摘要

南川区块平桥背斜五峰—龙马溪组含气页岩厚度大

目前采用一套层系开发

水平井井距500 m的条件下

存在着纵向动用程度低

平面动用不充分

未能实现页岩储量的充分动用。为了指导该地区页岩气的合理高效开发

提高储量动用程度和采收率

基于储层精细描述

重点刻画纵向上岩石微相及应力特征

明确其对压裂缝高和缝长的影响

利用微地震监测、气井生产数据历史拟合等技术方法

明确开发层系的划分和平面合理井距的优化。研究结果:（1）南川地区五峰—龙马溪组含气页岩划分为9个小层21个亚层

开发层系划分为上、下2套气层

其中下部气层为（1）—（5）小层

厚度35 m

上部气层为（6）—（9）小层

厚度76 m;（2）平桥背斜合理水平井间距在250 m。

Abstract

The gas-bearing shale in Wufeng-Longmaxi Formation of Pingqiao anticline in Nanchuan block is thick.Currently

the low vertical producing reserves

underused oil-bearing area remains in the development in the same layer series with the horizontal well spacing of 500 m

leading to the failure of fully exploitation of shale reserves.In order to guide reasonable and efficient development

and improve the reserve production degree and enhance recovery rate

based on the fine description of the reservoir

the description of the rock microfacies and stress characteristics in the vertical direction has been focused on

and the impact on the fracture height and fracture length has been clarified.By the microseismic monitoring

historical fitting of gas well production data and other technical methods

the division of the development layer series and the plane reasonable well spacing optimization have been determined.It is found that:firstly

the gas-bearing shale of Wufeng-Longmaxi Formation in Nanchuan area can be divided into nine small layers and 21 sub layers

and the development layer can be divided into two sets of gas layers.The lower①—⑤ layer are with the thickness of 35 m

while upper ⑥—⑨ layer are with the thickness of 76 m.Secondly

the reasonable horizontal well spacing of Pingqiao anticline is 250 m.
