压裂参数对水平页岩气井经济效果的影响
Economic Influence of Hydraulic Fracturing Parameters on Horizontal Wells in Shale Gas Bed
摘要
Abstract
Economic effect of shale gas wells is evaluated under different fracturing parameters and the influence of fracturing well space, fracturing stages and proppant volume on fracturing effect is studied by adopting productivity simulation which regards NPV and IROR as evaluation indicators. The results of the study shows that the influence of fracturing well space, fracturing stages and proppant volume on fracturing effect is obvious; it' s not right that the longer the fracturing well space, the better the fracturing effect, however, when fracturing stages and sand volume are small, dense fracturing with short horizontal section length can even get a better effect; fracturing stages can influence productivity and economic effect by changing the controlled volume of individual stage fracturing and proppant density; sand volume changes flow channel environment by proppant, influences productivity, has an optimal density and combined with the 2 factors above influences economic effect. The preparation of drilling and completion program should consider the 3 factors mentioned above and optimal FDP should be prepared.关键词
