METHOD FOR EVALUATING INFLUENCE OF MOTHER ROCK ON RESERVOIR PHYSICAL PROPERTIES

摘要

Disclosed is a method for evaluating the influence of mother rock on reservoir physical properties, the method comprising the following steps: 1) selecting, according to the rock type distribution of a target reservoir, a typical rock sample, and cutting same into blocks; 2) putting the rock sample into a basket of a reaction kettle, adding acid liquor and carrying out sealing; 3) carrying out temperature programming to a target temperature and pressure, and reacting for 36-72 h at a constant temperature and a constant pressure; and 4) after the reaction is completed, naturally cooling the reaction kettle, and taking out the sample for analysis. The cut shape of the rock sample is one of a cube, a cuboid or a cylinder. The method provides a new concept for analyzing the influence of mother rock on reservoir physical properties, and can lay a foundation for exploration of high-quality reservoirs by using data such as type and content of rock debris in a research area in combination with actual temperature and pressure conditions.
