摘要
冀东南堡油田1-3人工岛国内第一个在浅海人工岛实施整体气举采油的平台。该岛是南堡油田1-5区的三个开发平台之一,地面上处于水深3～7 m的滩海区,将建成国内最大的气举采油平台。岛上气源充足,油井造斜点浅,井斜角大,井眼轨迹复杂,油井分布集中(井组内井距为4 m)。同时。该区气油比高、含水低,气举是最适合的举升方式。岛上气举管柱全部采用半闭式气举管柱,连续气举的采油方式。从已实施的44口井来看,人工岛实施气举采油可以有效降低运行成本且管理方便,效果显著。
The NP1-3 artificial island in Jidong Nanpu oilfield is the first platform which the Gas-lift recovery technology was applied in the epeiric sea artificial island inland.The NP1-3 artificial island which is in a water depth of 3 to 7 meters in shallow water area is one of the three production platform in NP 1-5 oilfield.We'll put it into the largest gas lift oil platform in China.Now there are enough natural gas to keep production.The deflection point is superficial part in oil wll,and deviation angle is very great,the complex well track.The well is concentrated distribution(well spacing is 4m for wells group),there are high GOR in this area.The gas lift lived with semi-closed gas lift pipe,continuous gas lift.We found that the Gas-lift recovery technology could decline running cost,administration was easy and the effect is visible.
