Cementing Technology for Ultra Deep Horizontal Wells in Block Donghe,Tarim.

The geology model is established on the basis of integrated analysis to static and dynamic data of water flooding well groups in the Tarim Donghe oil field .

Research on gas controlling by tectonism of center and the south of Hedong coalfield;

This paper deals with the coal-bearing measures of the Taiyuan Formation (C2) in the Fugu - Baode mine of the Hedong coalfield (the Northwest China) on the basis of the sedimentary characteristics of a main sandstone body (the Qiaotou sandstone body), including its mineralogy, petrology, textures, sedimentary structures, paleocurrents and spatial geometry.

The authors discover, in the Carboniferous-Permian coal reservoir in Hedong coalfield, Shanxi Province, two groups of joints similar to the traditional exo_joints in scale and to the cleat in occurrence, joint feature, growth carrier and other features.
