摘　　要：中原油田气井地层能量日渐衰弱 ,致使措施入井液大量漏失 ,凝析气在孔喉中凝析而产生“液锁”效应等损害地层的因素。针对这种情况 ,采用了热化学解堵技术 ,通过室内试验研究了热化学解堵剂配方以及配套施工工艺 ,应用现场后取得了明显的增产效果。The energy of gas reservoir in Zhongyuan oilfield have fallen into a decline.For this circumstance the vicinity-well stratum will be easily contaminated in the course of increasing production measure because of the liquid-lock phenomena resulted from the leakage of inflowing fluid or condensation from hydrocarbon.Therefore,the technique of thermochemistry plug-release was studied by indoor experimentation.The application shows that the thermochemistry plug-release technology has an effective increasing production results.
