百色油田泡沫驱油效果初步分析

A PRELIMINARY ANALYSIS OF THE FIELD RESULTSOF FOAM FLOOD IN BAISE OIL FLELDS

本文介绍了驱油用泡沫的配方筛选，用筛选出的经济配方（０．３％ＡＢＳ＋０．００５％ＰＨＰ）起泡液在仑１６块东区岩性断块砂岩油藏进行了氮气泡沫驱油试验，用优化配方（１％ＡＢＳ＋０．１％ＬＶＣＭＣ＋０．００５％ＰＨＰ＋０．５％ＮａＣｌ）起泡液在百４块西区裂缝孔隙和裂缝溶洞型灰岩油藏进行了空气泡沫驱油试验，均获得了良好的增产和经济效果。

wo formulations of foaming solution were chosen for performing foam flood at Baise Oil fields through a series of ingredientsieving experiments. Of them the economic one (0.3% ABS+0.005% PHP) was used for nitrogen foam flooding of a faultblock sandstone reservoir at east area of Block Lun18 and the optimal one (1% ABS+0.1% LVCMC+0.005% PHP+0.5% NaCl)--for air foam flooding of a fractured limestone reservoir at west area of Block Bai4. In the two pilots satisfactory results were obtained in productivity enhancement at acceptable costs.
