China sits a top in gold production, consumption and import. The gold reserve of countries within “One Belt and One Road” amounts to 65% in the world, 39% in production, 51% in consumption according to the global gold reserve, production and consumption information. Those countries have potential in expanding production and markets. China’s most gold mines are small, low grade, and limited reserve, hard to meet gold demands in the future. It needs to import gold through overseas gold investment. Under “One Belt and One Road”, this paper analyzes their gold resource and production, market, investment environment among the countries within “One Belt and One Road”, and presents three priority overseas areas for gold investment, 1） Russia and Mongolia; 2） middle and western Asia, Kazakhstan, Uzbekistan, Kyrghyzstan, Tajikistan, Pakistan, and Iran; 3) South Africa, Ethiopia, Kenya, Tanzania and Congo. Investment strategy is also given for each area.

This paper, based on the drilling, logging, and thin sections of cores, studies the features and production of Sha-3 Member Reservoir of Western depression in Liaohe basin. The Sha-3 Member reservoir is chiefly turbidite, which can be classified into three sub-members, Lianhua oil-bearing bed, Dalinghe oil-bearing bed and Rehetai oil-bearing bed according to their lithology and sedimentation. The later both are the major reservoirs which are sandstone in lithology with clastic grains and low maturity, implying a near source and quick sediment. The petropysical features of reservoir, closely related to facies zone, are largely influenced by sedimentary zones, the maturity of clastic components, post-diagenesis, cementation and corrosion, etc.

This paper, based on 100 counties in Liaoning province, selects some key indexes which can reflect the comprehensive development level of regional economy to classify, by means of the major constitute analysis and clustering analysis, the regions into three types, developed, moderate and underdeveloped. A present social-economic development status is stated in three types of regions. The authors also present approaches to the unbalanced development in different regions.
