川西南筇竹寺组页岩气复合地质导向方法研究
|
摘要
目前针对川西南寒武系筇竹寺组页岩气的勘探已取得可喜的油气成果,揭示了筇竹寺组页岩气藏具有良好的勘探开发前景。文章总结富气页岩储层地质的测井响应特征,利用岩心刻度、元素录井、岩屑伽马能谱录井、随钻测量等方法建立了岩石组分含量、孔隙度、有机碳含量和含气量、脆性随钻评价模型,形成了一套适用于筇竹寺组页岩气储层的复合地质导向方法,并在川西南地区筇竹寺组页岩气勘探中取得了良好的应用效果。
At present,good oil and gas results have been obtained during the shale gas exploration at Cambrian Qiongzhusi Formation in the southwestern Sichuan Basin,showing that the shale gas reservoir,Qiongzhusi Formation,has good prospects for exploration and development. On the basis of summarizing the logging response characteristics of "four highs and three lows"wells in rich gas shale reservoirs,the models including rock component contents,porosity,total organic carbon content,gas content and brittleness evaluation while drilling are established by using coring,element logging,cuttings gamma-ray logging and drilling measurement. A set of compound geosteering method for drilling through shale gas reservoirs in Qiongzhusi group is formed,and good application effects already obtained there.
