【摘要】 该论文所依托的项目是以航磁资料处理解释为主(结合重力、电法、地面地质、钻井和少量地震资料)、以连片编图为基础、以石油勘探部署为目标的大型综合研究项目。工作地区为中国石油化工股份有限公司东北新区,包括二连盆地北部、二连盆地南部、松辽盆地北部、松辽盆地南部、泛三江盆地五个区块勘探工作。论文所用技术系列主要包括位场定性处理、定量处理和综合地质解释三个方面。其中富有新意、使用频繁、效果显著、为本论文所独创的处理技术是:1、在重磁异常优选延拓技术的基础上,发展而成的优化滤波处理技术。2、提出一种应用航磁异常半定量解释磁性体埋藏深度方法:磁异常全梯度模磁性体顶面深度标定方法。借助于以上技术系列与独创技术,本报告在对中石化东北新区内的断裂系统、基底结构、火成岩和构造单元划分等基础地质问题进行深入研究的基础上,分区块对中石化东北新区进行了油气远景评价,明确指出:1、应重点突破的凹陷:莽汉凹陷、赛汗塔拉凹陷、宾县凹陷、布日墩凹陷南凹槽、昌图凹陷、四方台凹陷和挠力河凹陷等。其中,须重点关注的局部构造有:茫汉凹陷南部的沙尔好来构造、昌图凹陷北部曲家店构造、四方台凹陷中部大房身构造和宾县断陷中部的刘一斌屯北构造。2、应放弃的区块或区段:二连盆地南部尕顺凹陷西北部特默图一带、卫井凹陷与十格木凹陷之间乌尔图一带的登记区块;二连盆地北部西乌珠穆沁旗布日敦一带、巴音都兰南部一带的登记区块;松辽盆地北部、泛三江盆地的完达山褶皱带、双鸭山隆起、小兴安岭褶皱带沾河地垒、松辽盆地西部斜坡区嫩江-讷河连线以西隆起带上的登记区块;松辽盆地南部的奈曼旗西乌丹营子一带、库伦旗北额勒顺镇一带、双辽县南金宝屯镇一带、彰武县东南公主屯镇一带、通榆西高力板镇一带的登记区块或区段。3、应扩大登记范围的区块和抢先登记的区带:二连盆地南部的查干诺尔凹陷、卫井凹陷南缘、伊和乌苏凹陷、吉托勒凹陷东延部分;二连盆地北部玛拉吉勒音其格凹陷;松辽盆地南部的甘旗卡断陷北延部分、铁法市西三家子断陷、白音花北玛尼营子凹陷、道劳杜凹陷西缘、奈曼旗西南罗家沟断陷西延部分;松辽盆地北部铁力凹陷东延部分。更多还原

【Abstract】 The thesis presents an integrated interpretation mainly from aeromagnetic data cooperatedwith gravity, electrical, drilling and seismic data, and geological maps, using aeromagneticand gravity maps compiled by the author. The interpretation has been applied to oil and gasexploration in less-known frontier area in northeast China. The methods used for thisinterpretation include qualitative and quantitative processing of potential data, and integratedgeological inference.The thesis proposes the following two new and effective data processing methods used forthis interpretation:1. Preferential filtering modified and improved based on preferential continuation forpotential field separation.2. Estimation of depth to top of magnetized bodies from module of total gradient forsemi-quantitative interpretation of aeromagnetic anomalies.The thesis studies fault system, basement structures and division of structural units from theabove methods. Based on these studies prospective oil and gas areas in less-know frontierarea in northeast China conducted by SINOPEC has been evaluated, including the followingkey points:1. The depressions for focal exploration: Manghan depression and the others. The localstructures for focal exploration: Shaerhaolai structure in the Manghan depression and theothers.2. The previous prospective area(s) should be abandoned: Temotu area in the Erlian basinand the others.3. The area(s) should be registered extensively and immediately: Chagannuoer depressionin the Erlian basin.更多还原
