二氧化碳增能解堵技术在延长油田的应用
Reservoir Blockage Removal/ Pressure Boosting in
介绍了二氧化碳增能解堵原理，在延长油田油井的施工方法和程序以及所用工作液的组成。该技术作为油井增产措施应用于延长油田下寺湾采油厂26口井作业后采油时间为4个月的基础上实现平均单年增油41.49吨，当年可完全收回投资成本，实现投入与产出比为1：3。
he principles of reservoir blockage removal/ pressure boosting by CO2 (BR/CO2 PB), the composition and the performance properties of the working fluids and the application of this combinational technology for oil well stimulation in low permeable and low porosity reservoirs in Xiasiwan, North Shaanxi, are presented. This program was applied in 26 wells, and significant achievements was got: increment in crude oil production per well 41.49 tones in average, and the ratio of input-output got to 1: 3.
