چکیده
The present study has investigated drilling problems and practical solutions regarding them. It is almost certain that problems will occur when drilling a well, even in the most carefully planned wells. For example, in areas where similar drilling methods are used, pitting problems may be reported where there were no such problems before. Because the formations are heterogeneous. Therefore, two wells near each other may have completely different geological conditions. In well planning, the key to achieving successful objectives is to design drilling programs based on anticipation of possible wellbore problems rather than caution and containment. Drilling problems can be very costly. The most common drilling problems include pipe sticking, loss of circulation, hole deviation, pipe failure, formation damage, hole cleaning, H۲S and shallow gas formation, and equipment and personnel problems. Understanding and predicting drilling problems, understanding their causes and planning solutions are essential for overall cost control and successful reaching of the target area. Efroni base fluids have entered the drilling industry since the beginning of ۲۰۰۰, due to their unique properties, they can solve many drilling problems, especially in drained and deviated reservoirs, such as spillage, well wall instability, pressure jam and many other problems. to fix Due to the hundred years of drilling in Iran, most of the old reservoirs have either been emptied or are being emptied. Another characteristic of Iran's fields is the presence of fractured reservoirs with high permeability, which makes drilling in them very difficult and causes loss of capital and irreparable damage to hydrocarbon reservoirs. Unfortunately, despite the many advantages of these fluids, there is still no operational experience of them in the fields of Iran.کلیدواژه ها
