Study On Precise Reservoir Description And Gas Enrichment Area Classify In The Sulige Gas Field

As a kind of clean, green, efficient energy,the position of natural gas in the world of energy is rising, in the late 1990 s, world demand for natural gas by 3 percent per year increase in inflation, predicted world gas demand in 2030 will reach 23%, instead of coal to become the second-largest primary energy.In recent years, with the gradual improvement of domestic natural gas industries, our natural industry has entered a rapid development period, since 2000, the domestic low permeability sandstone gas reservoirs in the rapid growth of reserves and production, especially in the growing proportion of output, 2020 is expected low permeability sandstone gas will account for 30% of annual oil and natural gas in total. At present, China was found in onshore natural gas reservoirs are mostly in low-permeability reservoirs and low permeability, ultra-low permeability reservoir accounts for a considerable proportion.Effective development of Sulige gas field as one of the country’s largest gas field, the West-East gas field shouldering responsibility, a matter of national economic construction and social stability are global relations strategy of sustainable economic and social development. Sulige gas field since 2001 submitted proven reserves of natural gas by the end of 2011, proved basic proven reserves of 3.17 trillion square, where proven reserves of 1.27 trillion square; annual natural gas output reached 13.72 billion square, accounting for China 18.2% oil, 13.6% of the national gas production. In order to meet domestic demand for natural gas, as soon as possible to complete the Sulige gas field, collaborating rolling exploration and development blocks the way to build a large-scale production, comprehensive geological study blocks, centralized screening reserves rich region build capacity. Over time, high quality reserves rich region gradually reduced in recent years, part of the regional gas wells drilled a single well productivity is low, and the water is serious, more difficult to block and stable, while increasing the gas production cost. The Sulige gas field subject to certain water area for the study, conducted on the basis of reserve-rich region Filter comprehensive geological study, to block well placement to provide evidence, at the same time as other similar-rich region provide gas reservoir screening reference and reference...
