一辽河盆地火成岩储层评价标准与有效储层物性下限
Evaluation criterion and cut-off value of igneous rock reservoirs in Liaohe Basin
摘要
Abstract
Based on previous results of the reservoir porosity-permeability, oil-bearing occurrence and oil testing of 40 repre-sentative wells in eastern depression Liaohe Basin, the cut-off value of the reservoir physical properties and reasonable evalu-ation criteria of study area were evaluated using a series of approaches, including empirical coefficient method, irreducible water saturation method, oil occurrence method and formation testing method. The results show that when the porosity is less than 3%, or the permeability is less than 0. 03×10-3 μm2, the reservoir usually is dry and does not contain any oil or gas. Therefore 3% porosity and 0. 03×10-3μm2 permeability are chosen as the cut-off values for effective reservoirs of the igneous rocks. Based on porosity, permeability, oil-bearing occurrence and oil testing results, the igneous rock reservoirs can be characterized into four classes:( I) high porosity and high permeability, (Ⅱ) high-medium porosity and permeability, (Ⅲ) medium porosity and permeability and ( IV) low porosity and permeability. The evaluation criteria and the cut-off values ob-jectively describe the characteristics of igneous rock reservoir and can be applied preferably in decision-making for oil and gas exploration.关键词
