Improvement of the method of definition of the current saturation of the exploitation objects according to impulse neutron-neutron logging data
Z. V. HeydarovFor increasing of productivity while using of the oil-gas fields, periodic definition of the current saturation along the section of the each exploitation well is one of important geological problems. The introduced article is devoted to this problem. As the researching object is VII horizon of Garadagh field, its geological features have been analyzed again on the basis of the latest data. In the article some rock examples of petrophysical parameters of VII horizon and frequency of distribution on the basis of well data have been compiled as a graphical form. In the article necessary formulas for VII horizon in the basis of INNL data of gas-saturation havebeen made, its physical features have been given and nomogramma for calculation of gas saturation has been compiled. Thus, the offered method for definition of current gas-saturation of exploitation objects in the basis of INNL data allows to determine oil-gas-saturation in the terrigenous collector with low mineralized layer water, to watch change of gas-water contact during exploitation process, to remove the influence of constructive elements of different phased filling of well shaft on the received result. Consequently, application of the offered method to three wells of Garadagh area where VII horizon has been opened and its mutual comparison with the other method has been carried out.
