Some Misconceptions in Pile Insertion Analysis of Offshore Platforms in Shengli Chengdao Oilfield

Abstract:

According to some actual cases of pile insertion analysis, combined with specialty norms and principles of soil mechanics in this paper, a few common misconceptions in pile insertion analysis of offshore platforms in Chengdao Oilfield are summarized. Type of common misconceptions, causes and adverse effects are analyzed, and countermeasures are put forward to correct misunderstandings and improve the accuracy of pile insertion calculation and analysis. Cases of analysis errors can be easily found because of unclear soil layer classification, difficultly recognized geotechnical properties, inaccurately divided layer uniformity, inadequately considered structure and soil interaction responses, etc. in offshore platforms pile insertion analysis, thus many unnecessary losses appear in oilfield production. By improving survey quality, using a variety of means of investigation, paying more attention to soil layer uniformity in well field, properly evaluating strength of laminated soil, doing anti-slip platform evaluation when pile is inserted too shallow, etc. can reduce errors effectively.
