刘祥重:区域重力波数域解释及找油效果,《石油地球物理勘探》,23(1)1988:110～118根据重力异常的频率随异常地质体埋藏深度而变化的原理,设计了数字滤波器,分离出不同深度的密度界面所产生的重力异常,供计算其埋藏深度。根据上述方法,选用 RT 地区1:20万实测区域重力资料进行试验,得出了如下结果:1.计算出中生界顶板埋深,古生界顶板埋深,沉积基底埋深,中生界厚度和古生界估算厚度;2.将实测布格异常分解为中生界异常、上古生界异常和下古生界异常;3.提取出局部异常。结果与已知资料对比及后来的钻井验证,证明比前人所有的方法有较好的地质效果。
Liu Xiangzhong: Interpretation of Regional Gravity Wave Number Domain and Oil Finding Effect, “Petroleum Geophysical Prospecting”, 23 (1) 1988: 110-118 According to the principle that the frequency of gravity anomaly varies with the buried depth of abnormal geological bodies, digital filters, Separate the gravity anomalies produced by the densities at different depths for the purpose of calculating the depth of their burial. According to the above method, 1: 200000 real-time measured gravity data in the RT area are selected for the experiment, and the following results are obtained: 1. Calculated the top depth of the Mesozoic, the depth of the top of the Paleozoic, the depth of the sedimentary basement, Mesozoic Thickness and thickness of the Paleozoic; 2. Decomposition of the measured Bougue anomaly into Mesozoic anomalies, Upper Paleozoic anomalies and Lower Paleozoic anomalies; 3. Extracting local anomalies. The results are compared with the known data and subsequent drilling verification to prove that the method has better geological effects than all the previous methods.
