摘要:
井筒溫度和壓力是儲氣庫注采井生產運行中的重要參數,準確預測井筒溫度和壓力分布是優化注采方案和進行注采井完整性評價的基礎和關鍵。目前注采井井下溫度和壓力監測主要采用繩索或連續油管下入監測儀器的方式,然而對于具有大斜度、水平井、完井管柱結構復雜、注采氣量大等特點的相國寺儲氣庫注采井存在作業風險大、費用高等問題。為此,利用PIPESIM軟件建立了管柱流動模型,基于預測值和連續油管實測值,優選了摩阻系數和傳熱系數,并對相國寺儲氣庫氣井進行了平衡期、注氣和采氣階段井筒溫度和壓力分布預測。結果表明:溫度預測值與實測值的相對誤差小于5%,壓力預測值與實測值的相對誤差小于2%,預測精度可接受,可滿足注采井溫度壓力預測的需求,并可適當減少下連續油管測試次數以及作業帶來的風險,可為儲氣庫井注采方案優化和井筒壓力評價提供依據。
Abstract:
Wellbore temperature and pressure are important parameters in the production and operation of gas injection and production wells. Accurate prediction of wellbore temperature and pressure distribution is the basis to optimize the injectionproduction plan and the integrity evaluation of injectionproduction wells. At present, the temperature and pressure monitoring of injection and production wells mainly rely on the way of ropes or coiled tubing. However, for the largeslope wells, horizontal wells, complex string structure, large gas injection and production,.Problems such as high operation risk and high cost.So, PIPESIM software is used to establish the physical flow model. Based on the predicted values and the measured values, the friction coefficient and the heat transfer coefficient is preferred, Prediction of wellbore temperature and pressure distribution during the balance period, gas injection and gas production of the gas reservoir of Xiangguosi gas storage. The results show that the relative error between the predicted temperature value and the measured temperature value is less than 5%, the relative error between the predicted pressure value and the measured pressure value is less than 2%, and the prediction accuracy is acceptable. It can meet the demand of prediction, and can reduce the times of continuous coiled tubing test and the risk caused by operation. It can provide basis for optimization of injection and production plan and evaluation of wellbore pressure in gas storage wells.
