樊142区块钻井液研究及应用

Research and Application of Drilling Fluid in Fan 142 Oilfield

通过对处理剂进行优选评价,研发了强抑制封堵钻井液,配合现场钻井液维护处理工艺,解决了该区块以往钻进过程中存在的起下钻遇阻、卡钻及电测不到底难题,保证了该区块定向井施工的顺利进行,提高了机械钻速,缩短了钻井周期,为该区块安全及高效钻井提供了有力的技术保障.

After treating - agent was selective preference, high inhibit and tormaUon seanng, unmng ~,u^u was researched and developed. The following down - hole troublesome condition was solved, which included blockage during tripping, drill pipe sticking and badly electronic logging occurred. The drilling was smooth under the help of onsite drilling fluid maintenance and handling techniques. The rate of penetration was raised and drilling period was shortened. At last, it provided technology support to drill well safely and effectively in the oilfield.
