| 摘 要： | 对于已进入开发中后期的碳酸盐岩缝洞型油气藏,进行缝洞单元精细研究非常重要。盲目部署加密井,很容易导致因为所在单元的储量已被动用而失利。本文采用的碳酸盐岩缝洞单元多学科综合划分方法是:在有井控制的地区,首先分析井间连通性,然后结合生产动态、常规解析试井、流体性质、数值试井等多学科资料确定缝洞单元边界;在无井控制的地区,影响连通性最重要的主控因素是储层本身的相互连通性,其次才是断裂和裂缝,这时可在连通性约束下进行储层和裂缝预测,并以此为主要依据确定缝洞单元边界。对塔里木盆地轮古油气田轮古11井区划分出80个缝洞单元,其中有55个为储量未动用单元(潜力单元),并部署了一些加密井,已钻的XW1井获得了成功,投产初期日产油95t,不含水。

| Abstract: | It is important for the fractured and caved carbonate oil and gas reservoirs during the middle-late development period to study fracture-cave units in detail.Such blind deployment as infilling wells will be likely to lead to defeat because of having used the petroleum reserves in fracture-cave units.A method of multi-subject integrated division of fracture-cave units is proposed to determine the boundaries of fracture-cave units for the carbonate reservoirs in well areas and no well areas.This method is applied in Well LG 11 area of Lungu Oil Field where 80 fracture-cave units are divided,among which 55 units are reserves-unused(potential units).Some infill wells are deployed in this area,in which the drilled Well WX-1 is succeeded and yields 95t of oil per day,without water. |
