摘要
The technical requirements of drilling and completion fluid according to XinjiangLuliang reservoir characteristics and construction techniques of horizontal drilling,new free clay phase reservoir protection drilling and completion fluid technology is studied,and for the first time in Luliang Xinjiang,the 35 wells are applied widely,and good results were achieved.The technology,the only effective solution to the suspension of water-based drilling fluids,carrying rocks,to meet the demand for drilling,and minimize solid,liquid relative reservior damage,also broke through the limitations of traditional reservoir protection technology drilling and completion fluid contamination near the borehole wall strata broken plastic deplugging,lift shaft wall cake,so continuity of reservoir protection drilling engineering and well completion process is realized,forming a reservoir designed drilling and completion fluid technology.The field application of the technical formula is simple,easy to maintain,and the effect is obvious,which greatly improved reservoir permeability recovery value,so good economic and social benefits are achieved.
