Design And Implementation Of Simlation For Complex Perforation Software

Oil resources in the development of world economy, bears an important role, notonly people’s daily lives, but also a very important strategic resources of countriesaround the world. Oil extraction capacity of a country has a vital role on the nationaleconomy, strategic.Composite perforating new composite gunpowder perforation, by detonatingexplosive, Perforating, gas fracturing, downhole acting realtime data acquisitionsystems, and ground data processing system a combination of a completion tool, themainly used for low porosity and low permeability strata perforating, is a new type ofperforation method developed in recent years. The main principle of the composite jobperforator outer layer increased the high-energy compound gunpowder, and theformation of a high pressure pulse formation fracturing operations in the perforationtunnels shaped perforation of the perforated shells from composite powder deflagrationto formation of a certain length of cracks in the rock to improve the performance ofcompaction with the flow of the perforation tunnels; compared to the conventionalperforating technology, composite perforating can effectively improve the permeabilityof tight formations and lower near the wells with contamination, can greatly improvethe stratigraphic the effect of oil has very important significance to improve the singlewell oil and gas production and formation recoveryThis project to undertake a detailed analysis of the composite perforationsimulation software and completed the following work:1) First, a detailed study of the composite perforation process to complete theanalysis of influencing factors on completion, compound perforation principle andmethod of simulation software for composite perforation. And established amathematical model of composite perforation, including the mathematical model ofcomposite blast shock and formation fracturing mathematical model. Last listed indetail the technical parameters of the composite perforation mathematical modeldesigned.2) Composite perforation simulation software requirements modelingobject-oriented design. Carried out in accordance with the objectives and principles ofcomposite the perforating simulation software design, combined perforation simulation software needs to use case modeling. Detailed design of the: top-level use cases, usecase diagram, the detailed features, geological prospecting use cases of the basic flowchart, set the work area with cases of the basic flow chart, set the oil platforms cases ofthe basic flow chart, drilling cases the basic flow chart, drilling use cases modify anddelete flowchart use case basic flow chart, the drilling and completion flow chart ofcases, an oil modeling cases flow chart, adjust the parameters of use case basic flowchart, adjust the parameters of flow charts units of cases additional parameters,adjusting the parameters of flow charts of the cases additional parameters for theassembly of perforating guns use case flow chart, the transfer tool use case flowdiagram, computational analysis of the use case flow chart and draw a curve with casesflowchart. Complete design work on the requirements use cases.3) Composite perforating simulation software detailed design, including the wellwith patients, coordinate with the cases, PulsFrac calculation and parameter displaycases static class design, and drilling operations order, the order of casing cementingoperations, perforating operations order and the annulus Dynamic diagram of operationsequence design.4) It shows the core of the composite the perforating simulation softwareimplementation code, and discusses the characteristics of the composite the perforatingsimulation software interface of simulation software for analysis of compositeperforation. Instance of the application analysis to verify the validity of the compositeperforation simulation software.
