Abstract: | LWD (logging while drilling) data has been used to explore complex subtle reservoirs by real-time visual interpretation and geo-steering. The method comprises of computer communication, well log data processing, formation recognition, reservoir modeling and model updating in real time. We studied the key technologies related to real-time LWD data visual interpretation and geo-steering and developed computer software with Chinese intellectual property rights covering the following important aspects: 1) real-time computer communication of well site LWD data; 2) visualization of geological model and borehole information; 3) real-time interpretation of LWD data; 4) real-time geological model updating and geo-steering technology. We use field application examples to demonstrate the feasibility and validity of the proposed technologies. |
