摘要

摘要: 北部湾地区地质条件复杂,钻井难度大,结合北部湾地区钻探的实际情况,通过对影响水基钻井液重复利用因素的分析,对废弃钻井液的粒度分析和性能检测制定了一套成熟的固相控制技术。通过检测废弃钻井液中固相颗粒粒径分布,优化固控设备的搭配和参数配置(尤其是振动筛筛布选择),选择离心机分离能力、布局和台数等,从而提高固相控制效率,达到有效净化废弃钻井液的目的;制定了一套合适的废弃钻井液处理方式:先检测回收的废弃钻井液性能,然后通过固控设备来净化废弃钻井液,合理配制新浆量进行稀释处理废弃钻井液,使钻井液性能满足下一口井或井段的开钻要求,节省了材料成本、人工成本和运输成本。北部湾水基钻井液固相控制与重复利用技术在北部湾地区29口开发井进行了成功应用。

Abstract: Formation geology in the Beibu Gulf area is complex,making drilling operation very difficult.Solids control plays an important role in the success of drilling in this area.A complete set of solids control technology has been developed through laboratory analyses and experiments.The configuration and parameter specifications of solids control equipment (especially the selection of the screen cloth for shale shakers) are optimized through inspection of particle size distribution of the water drilling fluids.The treatment capacity,configuration and number of centrifuges are carefully determined to enhance the efficiency of solids control.In the treatment of the waste drilling fluids,the properties of the waste drilling fluids are firstly measured,then the waste drilling fluids are cleaned through the solids control equipment,and some new drilling fluids are prepared for use with the cleaned waste drilling fluids.In this way the properties of the drilling fluid satisfy the needs for the next hole section or the next well,and the mud cost,labor cost and transportation cost are all reduced.This technology has been successfully used on 29 wells in the Beibu Gulf area.
