小洼油田洼38块东三Ⅰ段油藏开采技术研究与应用

Study and application of recovery technique for reservoirs in Dongsan I formation of block 38, Xiaowa oilfield

结合油藏开发特点和油井生产特点 ,运用油藏工程方法对洼 38块东三Ⅰ薄互层油藏进行研究 ,以改善其高轮次吞吐开发水平。通过绘制综合解释图版 ,从开发和工艺技术相结合的角度优化适合该类型油藏特点的开采技术。单注单采、复合防砂和优化射孔技术的综合应用使出砂严重的薄互层油藏取得了很好的生产效果 ,为实现薄互层有效开发 。

To improve development of multi cycle huff and puff, Dongsan I thin interbedded reservoirs in block Wa38 has been studied through reservoir engineering and combining features of reservoir development and well production. Recovery techniques suitable to this type of reservoirs are optimized through mapping of integrated interpretation chart. Good production effectiveness has been achieved in thin interbedded reservoirs with severe sand producing problem through injection and production in single well, composite sand control, and optimum perforation, thus providing a effective way for developing thin interbedded reservoirs and improving producing degree of residual reserves.
