Title: Method of oil production
Inventor: PODOBED V S
IPC: E21B43/16
Filed: 2000-01-13
Granted: 2001-01-27
Abstract: FIELD: oil and gas producing industry; applicable in development of deposits of various structure types and also of depleted and difficult-to-recover oil reserves. SUBSTANCE: method includes opening of oil formation by system of producing and injection wells and treatment of producing formation by pressure fluctuations produced by downhole plants with amplitude not in excess of tensile fatigue strength of rock. Producing formation is opened through 50-80% of its thickness. Pressure fluctuations in the form of acoustic flux are produced in oil formation with the help of downhole acoustic devices immersed into injection wells. Device is immersed into injection wells to depth of formation opening after filling of these wells with oil and attaining of natural formation pressure. Excessive pressure is built-up of value ensuring calculated oil flow rate and maintenance of formation pressure at natural level. Oil is recovered up to pressure drop not below saturation pressure. Formation pressure is restored by injection of dry gas to gas cap. Downhole acoustic devices are gradually raised as the formation is progressively treated. EFFECT: higher oil recovery, reduced cost price oil production, provision of displacement of residual oil from low-productive formations, efficient use of method on deposits with different structures of reserves. 2 cl, 1 tbl, 2 ex

Abstract: FIELD: petroleum processing. SUBSTANCE: method comprises heating feedstock in tubular furnace, holding cracking products in reaction chamber, and separating cracking products into gas, gasoline, and cracking residue. In particular, are determined weight concentration of hydrogen sulfide in cracking gas, raw material viscosity, and current value of cracking residue viscosity, after which viscosity decrease value (VDV) is calculated from relationship: VDV= 2.25*C- 3.6, where C is hydrogen sulfide concentration, wt %. From ratio of oil feedstock to VDV, minimal design viscosity of cracking residue is found taking into account difference between design and current values of cracking residue viscosity. Process parameters are then corrected by raising temperature of raw material stream at reaction chamber outlet or by lowering its intake at this chamber inlet. Invention allows optimal selection of cracking conditions to be ensured by means of express-mode determination of optimal viscosity decrease coefficients and, correspondingly, minimal values of viscosity of cracking residues. EFFECT: avoided large volume of experiments needed to process control. 1 tbl, 15 ex
