"Multi-factor controlling,four-factor entrapping and key-factor enrichment" of stratigraphic-lithologic reservoirs and exploration practice in Erlian Basin (Ⅳ)——Exploration practice;

Domestic hydrocarbon resources exploration priority and orientation during the eleventh five-year plan;

Technology of natural gas exploration and evaluation based on well-logging data;

The Important Technology of Continuous Prospecting and Exploitation at the Complicated Section of Fault;

The state-owned petroleum enterprises are the main part of prospecting and exploitation of petroleum resources in China.

Five potential mineral sites for further prospecting are predicted, thus providing a prospecting basis for full use of the resources of iron and copper ores in this area.

Discussion on collapsible loess survey and treatment methods of subgrade;

The equipment was further modified being directed against the existing problems in application so that made it better suit the survey under the adverse conditions of waters, tidal-flat area, marsh, hard land, anoxia plateau and so on.

According to the landslide of soft soil foundat ion in one sector of Weining Station based upon geological survey its causing re asons are analyzed.

Therefore,they are more difficult in geological investigation,design,construction and operation than land tunnels.

The article combine with the project example to introduces the investigation method of karstic water source place.

The techniques of the crooked line seismic reflection engineering geology investigation which include crooked line design,data acquisition, data processing,data explaining,and so on and two examples are introduced in this paper based on the Principle of commondepth cell stacking.
