Abstract

The production of coalbed methane (CBM) wells in China is generally low, and the CBM geological research is seriously divorced from the engineering, so it is urgent to introduce the idea of geological engineering integration, which is helpful to form a scientific engineering decision. In this paper, the idea of constructing a CBM geological engineering integration platform is proposed, and its business framework and function framework are built. Various professional software tools are integrated, such as Petrel for geological modeling, compass for drilling and completion design, MFrac for fracturing design, and CBM-SIM for reservoir numerical simulation. An integrated shared database of geological engineering, a gas production contribution monitoring platform, and a remote control platform for intelligent drainage are established. The standard workflow for geological engineering integration technology is solidified, and the corresponding professional knowledge base is established. On the platform, professional barriers between the upstream and downstream of the CBM exploration and development are removed, and all the process data and results are shared to create a service platform of CBM development geological evaluation, engineering design optimization, and data sharing. Based on the 3D geological model of coal reservoirs, a comprehensive evaluation of geology and reservoirs is carried out. The drilling, cementing, fracturing, drainage and other engineering operation schemes are designed and dynamically optimized. The gas production contribution monitoring and intelligent drainage and production remote control system are integrated to realize the integration of CBM geological engineering and the whole life cycle management of the project. At the same time, the repetitive workload can be reduced to improve the efficiency of CBM exploration and development engineering and the production of gas wells, resulting in reduced cost and increased efficiency.
