二连盆地最早开始油气勘探的巴音都兰凹陷虽然生油条件好 ,但大型构造圈闭与有利储集相带不匹配 ,所以 2 0余年勘探构造油藏一直未能取得突破。 2 0 0 1年转变思路 ,注重隐蔽油气藏的勘探 ,以LANDMARK地震解释系统为依托 ,运用STRATA、ISIS、JASON等地震反演软件建立构造 岩性油藏模式 ,精细识别巴Ⅱ构造的下白垩统巴彦花群岩性体 ,部署的 5口探井钻探全部获得商业油流 ,发现了具有千万吨级探明储量规模的宝力格油田 ,为二连探区新建产能 7.68× 10 4t。图 3(常亮摘 )
Although the oil generation conditions are good in the Bayin Dulan Sag, which was the earliest oil and gas exploration in Erlian Basin, the large structural traps did not match the favorable reservoir facies belt, so breakthrough in exploration of structural reservoirs has not been achieved for more than 20 years. In 2001, we changed our thinking and focused on the exploration of subtle reservoirs. Based on the LANDMARK seismic interpretation system, we established the lithologic reservoir model using seismic inversion software such as STRATA, ISIS and JASON, and finely identified the lower Cretaceous The system of lithology of the Tongyashanhua group and the deployment of 5 exploration wells all obtained commercial oil flow. The Baolige oilfield with a proven reserves of 10 million tons was discovered, with a new production capacity of 7.68 × 10 4 t for the Erlian exploration area. Figure 3 (often bright pick)
