METHOD OF SPACING OF THE PROSPECTING, DEVELOPMENT AND PRODUCTION WELLS ON THE OIL AND NATURAL GAS FIELDS BASED ON THE THREE-DIMENSIONAL GEOLOGIC MODEL Russian patent published in 2007 - IPC G01V11/00 

FIELD: oil-producing industry; natural gas industry; methods of spacing of the prospecting, development and production wells on the oil and natural gas fields based on the tree-dimensional geologic models.

SUBSTANCE: the invention is pertaining to the petroleum geology and may be used for optimization of spacing of the prospecting and production wells on the tested field. Contents: conduct the seismic surveye works, the well-drilling with the core samplings from the target stratums, the geophysic studies of the wells, the wells testing. On the basis of the total data acquisition reveal the types of the geologic sections with the various oil-and-gas productive properties for the target stratums. Draw the prognostic seismic maps of spreading of the revealed types of the section along the area under the study. The produced map they transform into the digital format considering the arguments of the trustworthiness of the forecasting technique. On the basis of the digital map reconstruct the lithologic (lithofacies) model of the stratum or the field. On the basis of the produced model they plot the models of the porosity and the oil-and-gas saturation of the rocks. On the received geologic model conduct the assessment of the resource base of the field, determine the places of the possible sinking the wells. On the basis of the whole information present in the model they select the optimal from the geologic-ecologic-economic point of view way to arrange the new wells. The technical result of the invention is: the reduced terms of the operations, the decreased negative effect on the environment.

EFFECT: the invention ensures the reduced terms of the operations, the decreased negative effect on the environment.
