井间约束的储层建模方法——以DND岩性气藏为例

Research on Cross-well Constrained Reservoir Modeling:Taking DND Reservoir for Example

针对岩性气藏建模,充分利用地震资料和沉积相研究成果,通过地震相和沉积相两次控制和约束,削弱随机建模方法上的局限,减小井间模拟的多解性。此研究的特点是:应用地震资料和沉积相作为约束,并以它作为趋势控制岩性展布。经过新井验证,建立的储层模型精度较高。

For the lithological gas reservoir modeling,this paper uses earthquake data and the research result of the depositional facie as well as the result of the twice controlling and restraining for seismic facie and precipitation facie to reduce the limitation of stochastic modeling and ambiguity for cross-well modeling.Different from others,this method take seismic data and depositional facie as restrains,and utilizes that as the trend to control lithology thoroughgoing.The new wells test result show the precision of reservoir model that developed by this paper is satisfactory.
