CARACOLES油田气举生产管柱和换阀换层投捞技术

The Wireline Running and Pulling Technique of Exchanging Gas Lift Valves and Reservoir Layers for Gas Lift Producing Tubing String in Caracoles Oilfield

委内瑞拉CARACOLES油田采用适合于油藏特点的半闭式连续气举生产管柱,应用细钢丝投捞技术,不动油井管柱即可实现更换气举阀和换层生产。不仅降低了成本,而且可避免因作业而影响油井的生产时率,争取了生产主动权;同时,便于油井的气举优化,使油井处于较佳的生产状态。

Venezuela Caracoles oilfield adopts the semi-closed gas lift tubing string that is fit for reservoir characteristic, utilizes wireline operation technology to realize exchanging gas lift valves and exchanging layers producing without pulling tubing string. The result is not only to decrease cost, but also to avoid oil production rate to decrease because of conventional operation. We strive for initiative right of oil production. Contemporary, it is easy to optimize gas lift and enable oil wells to produce very good.
