摘    要:卧龙河气田石炭系气藏经历10多年的开采,发现气井的生产与早期的地质认识不相吻合,位于构造轴部的少数几口气井已逐渐构成主力生产井,并比预测的稳产期更长,稳产气量更多。为了重新认识该气田的地质模式。本次利用三维地震资料和实钻井资料对卧龙河构造进行重新解释,发现阳底构造为断膝状背斜,而非原二维地震解释的“半边”形断背斜,构造轴部与主断层间为陡褶状。该构造陡带的石炭系地质储量大,丰度高,渗透性好,对轴部生产井起到能量补给作用,使其产能大,稳产时间长,控制的动态储量数倍于容积法地质储量。经数模拟合。该地质模式与实际生产过程吻合较好,并为解决川东地区其它类似的特殊气藏提供了新的技术思路。

关 键 词:卧龙河气田  石炭系气藏  构造陡带  含气性评价  地震勘探  地质

Abstract:??Carboniferous gas reservoir in Wolonghe field has been exploited for more than ten years.It was found that the production results weren't coincident with the former geological knowledge,i.e.that a few gas wells distributed along structural axis have gradually turned into the major producing wells and their stable production period and output are longer and larger than those predicted before.In order to reconsider the geological mode of the gas field,the reinterpretation of Wolonghe structure was carried out by applying 3-D seismic and drilling data and it was found that the structural map (bottom of Yangxin Formation,Lower Permian) shows up a fault-knee anticline rather than the "half" faulted anticline interpreted by applying 2 D seismic data originally;and a steep fold is found between axial culmination and main fault.The Carboniferous reservoir in the steep zone of the structure has a great deal of gas reserves in place,large abundance and high permeability,which plays an important role in supplying energy to the producing wells distributed along axis,thus causing them to produce gas with high output for a long time and the dynamic reserves controlled by them to be several times as much as the volumetric method reserves in place.Through simulating it is shown that this geological mode is well tallied with actual producing process,thus providing a new technical method for studying the other special gas reservoirs in East Sichuan.
Keywords:Wolonghe gas field  Carboniferous period  Gas reservoir  Steep zone  Reserve  Energy supply
