摘要
海26块为复杂断块油藏,采用注水方式开发。由于地质条件复杂,油藏长期处于低速开采状况。近几年来,在油藏精细描述的基础上,因地制宜采取点状注水、不规则面积注水等方式不断完善注采井网,利用三管分层注水、周期注水等注水方式不断提高水驱波及体积,利用层间接替、侧钻、堵水、防砂等配套技术手段不断提高储量动用程度,有效地改善了复杂断块开发水平。
Hai-26 block is a complex fault block oil reservoir developed by water injection. Due to the complex geological conditions, the reservoir is in low speed state of exploration. In recent years, on the basis of meticulous reservoir description, the methods of point injection and irregular area of water injection were applied to improve injection-production well network. Using three separate layer water injection and cyclic water injection mode continuously improved water flooding swept volume. In order to increase reserves and effectively improve the level of development of the complex fault block, the following means were employed, such as interlayer succeeding, sidetracking, water plugging, and sand prevention.
