可指导压裂设计

有一定的推广意义。

Abstract

Before the design of the horizontal wells

fracture

we took the well LP-133HF in the half deep to deep layer of the overpressure shale gas reservoir in southeast Sichuan basin as the research object. And by the software--CMG

we established the numerical model of the single well to simulate the sensibility of the fracture parameters of the horizontal wells and analyze the potential production promoting factors. The results showed that four factors

that is

the fracture conductivity

fracture half length

fracturing length and well spacing

affected most on the development of the shale gas wells

while the single fracturing length had the minimal effect and negative correlation. Finally

we obtained a set of fracturing parameters suitable for well LP-133HF

which is proved to be credible in field application. This analysi

s method is reliable and applicable for the guidance of the fracturing design. It has certain promotion significance.
