摘要
针对沈 84 -安 12块及曙光古潜山油藏高含水开发中后期形成的大孔道及裂缝 ,研究了粉煤灰及橡胶粉填充的聚丙烯酰胺—三聚氰胺冻胶堵剂及不饱和聚酯树脂堵剂封堵大孔道技术。该技术现场应用 10井次 ,取得了明显增油降水效果 ,对提高油藏水驱波及程度 。
Aiming at the large holes and cracks formed in the middle and late recovery stage of Shen 84 -AN 12 block and Shuguang Guqianshan reservoir with the high water cut, the article researched the filling large holes technology filled by polypropylene/melamine jelly plugging agent and under-saturated polyester resin plugging agent mixed with the tiny coal ash and latex powder. Through 10 technical appliances, this technology gets significant effects to enhance oil production and decline water cut. Increasing the water-drive reservoir speeding degree, it brought important purpose to improve the development impacts.
