Abstract

The invention discloses a fracturing pump assembly process control method based on the fracturing technology. The fracturing pump assembly process control method comprises the following steps: the operation process of a fracturing pump assembly is divided into a plurality of operating phases, and the operating parameter of the fracturing pump assembly at each operating phase is set; the fracturingpump assembly sequentially carries out the tasks of each operating phase, and after finishing the former operating phase, the fracturing pump assembly automatically switches to next phase; when the fracturing pump assembly carries out the tasks, according to the operating parameter variation, the fracturing pump assembly carries out phase keeping and recovering, phase skip or operating parametermodification. A process control system carries out the process control method and can be blended in a fracturing pump control system to improve the fracturing operation reliability; the construction operational quantity is automatically adjusted according to the process demands, so that the fracturing pump assembly carries out sequential quantitative construction according to a construction operation table, the workload of an operating staff is greatly reduced, the construction operating efficiency is improved, extra loss of the labor cost and the equipment cost is also avoided, and the construction cost is greatly saved.

Description

technical field [0001] The invention relates to the field of oil exploration and fracturing operations, in particular to a process control method and system for a fracturing pump unit based on a fracturing process. Background technique [0002] Shale gas is natural gas retained in oil-generating rock formations. It is a type of "unconventional natural gas" and belongs to the same category as "coal bed methane" and "tight gas". As one of the emerging energy disciplines, the research and development of shale gas is not easy. Constrained by the theoretical and technical bottlenecks in exploration and development, currently, except for the United States, which has commercialized a large number of shale gas development and utilization, other countries are still in the research and development stage. With the development of exploration and development technology, unconventional natural gas will become an important low-carbon resource in my country in the future. [0003] Due to ...
