摘要
长庆华池油田随着开采程度的不断提高 ,水淹程度提高 ,油层压力、温度不断变化 ,油田结垢日趋严重。通过垢型特征分析 ,结合注入水、地层水化学资料及模拟试验 ,揭示了结垢机理 ,讨论了结垢分布特征及其对生产的危害 ,分析了结垢治理配套技术的室内及现场效果 ,探讨了解决该油田结垢危害的技术发展方向。
Scale buildup is increasingly serious along with the deepened production, increase of wateredout and continuous change on pressure and temperature in oil reservoirs in Huachi oilfield of Changqing. Scaling mechanism of Huachi oilfield is revealed through the study on scaling characters, chemical data of formation water and injection water and simulating test. Distribution feature of the scale and its damage on production in the field are discussed. The results in laboratory and field effect of a set of antiscaling technology are analyzed. Then the developing tendency of the technology for solving the scale damage completely in this oilfield is discussed.
