高压物性取样技术在雅达油田的成功应用

Successful Application of PVT Technology in Yada Oilfield

伊朗雅达油田井况复杂(结蜡和出沥青严重),相对于常规作业施工难度大,顺利获取合格高压物性地层流体挑战性增加,引入高压物性取样技术,可为后期油田投产提供经济和技术支撑。高压物性取样标准化施工流程,以及在结蜡和出沥青严重的特殊井况下为顺利获取高压物性地层流体而做的工艺改良,提高了高压物性取样成功率,获取了具有代表性地层流样,为后期油田开发提供了理论依据。

Of Yada oilfield in Iran,well's condition is complex(( heavy wax and paraffin production),that has bigger operation difficult compared with the traditional operation and brings challenge to obtain the qualified PVT sample. By introducing PVT technology,economic and technical foundation for the future field production is provided. The standard PVT operation program,and improvement of obtaining the PVT sample in complicated well conditions are mainly introduced that increases the successful rate of qualified PVT sampling,gets the representative formation samples,which provides the theoretical basis for the future field development.
