摘要
针对涪陵页岩气田地质构造复杂,页岩气水平井井眼轨迹控制要求较高,水平段稳定在优质储层中穿行难度较大的问题。提出了对不同地层变化类型采用不同导向手段的方法,给出了控制井眼轨迹变化的经验公式。通过该地质导向方法在涪陵页岩气田水平井现场应用,页岩气水平井水平段在优质储层中的穿行率达到80%以上,表明运用该地质导向方法可以保证水平段基本稳定在优质储层中穿行。
In order to solve the problem that the complex geological structure of filling shale gas field cause shale gas horizontal well track control the demand is higher and horizontal part of the horizontal well stability through difficult in the high-quality reservoirs. Put forward on different kinds of formation change with different geosteering method, also provide an empirical formula of control horizontal well track changes. Through the geosteering method in fuling shale gas field application of horizontal well, shale gas horizontal part of the horizontal well in the high quality reservoirs through rate of more than 80%, shows that using the geosteering method can guarantee the stability of horizontal part basic on the high quality reservoirs.
