Research and Application of Synchronous Dynamic Test and Adjustment Technology for Novel Water Injection Well
To solve the problem that the conventional layered water injection technology has too long test and adjustment period and strong interference among layers at the ultra-high water cut stage, a novel digital synchronous dynamic test and adjustment technology is proposed and developed in this paper. Many advanced technologies, including digital multi-information test and adjustment, bidirectional transmission of remote wireless signals and non-contact electric energy transformation, are adopted to combine multi-information test and flow control to be a whole thrown into the well. This technology can automatically monitor each water injection layer and adjust water flow in user-defined period without any intervention; it can synchronously and dynamically adjust flow of each layer; and it also can monitor and adjust flow data by the redisplay of computer. The experimental results show that this technology not only reduces the field workload and improves water injection effect, but also provides the basis of data analysis for implementation and adjustment of meticulous oil development plan.
