井下节流工艺在苏中区块的运用

APPLICATION OF DOWNHOLE THROTTLING TECHNOLOGY TO CENTRAL SULIGE BLOCK

针对气井在一定条件下形成的水合物堵塞井筒、管线、严重影响到气井正常生产的问题,对井下节流工艺进行了分析研究,并结合井下节流工艺在苏中区块的应用,验证了井下节流工艺对水合物预防的有效性,为天然气水合物的防治提供了必要的依据,而且大幅度降低了苏中区块地面建设的投资与生产成本,从而获得良好的经济效益。

Formed under a certain condition and in gas wells,gas hydrate can plug wellbore and pipeline,seriously resulting in a normal production.So,in this study,downhole throttling technology is analyzed,and after its application to central Sulige block,it is indicated that this technology is available for preventing gas hydrate.Also,it provides a necessary basis for controlling gas hydrate.Moreover,the downhole throttling technology may reduce greatly the production and investment cost of surface construction in this block.Thus,the better economic benefits can be obtained.
