上古生界致密砂岩气藏包含多套气层，最具有经济价值的高产层为下石盒子组盒2段，但水平井产气量差异较大。利用钻井、录井、试气和储层预测资料，对沉积、物性、电性、含气性及地震属性等特征深入分析研究，认为高产储层分布于辫状河的高能河道，粒度较粗，泥质含量低，物性较好，储集空间发育，具有“两高三低”的电性特征，录井显示含气性效果较好，地震反射强度属性为短轴强反射特征，其中物性为高产主要控制因素。利用“五有利”的方法，优选出有利开发区，进行井位部署，提高了钻井的高产率。

The compact sandstone gas reservoirs of upper paleozoic contains several sets of gas sands,the member 2 of Xiashihezi Formation is the most economical value reservoir. Gas production of horizontal wells are quite differ-ent. Drilling,logging,gas testing and reservoir forecasts are used to study the characteristic of sedimentary,physical property,electric,gas-bearing properties and seismic attributes. Reservoir of high yield located at the energy chan-nel of braided river,which have coarse grain size,low shale content,good physical and reservoir space. The electri-cal characteristic is three high and two low,gas testing is favorable,the characteristic of seismic reflection intensity is short axis and strong reflection. The physical property is the main controlling factor. Using of five elements to se-lect the favorable area and well placement,improve the success rate of drilling.
