METHOD OF SEISMIC TEST OF CHANGE OF CAPACITIVE PROPERTIES AND POSITION OF PRODUCTIVITY CONTOUR OF OIL AND GAS POOL PROCESS OF ITS DEVELOPMENT Russian patent published in 1997 - IPC

FIELD: seismic prospecting, optimization of production of oil and gas, increased discharge of wells by rational location of deep wells and creation of optimum mode of their operation thanks to increased interference stability and resolution of seismic data allowing to obtain reliable information on dynamic characteristics of examined object. SUBSTANCE: method includes excitation of elastic vibrations and recording of reflected waves by vertical geophones while developing profiles of MOV with generation of continuously referenced hodographs of OPV. Recording of seismic information is performed by assemblage of vertically oriented geophones fixedly placed in shallow wells by series of radial excitation profiles crossing in control point near operational well and crossing known contour of productivity of pools within limits of distances "blast-reception" providing for recording of information in optimal range of incidence angles of waves determining maximum degree of distinction of waves reflected from boundaries of productive pool and beyond its limits on basis of repeat observations, preliminary calibration against basic standard, their successive comparison and correction of operational mode. EFFECT: enhanced authenticity and accuracy of method. 4 dwg
