【摘要】：限流壓裂技術(shù)是針對(duì)低滲透、薄互多層改造的主要措施之一,限流壓裂成功與否的關(guān)鍵是射孔參數(shù)的選擇和優(yōu)化。然而地層破裂壓力和孔眼摩阻直接影響射孔參數(shù)的選擇,在射孔參數(shù)選擇中孔密是最容易控制的影響參數(shù),因此在限流壓裂射孔參數(shù)設(shè)計(jì)中往往對(duì)孔密進(jìn)行優(yōu)化選擇。 本文主要介紹了限流壓裂工藝原理、工藝背景、適用對(duì)象、施工程序及限流壓裂現(xiàn)場(chǎng)應(yīng)用效果分析,從而了解了限流壓裂的各個(gè)過(guò)程和設(shè)計(jì)方法。目前主要有三種布孔設(shè)計(jì)方法,其共同點(diǎn)是根據(jù)各小層厚度和改造規(guī)模來(lái)平均分配射孔數(shù),根據(jù)平衡壓力方程計(jì)算出孔眼摩阻值,再由孔眼摩阻計(jì)算出總射孔數(shù)。 為了更加精確的選擇射孔參數(shù),本文主要對(duì)地層破裂壓力和壓裂過(guò)程中摩阻變化進(jìn)行了研究；地層破裂壓力預(yù)測(cè)模型較多,如伊頓公式、安德森公式、黃榮樽模型等,其中大部分預(yù)測(cè)模型具有一定的針對(duì)性,本文闡述了每種預(yù)測(cè)模型適用條件及參數(shù)的獲取。摩阻類型包括：孔眼摩阻、裂縫彎曲摩阻及沿程摩阻；其中孔眼摩阻是影響布孔設(shè)計(jì)的關(guān)鍵參數(shù),文中重點(diǎn)介紹了射孔參數(shù)對(duì)孔眼摩阻的影響規(guī)律。 最后,以長(zhǎng)8儲(chǔ)層某口井為例,利用四種地層破裂壓力預(yù)測(cè)模型建立不同的破裂壓力剖面,為了更好的反映目的層破裂壓力剖面,因而選取平均破裂壓力建立目的層的破裂壓力剖面,綜合現(xiàn)有的布孔設(shè)計(jì)方法重新調(diào)整了布孔方案,并且給出了平均破裂壓力剖面與射孔數(shù)的對(duì)應(yīng)關(guān)系。現(xiàn)場(chǎng)施工曲線表明,該方法相繼壓開(kāi)三個(gè)目的層,并且增產(chǎn)效果顯著。
[Abstract]:Flow limiting fracturing technology is one of the main measures for low permeability and thin interlayer reconstruction. The key to the success of flow limiting fracturing is the selection and optimization of perforation parameters. However, formation fracture pressure and hole friction directly affect the choice of perforation parameters. Pore density is the most easily controlled parameter in the selection of perforation parameters, so the optimum selection of perforation parameters is often carried out in the design of perforation parameters for flow limiting fracturing. This paper mainly introduces the principle of flow limiting fracturing technology, technology background, applicable object, operation procedure and application effect analysis of fluid limiting fracturing field. At present, there are three kinds of hole layout design methods. The common point is that the perforation number is equally distributed according to the thickness of each layer and the reconstruction scale, and the hole friction value is calculated according to the equilibrium pressure equation. Then the total perforation number is calculated from the hole friction. In order to select perforation parameters more accurately, this paper mainly studies formation fracture pressure and friction change during fracturing, and there are many prediction models of formation fracture pressure, such as Eaton formula, Anderson formula, Huang Rongru model, etc. Most of the prediction models have some pertinence. This paper describes the applicable conditions and parameters of each prediction model. The friction types include: hole friction, crack bending friction and along the path friction; The hole friction is the key parameter which affects the design of the hole. The influence of perforation parameters on the hole friction is introduced in this paper. Finally, taking a well in Chang 8 reservoir as an example, four kinds of fracture pressure prediction models are used to establish different fracture pressure profiles in order to better reflect the fracture pressure profile of the target layer. Therefore, the fracture pressure profile of the target layer is established by selecting the average fracture pressure, and the hole layout scheme is readjusted based on the existing hole layout design methods, and the corresponding relationship between the average fracture pressure profile and the perforation number is given. The field construction curve shows that, The method uncovers three target layers one after another, and the effect of increasing yield is remarkable.
