Abstract

Abstract:

Chemical compositions and carbon isotopes of 34 natural gas samples, collected from 13 oil and gas fields in western depression of Qaidam basin, are measured and analyzed. Based on the carbon isotopes of methane, ethane and propane in the gas samples, the natural gas in western depression of Qaidam basin can be divided into 4 different types, including sapropel type oil associated gas, mixed type oil associated gas, coal related (humic) gas and hybrid gas. Most of the gases in western depression are cogenetic and synchronous sapropel type oil associated gas, mixed type oil associated gas and coal related gas. Hybrid gas, consisted of biogas, immature mixed type oil associated gas and low mature mixed type oil associated gas, distribute only in the shallow layers (Neogene) in Gas Hure oilfield in Gas faulted depression, the Yuejin No. 2 west intersection point, Youshashan oilfield and Wunan oilfield in Kunbei fault bench zone.

Key words: natural gas, mixed gas, carbon isotope, Qaidam basin
