A DEMANDING DEVELOPMENT TO HYDROCARBON RESOURCES IN CHUXIONG BASIN

Mesozoic and Paleozoic marine hydrocarbon resources have been developed in South China except Sichuan Basin for half a century. The Chuxiong Basin is very important in oil and gas exploration in South China because of its material basis and favorable tectonic environment forming large-and-middle scale of hydrocarbon accumulation. Hydrocarbon source rocks mainly developed in €₁, O_1-2, D_1-2, T₃y, T₃l, T₃g, T₃s and J_1-2. Two important plays are Middle-Upper Devonian to the lower part of Upper Triassic marine formation and the upper part of Triassic land formation to Lower-Middle Jurassic. Exploration should be implemented along the margin of platform because of a bad hydrocarbon generation condition and other disadvantages as complicated structural deformation, intensive uplifting and high level of evolution inside the platform.
