A simple adding device for fracturing fluid additives in oil and gas fields

Abstract

The invention discloses a simple adding device for fracturing fluid additives in oil and gas fields. The addition of fracturing fluid additives during operation provides an efficient and convenient device. The invention controls the dosing metering pump through the control module, and adjusts the addition process of different fracturing fluid additives according to the actual situation and different fracturing stages, so as to achieve the purpose of timely adjustment and precise addition. At the same time, the addition process of fracturing fluid additives can be remotely monitored and controlled through the remote control interface, and linkage control can be realized with the entire fracturing process, which greatly reduces the time cost and labor cost of the entire fracturing operation. The invention is used in the process of adding fracturing fluid additives for fracturing operations in oil and gas fields, and has the advantages of simple operation, precise control, high efficiency and low cost.

Description

technical field [0001] The invention belongs to the field of petroleum engineering, and in particular relates to a simple adding device for fracturing fluid additives in oil and gas fields. Background technique [0002] In recent years, with the continuous change of the energy pattern, the development of unconventional oil and gas resources has attracted much attention, especially the clean and environmentally friendly shale gas resources have been paid more and more attention. However, the structural characteristics of shale reservoirs, such as low permeability and low porosity, make their exploration and production difficult. Most shale gas fields must undergo reservoir reconstruction to obtain higher recovery ratios. At present, the most effective means of developing shale gas in the world is hydraulic fracturing, that is, to transform the reservoir structure through pressure and slick water fracturing fluid. Among them, drag-reducing water fracturing fluid is a new type...

AI Technical Summary

Problems solved by technology

In general, oil and gas fields need hundreds of cubic meters of fracturing fluid in one fracturing process. The water used to prepare fracturing fluid is usually stored in multiple water tanks. The preparation process is limited by the field conditions of oil and gas wells. It is difficult to ensure that the concentration of the same fracturing fluid additive in different water tanks is the same when each water tank is individually mixed, which may affect the effect of subsequent fracturing operations

At the same time, because oil and gas wells are generally located in relatively remote places, the traffic is very inconvenient, and the existing liquid distribution equipment is inconvenient to transport, which brings unpredictable risks to fracturing operations

And the concentration of the fracturing fluid is fixed after pre-mixing, and the concentration of the fracturing fluid cannot be changed at any time during the fracturing process according to actual needs

Separating fluid dosing from fracturing will result in increased overall operating time and increased interaction between different tasks
