分注合采宋芳屯油田州16块葡、扶油层工艺技术

Individual injection and combined picking technology used in Zhou 16Pu-Fu reservoir of Songfangtun oil field

论述了宋芳屯油田葡萄花、扶余油层的地质特点 ,分析了对两套油层的合采状况 .结果表明 :在上部层段低流压时 ,对不同埋深、不同性质的两套油层合采是合适的 ,分注也是适宜的 .合采后 ,芳 2 48-12 6井葡萄花油层产量保持程度为当初的 6 9.4% ,扶余油层为当初的 2 2 .9% ,与单采相近 .仅 2个月时间 ,扶余油田产量提高了 8.5 5 % 。

This paper discusses the geological feature and mining state of the Putaohua-Fuyu oil layer.The result from the analysis and search of the combined mining two layers indicats that it was adaptive to do incorporate mining of two layers which were different in deepth and character and that it was feasible to inject separately.The output of well Fang 248-126 in the Putaohua oil layer retained 69.4% of it's original production,and Fuyu oil layer retained 22.9%. These were close to what were mined individually.Only in two months the output of Fuyu oil field had increased by 8.55%. So the effect of separate injecting was very obvious.
