... Abstract Formation micro imager is applied in geological investigation of borehole which can provid much more properties than core sample collection. In this paper, the photogrammetic method is discussed during the lab test based on images. Photogrammetric technology is the technique...

... formation. However, the borehole stability is a big problem through several pilot gas drillings. In this paper, combined lab investigations with pilot drilling information analysis, it is found that the complex geologic conditions and drilling operations lead to at least four kinds of borehole instability...

... Abstract Referring to the casing perforated wells and based on linear-elastic theory, the stress around borehole and perforations of deviated well is analyzed and the influence of stress distribution around borehole and perforations is also fully considered. In the paper, the conception of two...
