    摘要: The invention includes a method of increasing of the well rate of exploitation and recharge wells, comprising a means of decreasing the stress state in the well area by constructing of slot-like discharge key seats, wherein the slot-like key seats have a screw-like shape, wherein preliminary internal rock friction angles ρ are determined for a rock composing a productive strata, and a pitch of the slot key seat screw is selected such that the tangent of the angle of deviation of the slot surface from the φ vertical will be between tg(45−ρ/2)≧tg(φ)≧1/√3, where ρ—is the internal rock friction angle where the key slot is being made.

    摘要: A method of well treatment designed to enhance recovery of resources from the well. A solution with an alkaline pH greater than 8 is introduced into the well and allowed to react in the well for at least a minimum period of time. A neutral solution with a pH near 7 is introduced into the well and allowed to remain in the well for at least a minimum period of time. Finally, a solution with an acidic pH of approximately 1 is introduced into the well and allowed to react in the well for at least a minimum period of time.
