Abstract

Настоящее изобретение относится к способу, где способ включает получение бурового раствора, содержащего водную текучую среду, поверхностно-активное вещество для получения микроэмульсии и, необязательно, неполярную текучую среду; и бурение скважины в подземной формации, содержащей маслянистую текучую среду или поровые каналы, или как то, так и другое, с использованием бурового раствора, где поверхностно-активное вещество для получения микроэмульсии образует микроэмульсию с маслянистой текучей средой в скважине или где поверхностно-активное вещество для получения микроэмульсии образует микроэмульсию, по меньшей мере, с неполярной текучей средой. Необязательно, способ включает получение бурового раствора, содержащего водную текучую среду основы и поверхностно-активное вещество для получения микроэмульсии; и бурение скважины в подземной формации, которая содержит поровые каналы; и предоставление возможности поверхностно-активному веществу удалять нефтяной блок, водяной блок или как то, так и другое из поровых каналов. В соответствии со способом подземная формация может иметь восстанавливаемую продуктивность более чем примерно 50%.
