Abstract
- Near-bit drilling gamma ray imaging system has become an important technical equipment, oil and gas development of conventional MWD (measure while drilling) installation position bit far distance, There is a significant delay in the acquisition of data while drilling, and the inability to determine the upper and lower interfaces and dip angles of the traversing formation in a timely manner, which affects well trajectory control and reduces the timeliness of decisions and adjustments while drilling. These problems have always been the focus of oil drilling research. The gamma imaging system near bit was discussed, and the effects of various factors on the gamma response speed were analyzed. Due to the proximity of the formation measurement unit to the bit, the near-bit gamma imaging system has a high transmission speed and a fast response in order to obtain near-bit gamma. Through the development of prototype and field experiments, the results show that the system can timely and accurately understand the formation, achieve a high consistency between drilling trajectory and geological trajectory, well trajectory is better, which provides a possibility for the development and utilization of complex oil and gas wells.
