注水开发过程中,部分区块受储层水敏、盐敏等敏感影响,近井地带粘土膨胀、运移,堵塞油层孔道,造成油层吸水能力变差。为了提高高压注水井的注水效果,提高低渗透油层的产量,实施点滴加药工艺技术措施,改善以往的集中加药的设备体积过大,加药设备能耗过大,导致油田注水成本增加的问题,提高点滴加药注水的效果,满足高压注水井的技术要求。 During waterflood development, some blocks are sensitive to water sensitivity and salt sensitivity of reservoirs, and clay near the wellbore expands, migrates and blocks the oil and gas channel, resulting in poor water absorption capacity. In order to improve the water injection effect of high pressure water injection wells, increase the yield of low permeability oil layer, implement the technical measures of drip dosing process, improve the volume of previous dosing equipment, increase the energy consumption of dosing equipment and increase the cost of water injection Problems, improve the effect of drip dosing water injection to meet the technical requirements of high pressure water injection wells.
