Ultimate potential resource prediction and exploration target in East Depression, Baise Basin
-
摘要: 百色盆地东部坳陷石油资源探明程度37.59%。应用油藏规模序列法,对其终极资源量进行预测,结果显示仍有待发现油藏35个,待发现油藏地质储量2836×104t。其中,储量规模大于100×104t的待发现油藏有11个,待发现资源量1 622×104t;储量规模小于100×104t的待发现油藏有24个,待发现资源量1 214×104t。预测油藏预测储量与实际储量相对误差小于10%。待发现资源量主要分布在中央凹陷带隐蔽油气藏、南部斜坡带三角洲砂体和滩坝砂、前第三系潜山、陡坡带砂砾岩扇体和红层、那读组页岩气重点领域。Abstract: The confirmed recoverable oil resource was estimated to be 37.59% in the East Depression of the Baise Basin. By means of reservoir scale sequence, the ultimate potential resource of the depression was predicted, indicating 35 reservoirs and 2 836×104 t reserves remained to be discovered. 11 undiscovered reservoirs (total reserves 1 622×104 t) had the reserves of more than 100×104 t. 24 undiscovered reservoirs (total reserves 1 214×104 t) had the reserves of less than 100×104 t. The difference between predicted and actual oil reserves was less than 10%. The resources remained to be discovered mainly located in covered oil reservoirs in the Central Sag, delta sandbodies and beach-bar sandbodies in the Southern Slope, pre-Tertiary buried hill, glutenite and red bed in the steep slope and shale in the Nadu Formation.
