Introduction

In order to simulate dynamic damage on hydrocarbon reservoir under wellbore condition and evaluate efficiency of drilling fluid for formation protection, we developed a new intelligence dynamic filtration apparatus in HTHP—JHMD-Ⅰ. It took a closed circulation line, instead of the magnetic stirring structure of the traditional instrument, to simulate the damage on core during drilling, and simulate damage on the end face of core in the wellbore condition. In addition, it has longer service life.

The apparatus is a very important part of a research, which was award the second award of national science and technology progress.

Application

1. can simulate damage on the end face of core in the wellbore condition;
2. can optimize drilling fluid and completion fluid;
3. can research on reservoir protection technology;
4. applied to filtration test of drilling and completion fluid;
5. applied to dynamic prevent collapse test of shal
