吉林油田地域分布广,各地区地质情况复杂,而且各地区差异很大,油层埋藏深浅不一,固井施工设计要求各不相同,主要解决的固井技术难点也不同。本文针对吉林油田浅层气井的地层岩石构造情况,及钻井时出现的复杂情况确定合理的固井水泥浆体系,优选晶体膨胀水泥浆体系改善水泥浆性能,提高该区块固井质量,增加油气产能。
Geological distribution of Jilin Oilfield is broad. Geological conditions in all regions are complex. In addition, there are great differences among different regions. Different depths of oil layers are buried, and cementing construction design requirements are different. The main difficulties in cementing technology are also different. In this paper, aiming at the formation rock structure of shallow gas wells in Jilin Oilfield and the complicated situation during drilling, a reasonable cementing slurry system is determined. The crystal expansion slurry system is recommended to improve the performance of cement slurry, improve the cementing quality of this block and increase the oil and gas Production capacity.
