苏里格气田东区多层系气藏储层物性下限及控制因素
LOWER LIMITS OF THE PHYSICAL PROPERTIES AND THEIR CONTROLLING FACTORS FOR MULTIPLE SERIES OF GAS RESERVOIRS IN EAST BLOCK OF SULIGE GASFIELD
摘要
Abstract
The tight sandstone reservoirs in Member He8, Shanl and Shan2 of Changqing Oilfield are characterized by the typical low-porosity and low-permeability multiple series of the strata. The aspects of the lithology, physical properties, pore structures, pore micro-features and so on are analyzed. Through the contrast of the micro-characteristics in the pores of both gas reservoirs and dry layer and moreover on the basis of the systematical studies on the micro-features of the reservoirs, the relation between the permeabilities and productivity is researched by production data method. And furthermore the above method is tested by productivity simulating approach, finally the lower limits of the porosity and permeability for the effective reservoirs are determined. The factors of the pore structural type, capillary pressure curve characteristics, digenetic features and so forth result in the gas-bearing differences of the reservoirs.关键词
