“…As we know, the formation is different in terms of stress distribution and fracturing methods., the length of hydraulic fractures after fracturing will vary [9][10][11][12]. Of course, the length of hydraulic fracture also plays an vital role in the oil field well production.…”

The fractures produced by hydraulic fracturing will close to a certain extent under the action of formation stress, which will significantly affect the testing and productivity prediction of tight reservoirs. It is necessary to build an accurate model considering the fracture closure to predict the production characteristic of tight reservoirs. In this study, we propose a method to predict the productivity of staged fractured horizontal wells considering fracture closure. To address the research objectives, In most cases, there are many methods to solve the model, such as Stehfest numerical calculation, Pederosa algorithm, etc., which can realize the analysis and application of the model from different angles. These methods facilitate the analysis of the closing pressure's impact on fracture conductivity and the evaluation of fracture parameters' influence on well productivity. The results show that in the actual production process, the value of hydraulic fracturing parameters is not very high, but has a reasonable value range. Among the measures to increase the production of tight reservoirs, the most important ones are the preparation of fracturing method and fracturing design. One of the most important indicators to affect the fracturing effect is the fracture pressure in the fracturing system and the fitting curve of closed fracturing. If the fracture closure pressure increases, the fracture conductivity decreases more obviously.The key parameters of artificial fractures, especially the conductivity, will be a critical point. Of course, it is necessary to fully improve reservoir productivity and optimize various parameters of fractures.

“…For the special low permeability reservoir, the method of horizontal drilling and stage fracturing must be used to produce oil. Due to reservoir lithology, if hydraulic fracturing is carried out in a fractured low permeability reservoir, natural fractures of the reservoir will be opened and connected to each other when the main fractures are formed, and a complex fracture network structure and SRV area R will be generated around them (as shown in Figure 1) [2]. In order to simplify the original fractured reservoir and its internal fracture network structure, the Warren-Root dual medium model is proposed.…”

Daqing Oilfield is rich in low permeability reservoirs. In order to fully understand the development dynamics of ultra-low permeability reservoirs, this paper takes Daqing Oilfield as an example and studies the productivity dynamics of fractured horizontal Wells by numerical simulation method. The results show that the productivity of fractured horizontal Wells decreases exponentially with the decrease of formation permeability. The productivity of fractured horizontal well increases with fracture length and decreases with fracture spacing. With the increase of formation coefficient and reservoir thickness, the productivity increase of fractured horizontal Wells decreases. In the case of small well spacing, the smaller the formation coefficient and reservoir thickness, the higher the productivity of fractured horizontal Wells. Compared with conventional vertical Wells, fractured horizontal Wells have better production performance.
