摘要：
Heat cleaning of oil pumping well make formation leakage and damage serious in water - sensitivity and low formation pressure, so the shielding temporary plugging technology is adopted. By lab. test, we select DCX - 01 temporary plugging agent and apply in the thermal well cleanout. The experiments of 4 wells in Wei2 fault block show that the loss of crude oil is decresed by 298t compared with general heat cleaning, and good economic benefit has been obtained. Meanwhile, the technology solves the problem of formation damage.
