基于地质-工程一体化的纠偏轨道优化设计及产能评价
Optimization design of deviation-correction trajectory and production evaluation based on geology-engineering integration
摘要
Abstract
In the drilling process of shale gas reservoirs,if a horizontal well deviates from its planned trajectory,the inter-well interference effect can be intensified during later fracturing and production stage.In order to reduce the production loss,it is expected that the drilling deviation can be adjusted to the planned track efficiently and safely.In this study,a multi-ob-jective optimization design model of deviation-correction trajectory was established considering production loss evaluation.Firstly,the relationship between fracturing influence region and fracturing depth was figured out,and a calculation formula of multi-fracture production was obtained in terms of a volumetric flow concept.Based on the proposed"double arc"trajectory design model,the calculation method of the production loss after trajectory correction was obtained.Finally,a multi-objective optimization model based on geology-engineering integration was established in consideration of the evaluation of potential en-ergy.The results show that optimizing fracturing depth and reducing fracture length can weaken the inter-well interference effect and reduce production loss.The minimum curvature value can result in a trajectory with the greatest production loss and the least potential energy.The combination of the geological-engineering evaluation objectives can ensure lower drilling risk and higher shale gas production.The overall drilling and fracturing parameters can be optimized,in which the potential energy of the deviation-correction trajectory can be reduced by 23.9%.关键词
