摘要:
井下產氣和脫氣會使產液量和含水率測量誤差增大,嚴重影響兩相流儀器的產液剖面測井質量。以阻抗式產液剖面測井儀為基礎研制氣體分流型產液剖面測井儀,設計井下氣液分流器,在小氣量條件下將氣體實時分流,使氣體不流經測量通道,消除氣體對產液量和含水率測量的影響。在多相流模擬實驗室進行油/氣/水三相流的動態模擬實驗。實驗結果表明:氣體流量在5 m3/d以下時,流量測量誤差不大于5%,與油/水兩相流條件下的測量誤差相當;含水率測量誤差不大于6%,與未進行氣體分流的測量結果相比顯著提高。氣體分流型儀器與兩相流測井儀相比可以顯著提高測量精度,與三相流測井儀相比標定工作量小、資料解釋簡單。氣體分流型產液剖面測井儀具有結構簡單,成本低的優點,可以提高低產氣油井的產出剖面測井資料質量。
Abstract:
Downhole gas production and degassing will increase the measurement errors of liquid production and water-cut, and seriously affect the production profile logging quality of the two-phase flow instruments. Based on the impedance production profile logging tool, a gas-split production profile logging tool is developed, and a downhole gas-liquid splitter is designed. Given a low gas flow rate, the gas can be diverted in real time, so that the gas does not flow through the measurement channel, thus eliminating the influence of gas on the measurement of liquid production and water-cut. The dynamic simulation experiment of oil-gas-water three-phase flow was carried out in the multiphase flow simulation laboratory. According to the experimental results, when the gas flow rate is less than 5 m3/d, the error of flow measurement is less than 5%, which is equivalent to that of the oil-water two-phase flow; the error of water-cut measurement is less than 6%, reflecting a significantly improved accuracy than the measurement without gas splitting. The gas-split production profile logging tool achieves a much higher accuracy than the two-phase flow logging tool, and needs less calibration workload and simpler data interpretation than the three-phase flow logging tool. Furthermore, the gas-split production profile logging tool is applicable and practical for its simple structure and low cost. It can significantly improve the quality of production profile logging for low-yield wells.
