Sinochem News recently, a kind of oil-water well plug removal tool developed by Henan Oilfield, the rotary jet, has obtained the national patent authorization
.
The tool enriches the technical means of unblocking oil and water wells, and improves production efficiency while increasing production and injection
Usually in the production process of oil and water wells, due to scaling, wax deposition, mechanical impurity precipitation in the pores of the rock formation, or the invasion of drilling fluid, workover fluid and solid phase particles in the formation during drilling and workover, the formation in the near-wellbore zone will Different degrees of blockage occur, resulting in a decrease in formation permeability, reduction in oil well production, poor water absorption in water wells, and even shutdown of oil and water wells
.
In response to the above problems, the company's engineers and technicians developed a rotary jet
.
The device uses jet liquid to impact the blockage of the formation, and uses high-pressure water to generate hydraulic waves, high-frequency oscillating jet shock waves and ultrasonic waves to act on the formation comprehensively, so as to achieve the purpose of unblocking the wellbore and the formation near the wellbore
At present, the device has been used in 6 wells, the jet intensity is above 3 MPa during construction, the average validity period is 112 days, and the cumulative oil increase is 637 tons
