在油藏开发后期,会形成一些体积很小的油环。单独对每个油环建造生产井是不经济的。连通器/导管(CC)井技术为这些油环的开发提供了一条途径。导管井(供给井)是穿过油藏边缘的水平井眼,在油藏中作为水平流动的管道;连通器井(生产井)连通导管井并完成从地下到地面的生产。本文以Darat CC井项目的成功为例,介绍了连通器/导管井技术的实现,证明这项技术是可行的。
In the later stage of reservoir development, some small oil rings will be formed. It is not economical to build a production well for each oil ring separately. Communicator / Conduit (CC) well technology provides a way for the development of these oil rings. The aqueduct (feedwell) is a horizontal wellbore that runs through the edge of the reservoir and acts as a horizontal flow conduit in the reservoir; the communicator well (production well) communicates with the conduit well and completes production from ground to ground. Taking the success of the Darat CC Well project as an example, this paper introduces the implementation of the Communicator / Conduit Wells technology to prove that this technique is feasible.
