The DST-3 type inter-bor6hole acoustic sounding and borebole acoustic oil-mining system is characterized by hihg resolution ratio and high detedboility whert used in itherborehole tomographic imagery and is noted for high power and Wide action range when used in borebole shaking oil mining of the oil reservoir. When this system was tested in Gao 104-5 well aam Gao 105-5 well of ths Jidong oil field, telatively high-quality inter-borehole data of the deep oil reservoir were obtained with borehole distance of 210 m and at the depth of 1854. 1 m-1890 m. Aftor CT processing, the profile of inter-borehole acoustic tomographic imagery was consttucted. The elimination of plugging by downhole acoustic source shaking was successfully Carried out in 1867.6m-1884.8m oil-bearing formation of Gao 104-well.The results of the tests have proved the reliability and practicality of this system and shown that the system will play a special role in the development and exploitation of oil and gas fields.
