| Abstract: | The geologic structures are complex in Luo 68 block. Long mud making formation was penetrated during drilling. The hole size of the second spud was large and the barefoot interval was long in the second interval. The borehole was instability due to the faulted formation, slat beds and high pressure hydrocarbon reservoir in Shahejie formation. By means of optimizing polymer anticaving drilling fluid and sulphonated polymer anti-temperature and anti-caving drilling fluid, with the help of onsite drilling fluid techniques, good application effect was obtained. This technology provided support to drill other wells safely and high effectively in the oilfield. |
