摘要
蠡县斜坡是华北油田勘探的重点区带,该区块由于碳酸盐胶结、孔隙结构复杂、地层水矿化度变化大等原因,存在低阻油层及低孔低渗储层并存现象。在系统分析试验SB-3资料的基础上,研究分析并确定了该区块影响储层的主控因素,针对其具体特点,进行了储层评价方法的研究,确定了适合该区块特征的解释方法及解释模型。通过资料处理验证了此研究方法的可行性及实用性。
Lixian Slope was a key block of oil exploration in Huabei Oilfield,because of carbonate cementation,complex pore structure,high changes of water salinity in the block,there existed coexistence of low resistance oil reservoirs and low porosity and low permeability reservoirs.Based on systematic analysis of experimental data,the main control factors of reservoir influence were studied,analyzed and determined.Aiming at the specific characteristics,the method of reservoir evaluation was studied,the interpretation method and model suitable for this block are determined.Through the data processing,the feasibility and usability of the method is verified.
