普光气田开发井地质情况和井身情况比较复杂,普遍采用了固井新技术、新工艺,声幅变密度法固井质量解释存在诸多困难。本文通过分析井斜、低密度水泥浆固井和快速地层等诸因素对测井资料的影响,研究普光气田的固井质量解释方法,确定了普光气田生产套管固井质量解释标准。
The geological conditions and wellbore situation of the development wells in the Puguang Gasfield are quite complicated. There are many difficulties in applying cementing new technologies, new techniques and acoustic amplitude-variable density method to cementing quality. In this paper, by analyzing the influence of wellbore inclination, low density cementing and rapid formation on logging data, the cementing quality interpretation method of Puguang Gas Field is studied and the cementing quality interpretation standard of production casing in Puguang Gasfield is determined.
