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。
Changqing Oilfield generally has reservoir characteristics of low porosity, low permeability and low pressure. Using hydraulic fracturing method to transform low permeability reservoirs has notable effects in improving reservoir productivity and increasing productivity and efficiency. However, in many wells In hydraulic fracturing measures, there are still many ineffective or inefficient measures, resulting in some waste of funds. In this paper, the Changqing Oil Field Hu 153 block length 4 +5 reservoir physical characteristics and well pattern analysis, optimization of fracture morphology. According to the statistics of the relationship between the construction parameters and the output of the site and the optimized fracture morphology, the data were simulated by FracProPT 3D Fracturing Software to optimize the construction parameters and play a certain reference role in the fracturing scheme, Crack effect of the measures to further improve the success rate of fracturing.
