实施各项辅助措施,提高老区常规吞吐效果

Analysis of auxiliary measures implemented to improve conventional stimulation effect in old oilfields

欢127东块自1989年投入开发,目前处于开发中后期,受水淹、汽窜、出砂、井况差等因素的影响,区块常规蒸汽吞吐效果逐年变差,油汽比逐年降低,针对该区块存在的各种问题,不断探索新的解决方案和途径,实施了三种辅助常规吞吐措施,提高了老区常规吞吐效果,最大限度地改善了油藏开发效果。

Huan 127 east block reservoir is currently in the late development stage since its investment development in 1989.Owing to the effects of water flooding,steam channeling,sanding,bad well condition and other factors,the effect of conventionalsteam stimulation in this block goes from bad to worse and the oil-steam ratio is decreasing year by year. To solve all kinds ofproblems existed in this block,new solutions and ways are constantly researched and three conventional auxiliary stimulation measuresare implemented,and finally the effect of conventional stimulation is improved,and also the effect of reservoir development ismaximized in this old block.
