Introduction

Tight oil exploration is an important area of unconventional petroleum exploration in the world. The potential of tight oil resources in China is large, in order to adapt to China's unconventional oil and gas Development needs, specially formulated this standard, to regulate and guide the development of China's tight oil exploration and development for policy formulation, scientific research, evaluation of the results in accordance with. Tight oil geological evaluation method

1 Scope

This standard specifies the geological evaluation of tight oil content, parameters and methods. This standard applies to the tight oil geological evaluation.

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. SY/T 5336 core analysis method Geochemical evaluation of SY/T 5735 terrestrial source rocks SY/T 5838 onshore oil and gas proved economically recoverable reserves evaluation rules SY/T 6285 method for reservoir evaluation Determination of rock porosity and permeability under SY/T 6385 overburden

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Tight oil tightoil Tight sandstones that accumulate in the overburden matrix with a permeability less than or equal to 0.1 × 10-3μm2 (air permeability less than 1 × 10-3μm2) Oil in tight carbonate or other reservoirs, or oil with a non-heavy oil flow less than or equal to 0.1 mD/(mPa · s). Note. In the vicinity of the reservoir, the organic-bearing source rocks have no natural capacity or natural capacity below the lower limit of commercial oil production, but under certain economic conditions and technical measures Applied to obtain commercial oil production. 3.2 Overburden matrix permeability in-situmatrixpermeability Permeability measured with net overburden pressure without fractured core (matrix). 3.3 Dessert area sweetarea Source rock, reservoir and engineering mechanics quality configuration is good, through the horizontal well, reservoir reconstruction can obtain the potential value of the development of tight oil distribution range.

4 tight oil geological evaluation

4.1 core sample screening and preparation 4.1.1 coring procedures and well core processing according to SY/T 5336 regulations. 4.1.2 Core sampling density Take 5 to 8 horizontal samples per meter and 2 to 3 vertical samples. 4.1.3 Rock sample preparation according to SY/T 5336 regulations.
