新疆油田风南10井钾钙基聚磺钻井液技术应用

Application of Polysulfonate Drilling Fluid Based on Potassium and Calcium Technology in Well 10 of Fengnan in Xinjiang Oilfield

综述了钾钙基聚磺钻井液在新疆油田风南10井的具体应用效果。钾钙基聚磺钻井液是一种结合钾基钻井液、钙基钻井液、聚合物钻井液以及三磺钻井液共同功效的一种较为重要的钻井液之一,对泥岩、砂砾岩、煤层、页岩都具有良好的应用效果,可大大减少钻井液的成本和减少井下复杂情况的发生。

Polysulfonate drilling fluid based on potassium and calcium is one of the comparatively important drilling fluids,which is a combination of potassium base drilling fluid,calcium base drilling fluid,polymer drilling fluid and three sulfonated drilling fluid.Polysulfonate drilling fluid has good application effect for mudstone,sandstone,shale and coal and can greatly reduce the cost of drilling fluid and the occurrence of complicated conditions in the wells.This paper studies the application effect of polysulfonate drilling fluid base on potassium and calcium in well 10 of Fengnan in Xinjiang oilfield.
