Practice and Understanding of Horizontal Well Drilling and Production Integration in Overseas Petroleum Projects

In the face of complex oilfield geological conditions and external operating environment, overseas oil projects continue to promote technological innovation, application and management. According to the main contradictions faced by horizontal well development, Using modern management methods and means, in view of the obvious decline of single well production, the high development cost of horizontal wells, and the problems in process technology, etc. Based on the scientific theory of systems engineering, In accordance with the principle of “cost reduction and efficiency increase, multi-party collaborative operation”, By analyzing domestic and foreign horizontal well drilling and completion technology and integrated application experience, optimizing and adjusting the contract mode, insisting on technological innovation, insisting on technological application and management improvement, Strive to achieve the integration of mechanism, technical resources and organizational management, etc. The first field application was carried out in the North Troyes Oilfield in the Pre-Caspian Basin, Kazakhstan, and achieved good results, laying the foundation for the efficient development of low-permeability heterogeneous carbonate oilfields. It has certain promotion and application value in Central Asia.
