谐振法油气检测技术在致密砂岩气藏中的应用——以苏10区块为例

Application of Resonance Method Hydrocarbon Detection Technology to Tight Sandstone Gas Reservoirs - Taking Su-10 block as an Example

谐振法油气藏检测技术是一种呼应式直接寻找油气的方法，该技术从介质振动理论出发，利用激振力和介质发生共振采寻找油气。理论认为，油气储层固有频率在0-15Hz之间，根据地震波与油气储层的共振频率来确定油气的分布情况。该方法只需要地震资料，具有实用性广、成功率高等特点。苏里格气田苏10区块主要舍气层系为上古生界二叠系山西组山1段和石盒子组的盒8段，目的层物性较差，属于典型的致密砂岩气藏。以苏10区块为例．说明谐振法油气藏检测技术在致密砂岩气藏中的应用情况。结果表明，谐振法油气检测技术适合于致密砂岩气藏．得出的气藏分布图为研究区下一步井位部署提供了可靠的地质依据、

The resonance-method hydrocarbon reservoir detection technology is an echo-mode direct method of exploring for oil and gas. Proceeding from the media vibration theory, the technology is to find oil and gas through the resonance of exciting force and me- dia. The theory suggests that the natural frequency of the oil and gas reservoirs is between 0 - 15 Hz. The distribution of oil and gas is determined by the resonance frequencies of seismic wave with the oil/gas reservoirs. The method requires only the seismic data, with the characteristics of wide practicability and high success rate. The main gas-bearing series of strata in Su-10 block of Sulige gasfield are the Shanxi Formation Shanl and Shihezi Formation He8 Members of the Upper Paleozoic Permian System, with target layers of poor physical properties, belonging to typical tight sandstone gas reservoirs. Taking the Su-10 block for example, the appli- cation of resonance method petroleum detection technology to tight sandstone gas reservoirs is described in the paper. The results show that the resonance method hydrocarbon detection technology is suitable for tight sandstone gas reservoirs. The distribution maps of gas reservoirs derived from the technology provide a reliable geological basis for the next step well deployment of the study area.
