霍10井区大倾角地层自然造斜规律探讨与防斜打快对策

STUDY OF NATURAL DEVIATING RULE AND METHOD OF DEVIATION CONTROL AND FASTER PENETRATION FOR BIG DIP ANGLE FORMATION IN WELL HUO 10 BLOCK

新疆油田霍 10井区大倾角构造由于地层倾角大、地层各向异性强、地层自然造斜性强、井身质量差和机械钻速低是该地区钻井工程突出的问题。文章从理论上探讨了地层自然造斜力、钻具组合对井身质量的影响 ,针对霍 10井区高陡大倾角构造的地质特征 ,分析研究了可用于该研究区域的防斜打快的方法和技术 ,对霍

The poor hole quality and low penetration rate is the big problem of drilling engineering since the formation dip angle is big, the formation anisotropy great, and the formation natural deviating strong for the big dip angle structure in well Huo 10 block of Xinjiang Oil Field. The article theoretically discusses the natural deviating force of the formation and the influence of the make-up of string on the hole quality. Aiming to the geological features of the high steep and big dip structure in well Huo 10 block, the article analyzes the methods and techniques for deviation control and faster penetration that may be applied in this area. The article has the guiding role for deviation control and faster penetration in well Huo 10 block.
