一种求解压裂施工前置液量的方法

A Method of Evaluating the Quantity of Ahead Fluid in one Hydraulic Fracture Treatment.

前置液量为压裂施工中的关键数据 ,其用量的多少 ,对于压裂施工的成败和油气井经济效益的高低有着重大的影响。前置液量的设计 ,主要依据储层的地质条件即孔隙度、渗透率、饱和度等物性参数和施工的规模而定。本文在理论计算的基础上 ,根据储层特征模拟设定的裂缝形状和施工参数 ,用时间等分法求解了某次压裂施工的前置液量。经现场应用 。

The quantity of ahead fluid is a key datum in hydraulic fracture treatments. It has an important influence to the effect of a hydraulic fracture treatment and the economic benefit of oil and gas wells. The design of the quantity of ahead fluid is based on reservoir geologic conditions mainly including porosity, permeability and saturation etc., and the scale of the treatment. Based on theoretic calculation, fracture shape and treatment parameters are given in terms of formation characteristics, and the quantity of ahead fluid for one treatment has been evaluated by using the time halving method. By field application, the method receives good effects.
