摘要:
提压增注是提高注水井注水量的重要手段之一。矿场实践表明,当注水井近井地带存在污染时,注水井实际井口注入压力超过方案设计的最大井口注入压力后,可以进一步提高注水量,且保证安全生产。通过开展注水压力优化研究,首次应用霍尔曲线分析注水井提压增注的可行性。通过霍尔曲线可以快速计算表皮系数和附加压降,修正注水井合理最大井口压力,明确提压增注幅度。该方法的优点是只需要井口注入压力和注水量等少量生产参数,资料易于获取,且霍尔曲线是一种积分函数,其计算结果误差更小,对相似油田的注水压力优化有一定借鉴意义。
Abstract:
Water injection by increasing pressure is one of the important means to increase the water injection rate of water injection wells. The actual data from the oilfield demonstrates that when there is pollution close to the injection well area,the water injection rate can be further increased and safe production can be ensured once the actual injection pressure of the water injection well exceeds the maximum injection pressure designed in the scheme. The Hall curve is used for the first time to examine the feasibility of water injection by increasing pressure in water injection wells by performing the optimization study of water injection pressure. The suitable maximum pressure of the water injection well can be corrected,the skin coefficient and additional pressure drop can be promptly estimated,and the range of pressure increase can be determined using the Hall curve. The benefit of this method is that it only requires a few simple production parameters,such as wellhead injection pressure and water injection volume. Furthermore,because the Hall curve is an integral function and its calculation result has a smaller error,it can be used as a reference for optimizing water injection pressure in similar oilfields.
