COMPLEX FOR exploration for oil and gas in complicated constructions area with developed salt-dome tectonics mapping ROOF AND SALT salt deposits (COMPLEX) AND COMPUTER TECHNOLOGY CENTER (CTC) FOR HIM

摘要

1. The complex includes: the system of geophysical studies of wells (GIS), a network of geophysical profiles, in which deep drilling wells (wells of deep drilling - parametric wells) are used to obtain data in a common coordinate space using data from seismic well logging (SK) electric logging (EC) and density logs (PC) in them, and a network of geophysical profiles for the readings (measured data) measurement units seismic, electromagnetic, gravity - and magnetic, with geoelectric parameters of the function derived from measurements of electrical, depend on the parameters of the medium and are designed as a combination of temporal and spatial derivatives of the field of formation, characterized in that the complex is equipped with measuring units using surveillance systems: 2D installation and / or 3D seismic survey in the wide-execution and block psevdodiagonalnoy observation system in which all of the excitation line ( LV) and receive line (PL), located across the strike of the salt structures, forming a seismic network, the installation of electrical AB-MN-n in the emergence of sensing modification with measurements of parameters of induced polarization (AP-CP) plated grounding, installation of high-precision gravity and installing magnetic survey, measuring devices placed near the parameter well studied on the basis of GIS data with prior data to determine the territory of the salt tectonics developed in the study area, while in the electrical installation of AB-MN-n in the AP-VP modification of measured data is calculated along seis
