Geological characteristics and main challenges of onshore deep oil and gas development in China

More than 30 years of continuous development has made onshore deep and ultra-deep conventional unconventional oil gas become an integral part increasing the energy reserves output by China’s petroleum industry. Based on geological conditions in country, present study finds that paleo stratum burial are two basic characteristics gas. Furthermore, we put forward notion it is necessary to strengthen fundamental research theories four aspects core technology five It suggested special importance promote scientific technological through exploration “myriameter deep” wells as starting point, so boost field China.
