板70-18区块油井深度大、油稠、含蜡高,生产中易发生蜡堵情况,为保证井筒畅通需定期采用热洗车组洗热井筒,确保油井正常生产。但热洗效果不理想,洗井后油井产量下降,含水恢复期长,严重的甚至造成检泵作业,费用高,损失大。通过分析论证和实践得出结论,油井完全可以通过用井口连水套炉的自洗流程来解决这一问题,即节约了成本,也大大提高了生产时率,效益得到增加。
Block 70-18 Block oil well depth, thick oil, waxy high, prone to wax blockage in production, in order to ensure the smooth flow of wellbore need to regularly wash the hot wash car wash tub, to ensure the normal production wells. However, the effect of heat-washing is not satisfactory. After the well flushing, the production of oil wells is decreased and the recovery period of water is long. Severe pump operation even results in high cost and large loss. Through the analysis and demonstration and practice concluded that the well can be completely through the wellhead with water jacket furnace self-cleaning process to solve this problem, which saves costs, but also greatly increased the production rate, the benefits have been increased.
