Laboratory investigation of comprehensive treatment of alcohol-bearing waste water in Shanbei Gas Field;

Result The effective measures of improving gas production in Shanbei gas field are to reform gas formation, to reduc.

In order to solve the shortage of fracturing water in the Shanbei Oilfield, a study is initiated, it is intended to prepare water-based fracturing fluid using re-injected wastewater.

It is shown that there is closely relationship between formation of Shanbei gas area and Central Paleouplift.

The O1m_4￣5_1 in Shanganning Gas Field is a significant reserve gas pool with dolomite lithological character,low shale content, 4￣8 m thickness, 1%￣9% porosity without unified gas-water interface.
