This article presents the express-method for obtaining the initial data on physical-chemical properties of in-place oils under field conditions using the original downhole sampler – ‘pentometer’. Using the device, we can produce not only a downhole sampling, but also its researching in the field with minimum of support equipment and gaging instruments. The pentometer can determine five parameters: gas-oil ratio, formation volume factor, formation and separated oil density, separated gas density. This device is a freestanding and has tested in the field methods; it is enabling to obtaining a large amount of samples. This device provides field development control and evaluation of technologies used under field. Express researching method using the downhole sampler - pentometer is a part of under field, laboratory and analytical methods for researching physical-chemical properties of reservoir fluids. Developments are protected by copyright certificates and can be used in a program of import substitution.
