【摘要】：目前常用的提速工具经济性评价方法都是在钻后进行评价,不能为特定井段优选提速工具提供依据,为此,以单位进尺成本为准则,提出了一种钻井提速工具经济性评价新方法。该方法首先结合提速工具性能指标进行钻前预测,然后利用提速工具第一趟钻的实钻参数,对后面几趟钻的经济性进行随钻预测,并根据单位进尺成本预测最后一趟钻应用提速工具的经济性,完钻后计算应用提速工具井段的钻井总费用,并与邻井未应用提速工具相同井段的钻井总费用进行对比,以确定提速工具的经济性。实例验证及研究结果表明,钻井提速工具经济评价新方法可指导特定井段提速工具的优选和快速及时地预测提速工具的经济性。
[Abstract]:At present, the commonly used economic evaluation methods of speed-raising tools are evaluated after drilling, which can not provide the basis for the optimal selection of speed-raising tools in a particular well section. Therefore, the unit ruler cost is taken as the criterion. A new economic evaluation method for drilling speedup tools is proposed. In this method, the pre-drilling prediction is carried out with the performance index of the speedup tool, and then the economy of the next few drills is predicted by using the real drilling parameters of the first drill of the speed-raising tool. According to the unit scale cost, the economy of the last drilling and the application of the speed-raising tool are predicted, and the total drilling cost of the section with the speed-increasing tool is calculated after drilling, and compared with the total drilling cost of the same section of the adjacent well without using the speed-raising tool. To determine the economy of the speedup tool. The results show that the new method of economic evaluation of drilling speedup tools can be used to guide the optimal selection of speed-raising tools in a specific well section and to predict the economy of speed-raising tools in a fast and timely manner.
