Research On Criteria Determination And Data Base Building For Formation Selection Of Turnaround Fracturing In Chaoyanggou Oil Field

With the development of Chaoyanggou Oil Field and the increasing of well number withturnaround Fracturing, it s much more difficult to select wells and layers，and the effect offracturing stimulation became worse. At present, people mainly select fracturing layers byexperience and simple analysis on dynamic and static data, which is sightless and uncertain,such situation influence the effect of fracturing and measurement efficiency. To increasecontribution rate of fracturing, improve the evaluation after fracturing, determinate thefracturing layers reasonably, detail the criteria for wells and layers selection, and enhance theeffect of fracturing, we study wells and layers selection for fracturing in ChaoyanggouOilfield in depth by grey correlation and univariate analysis, which deepen the understandingon geological characteristic of fracturing block, and realize the goal to enhance the degree ofdetailing fracturing treatment; enhance the pertinence of plan design by fracturing treatmentoptimization, thus to realize optimization on fracturing operation, which is instructive toenhance the development degree of remaining reserves and the effect of fracturing treatment.Based on the collection and calculation of parameters for fracturing wells, the articleanalyzed the main factors affected fracturing result, valuated the main factors which affectstimulation result by grew correlation and Analytic Hierarchy Process (AHP), calculate theeconomic limit of fracture measures by break-even point analysis, and build databasesoftware for wells and layers selection of fracturing...
