Abstract
Summary
In this work we marked one of the approaches to the determination of reservoir properties with control of saturation by method of NMR on the example of one well:
On the basis of the material composition has been determined four major lithological types of rocks of Bazhenov Formation: 1. Pyritized argillite 2. Phosphate rock 3. Limestone fine-crystalline 4. Clay-siliceous rocks. For holding reseach we selected two cores from the same place. One of them was used for determining the residual water by method of Dean-Stark, the second was researched by methods of NMR and gas saturation.
As a result, we have the following conclusions:
- From the viewpoint of elaboration lithological types of 2 and 4 are more interesting because they can store and transport fluid.
- Lithological type 4 is the most interesting for us because it is capable to store fluid, but its capacity of transporting is unknown according the results of method of NMR volume of mobility of fluid is small
