Research Design and Development of an Intelligent Disconnect Tool used in oil and gas exploration

该公司正在研究和开发一种新型的智能井下分离工具（I-DISC），该工具可以在现有最先进方法的一小部分时间内完成井底组合的分离和提取。在油气勘探过程中，由于井眼清洁不良以及随后的岩屑堆积，底部钻具组合（BHA）可能会卡死。随着定向钻井项目可能超过10公里，问题变得越来越普遍，成本也越来越高，因为石油勘探公司希望从直到最近还不具有商业可行性的油藏中开采石油储量。在电缆系统不容易使用的情况下，现有的断开BHA的方法既费时又容易出错。在开发和勘探钻井中，当BHA卡在井中时，钻机、设备和支持成本超过100万美元/天，成本相当可观。智能断开工具将在自主监测钻井参数后，在这种情况下提供钻杆分离，从而实现可控和省时的解决方案。

The company is looking to research and develop a novel intelligent down the hole disconnecttool (I-DISC) which would provide disconnection from the bottom hole assembly andextraction in a fraction of the time of the existing state of art methods. During oil and gasexploration the bottom hole assembly (BHA) can become stuck/jammed due to poor cleaningof the hole and subsequent build up of cuttings. With directional drilling programmespotentially exceeding 10km, problems are becoming more common and expensive as oilexploration companies look to access difficult to extract oil reserves from reservoirs whichuntil recently were not commercially viable. Existing methods of disconnecting the BHA arecrude and prone to error where wireline systems cannot easily be employed. In developmentand exploration drilling, the costs when the BHA becomes stuck down the hole areconsiderable with rigs, equipment and support costs exceeding $1M per day. The intelligentdisconnect tool would provide the separation of drill pipe in such instances after autonomousmonitoring of drilling parameters, thus effecting a controlled and time efficient solution.
