Abstract

With the gradual development of economy, the demand for petroleum resources is also increasing, and the exploration of petroleum gradually develops into ultra-deep wells. The deeper the area is, the harder the formation rock is, and the worse the abrasiveness and drillability is. When drilling in hard formations, it is obvious that the drill fails quickly, the speed of mechanical drilling is difficult, and the cost is high. The composite drill can not only suppress or even eliminate stick-slip that occurs during drilling, but also reduce the situation of skipping, which has higher value in rock formations. The author briefly introduces PDC impact composite drill, and analyzes the rock breaking mechanism of PDC impact composite drill.
