由于受地质年代的影响,我国大多油田含油层形成了各式各样的沉积层,很多的储集层都具有多层的特性,因此,各层的含油层其物理特性也各不相同,可见一斑,油田已进入特高含水、特高采出程度的双特高开发阶段。如何把地下难以开采的油开采出来,成为亟待解决的问题。据此,文章在二次评价、分层开发、立体开发、多元开发等理念部署产能建设大盘。按照多元开发方式,科研人员在多层油藏扩边滚动部署,采用直井、水平井两种井型,实施多元开发。同时,利用分层开发方式与深部调驱、直平组合式注水紧密结合,在曙22等复杂断块边缘完善注采井网,为实现区块高效开发夯实基础。
Due to the influence of geological age, most oil-bearing formations in our country have a variety of sedimentary layers. Many reservoirs have the characteristics of multi-layers. Therefore, the physical properties of oil-bearing layers in each layer are also different As a result, the oil field has entered the stage of dual-high development of ultra-high water-cut and extra-high-level production. How to mine hard-to-get underground oil has become a problem to be solved urgently. Accordingly, the article in the second evaluation, stratified development, three-dimensional development, such as the concept of diversified development capacity to build the broader market. In accordance with the multi-development approach, researchers deploying multi-layered reservoirs rolling expansion, the use of vertical well, horizontal well two well-type, the implementation of diversified development. At the same time, using the method of stratified development and deep flooding, direct combination of water injection combined closely to improve the edge of the block 22 and other complex wellbore injection and production well pattern, in order to achieve a solid foundation for efficient development of the block.
