摘要
井下作业技术作为石油和天然气勘探开发的重要工程技术和手段,近年来取得了显著的进步,做出了重要贡献。随着钻井技术的不断发展,井眼越来越复杂,对井下作业提出了更高的要求,以前单凭经验来进行操作的井下作业已经不适时宜了,经常造成各种井下管柱事故。井下作业管柱受力分析软件在设计过程中用于预测某些潜在危险,尽量避免作业事故发生,使得设计更为合理、切实可行;在作业过程中用以分析某些事故原因,以便针对性地来处理问题,节约事故处理时间,降低作业费用,提高作业效率。该软件可以对起下管柱过程、压裂过程和打捞过程等的管柱力学状态进行计算,并对油管的长度进行初步优化。该软件无论是对作业前的室内设计还是现场作业过程中的作业管柱受力分析都有一定的指导意义,在大港、长庆等油田得到了初步应用。
As an important engineering means of oil-gas exploration and development, downhole operation has made prominent progress in recent years. With the continuous development of drilling technology, the boreholes become more and more complex, which presents higher requirements for downhole operation. Previous operation that was only dependent on the experience has been behind the times and often resulted in various downhole accidents. In the design process, we use the mechanical analysis of downhole operation pipe strings to predict some potential dangers, so as to prevent accident and make design more rational and feasible. During the process of operation, we use it to analyze some accident cause, so that pertinent measures can be taken with less time and cost and higher efficiency. The software can be used to calculate mechanical state of pipe string in the course of trip in/out, fracturing and fishing etc, and optimize tubing length preliminarily. The software has guiding significance in mechanics analysis of downhole service pipe strings, no matter indoor design or on site operation. And it has been applied in Dagang and Changqing oilfield etc.
