Research on Drilling Fluid Technology for WFSD-2 Hole of Wenchuan Earthquake Fault Scientific Drilling Pro-ject
摘要
Abstract
The geological conditions were extremely complicated with poor wall stability in WFSD-2 hole drilling construc-tion of Wenchuan earthquake fault scientific drilling project.Due to the water-sensitive formation of mineral water swelling, broken strata and stress release, the hole wall necking, collapsing and leakage happened many times.Through the adjust-ment and maintenance of the formulation, parameters, and solid control, LBM-GLA drilling fluid system with a low vis-cosity synergy powder and modified asphalt as the main raw materials was adopted in the construction;the above problems were successfully solved.This article mainly describes the use and maintenance of drilling fluid in each section of WFSD-2 hole.关键词
