Study of Structure and Pool-forming Condition of Dongying Formation in the Central Uplift of Dongying Sag;

Fault systems in the Central uplift of the Dongying depression are complex.

Quantitative study of the influence of structural adjustments on the accumulation and distribution of petroleum in central uplift belt,Tarim basin;

Potential areas and exploration direction in the central uplift belt of the Tarim Basin;

An analysis of oil-source characteristics of central uplift belt in Dongying depression;

The Process of Structure-sedimentary and Their Correlation of the Cambrian Peroid in the Central Uplift Belt, Tarim Basin;

Structural features of the central uplift belt have been investigated by basin analysis and accommodation zone theory,indicating that,uplift forming has been controlled by the second grade faults,local structure has been controlled and complicated by the third and forth grade faults,and oil-gas accumulation level has been controlled by the combination features of faults.

Focusing the main research goal on paleo-central uplift belt of northern Songliao basin,guided by the train of research thought of integrating geology and geophysics, and usingmultiple means and methods, this paper reveals the structural characters and the evolutionaryprocess of paleo-central uplift belt in different aspects, and also disclose the distribution statusof basement lithologies.
