1问题的提出科尔沁油田油藏地质条件复杂，是典型的外围中生代复杂断块，由于其储层均为快速沉积产物，后期成岩作用比较强烈，砂体平面分布较小，变异严重，纵向上排均质性强，因此油田转入注水开发后，水驱效果不理想，具体表现为：1．1平面矛盾突出，水淹、水窜严重科尔沁油
1 PROBLEM PROBLEMS The geological conditions of the Horqin oilfield are complex and are typical peripheral Mesozoic complex fault blocks. Due to the rapid sedimentary facies of the reservoirs and the strong diagenesis in the later stage, the distribution of the sand bodies is rather small with serious variation. The upper vertical row Homogeneity, so the oil field into the water after the development of water flooding is not ideal, the specific performance: 1.1 plane contradiction prominent, flooded, water channeling serious Kerqqin oil
