低渗透油藏压裂施工参数对压裂效果的影响分析

长庆油田总体上具有低孔、低渗、低压的储层特点，利用水力压裂方法改造低渗透油藏，在提高储层产能、增产增效方面见到了显著效果，但在许多井次的水力压裂措施中，仍存在许多无效或低效措施，造成一定的资金浪费。本文针对长庆油田胡153区块长4＋5储层物性特点及井网特征的分析，优化裂缝形态。通过现场施工参数与产量关系的统计，结合优化的裂缝形态，运用FracProPT三维压裂软件对数据进行模拟，优化出最优的施工参数，对压裂措施方案起到一定的借鉴作用，从而提高压裂的措施效果。进一步提高压裂成功率。

Effect of Fracturing Parameters on the Fracturing Result of Low-permeability Reservoirs

Changqing oilfield is a low porosity, low permeability and low pressure reservoir. The hydraulic fracturing method has remarkable effect for improving the capacity of low permeability reservoirs, but in many times of hydraulic fracturing measures, there are still many invalid or ineffective measures, which can cause a certain amount of money waste. In this al;ticle, based on analysis of geological features and well pattern of Chang 4＋5 in Hu 153 area of Changqing oilfield, fracture morphology was optimized. Through statistics of field fracturing parameters and production, combined with optimized fracture morphology, the data were simulated by using three-dimensional fracturing software FracProPT. Then the fracturing parameters were optimized, which can provide a reference for planning fracturing scheme to improve fracturing effect.
