成功地钻探大位移井,钻井岩屑携带效率是非常重要的因素之一。近期科研人员在开发模拟大位移井钻屑流动瞬态模型过程中,开发研制了一种测量流过振动筛岩屑流量的测量仪器,它可测定返出的钻屑量,与钻井产生的岩屑量进行比较,再与系统采集到的其它钻井参数进行综合考虑,便可评价井眼的净化程度。这样有助于钻井工程师确定循环环空的合适时间,从而避免不必要的循环,以便节约钻井成本且实现优化钻井。
Successful drilling of large displacement wells, drilling cuttings carrying efficiency is a very important factor. Recently, researchers in the development of simulated displacement wells drilling flow transient model developed a measure of flow through the vibrating screen debris flow measuring instruments, it can measure the amount of return drilling and drilling rock The amount of debris to compare, and then collected with the system to consider other drilling parameters, we can assess the degree of wellbore purification. This helps the drilling engineer determine the proper time for the annulus to avoid unnecessary cycles in order to save on drilling costs and optimize drilling.
