In paper were considered the structure of Kuryino-Patrokovskoe area, comparison of all available prospect drilling data in the studied territory and justification of the forecast of pressure anomality by drilling gas deposits, also gas-water contact forecast and gas content prospect of Kuryino-Patrokovskoe deposit.
Materials and methods
Graphic method of gas-water, water-oil and gas-oil contacts definition by pressure single measurement in bed.
Results
The understanding of similar distributionof pressure within one deposit gives us the chance of more correct laying of a gradient of reservoir pressure at a design stage at a well arrangement in a arc part or on wings of structure where the gradient of pressure will be much less rather arc part and, respectively, here it is necessary to apply lighter drilling agent.
Сonclusions
This work is carried out in the mode of keen necessity in obtaining the general understanding about a structure and gas content of the territory of the Kuryino-Patrakovskaya area for a possibility of better and accident-free drilling, as a result, receiptof more complete and reliable information for estimation of reserves and development of fields. At interpretation of seismic prospecting data the understanding about differentiationof zones with various provision of gas-water contact and pressure will give the chance to trace violations in sites which structure raises doubts. At further drilling of the area and accumulation of qualitative reliable data it will be possible to receive practical confirmation of the applied theoretical bases for development of more exact and confirmed model.
