or undeveloped sand bodies. At measuring points 4 and 6, oil and gas leakage capacity of H_1 fault in mudstone caprock of lower part of K_1d_1 is relatively large, which is not conducive to accumulation and preservation of oil and gas in tK_1n_2. At present, no oil and gas shows in the second member of Nantun Formation at measuring points 4 and 6 in oil and gas drilling. The research provides practical value for guiding oil and gas exploration direction of K_1n_2 at H_1 fault in Beier sag of Hailar Basin.
