Abstract: Unlike the conventional perforation, advantage zone of reservoir can be implemented hydraulic jetting, finally microboreholes are formed between borehole and reservoir by high pressure jetting, and it can reach 100 meters far. On the basis of directional function of microboreholes, we’ll proceed to carry on the hydraulic fracturing technology, and then deep penetration artificial fractures are formed in the target formations, eventually to achieve the purpose of efficient reservoir reconstruction. The technology mechanism and procedure were introduced, the key parameters were optimized, and the rational treatments of volcanic formation were proposed according to the reservoir characteristic of Liaohe oilfield. The “directional deep penetration fracturing technology by hydraulic jetting” was applied successfully in the well of Liaohe eastern sag, and obtained high production. This technology was the first application in domestic oilfield, and brought a new method to develop volcanic formation including other difficulttoproduce reservoirs.
