一种煤层气井无动力井底碎化煤粉助排装置所属
本技术涉及了一种煤层气井排采设备组件,尤其涉及一种煤层气井无动力井底碎化煤粉助排装置。
技术介绍
煤层气是目前我国开采的重要非常规油气资源之一。煤层气的开发不仅可以为国家提供清洁能源,缓解我国清洁能源紧张的局面,而且可以减少煤矿瓦斯事故,降低温室气体排放。我国煤层气开发的地质条件极为复杂,煤储层较脆,易产生煤粉、煤焦,进入井筒的煤粉易造成埋泵卡泵,导致排采中断致使煤层气井产气量降低甚至不产气,大大缩短了泵的寿命,严重影响了煤层气的生产和经济效益,造成了直接的经济损失。目前井筒内煤粉排出是通过复杂的地面装置增加井液的流速携带而排出,无法解决大颗粒煤粉的沉积和卡泵的问题。目前尚没有一种有效的装置可以实现无动力碎化煤粉颗粒助排煤粉,对煤层气井稳定连续排采造成了较大的阻碍,严重影响了煤层气的连续排采与产出经济效益。
