营13区块浅层水平井钻井液技术

Drilling Fluid Technology of Shallow Horizontal Well in Ying 13 Oilfield

营13区块油气资源丰富,开发前景广阔.前期使用聚合物钻井液施工中复杂情况时有发生,严重制约了该区块的开发进程.通过对处理剂进行优选,研发了强抑制润滑钻井液体系配方,该体系在营13区块进行了应用,井身质量良好,机械钻速明显提高,为营13区块安全及高效钻井提供了有力的技术保障.

Oil and gas were very rich in Haqian Oilfield, and development prospects was broad. Down-hole troublesome condition occurred frequently while the polymer drilling fluid was applied during the course of drilling ago, and the development progress was seriously restricted. After treating- agent was selective preference, high inhibition and lubrication anti- caving drilling fluid was researched and developed. After the drilling fluid was applied in Ying 13 Oilfield, the wellbore quality was very good, and rate of penetrate was improved evidently. At last, it provided technology support to drill safely and high effectively in the oilfield.
