Linear ultrasonic transducer array

Abstract

The invention provides a linear ultrasonic transducer array, which comprises a housing 1, a roller 2, an ultrasonic transducer frame 3, an ultrasonic probe array 4, a support column 5 and fixed rods 6. According to the linear ultrasonic transducer array, the problems of yield reduction, injection reduction and the like caused by the aspects of low permeability, mud contamination, chemical agent blockage, operation contamination and the like of an oilfield can be effectively solved, and by an ultrasonic oil reservoir treatment technology, the yield increasing cost of an oilfield enterprise can be effectively controlled, the input-output ratio can be increased, and good economic and social benefits can be created.

Description

technical field [0001] The invention relates to an oil layer processing device, in particular to a linear ultrasonic transducer array. Background technique [0002] In the production of oil wells, the medium and high porosity and permeability formations have a certain production capacity at the initial stage, but with the prolongation of the production time, the production declines rapidly. In the water injection wells, the wells with no or reduced water absorption capacity are generally treated; Seriously polluted oil and water wells, that is, oil wells that are blocked due to scaling and wax formation, or oil and water wells that have been polluted during other operations; oil and water wells that have significantly reduced production capacity due to the high clay content in the oil layer. With the gradual exploitation of oil, nearly The permeability of the bottom of the well is reduced, and the clogging of the underground oil layer causes the clogging of the oil well, w...

[0002] In the production of oil wells, the medium and high porosity and permeability formations have a certain production capacity at the initial stage, but with the prolongation of the production time, the production declines rapidly. In the water injection wells, the wells with no or reduced water absorption capacity are generally treated; Seriously polluted oil and water wells, that is, oil wells that are blocked due to scaling and wax formation, or oil and water wells that have been polluted during other operations; oil and water wells that have significantly reduced production capacity due to the high clay content in the oil layer. With the gradual exploitation of oil, nearly The permeability of the bottom of the well is reduced, and the clogging of the underground oil layer causes the clogging of the oil well, which in turn reduces the production of the oil well and leads to an increase in the water content of the crude oil
