桥式偏心分注工艺技术研究及推广应用

Bridge-eccentric separate injection technology research and popularization application

针对目前在用的常规偏心分注工艺技术在分层流量测试上存在较大误差,各层之间进行流量和压力测试时工作量大,调配效率较低,资料准确性不高的问题,引进了桥式偏心分注工艺。该工艺在吴仓堡、塞392、虎狼峁、五里湾等区块104口新增分注井得到大规模应用,简化了偏心分注井调配测试工艺,实现高效、准确分层流量和压力测试。

According to the currently used in conventional eccentric separate injection technology in stratified flow testing on larger error between each layer, flow rate and pressure testing workload, low efficiency of data distribution, the accuracy is not high, the introduction of bridge-eccentric separate injection technology. The technology in Wu Cang Pu, Sai 392, Hu Lang Mao, Wu Li Wan of 104 new injection well been largescale application, simplifies the eccentric separate injection well deployment testing technology, to achieve efficient, accurate stratification flow and pressure test.
