东胜气田什股壕区块储层低孔、低渗、气水关系复杂,压裂改造是气田高效开发的有效手段。在水力裂缝高度影响因素分析的基础上,认为施工排量是影响裂缝高度延伸的关键可控因素。并以断裂力学理论探讨垂直裂缝的二维延伸过程,模拟计算施工排量与裂缝高度的影响关系曲线,优化出什股壕区块水平井压裂施工的最优排量。成功应用于什股壕水平井的压裂施工,取得了较好的效果。最后结合井温测井等手段,综合验证排量可以有效控制人工裂缝的高度延伸。

Shenguhao block has the characteristics of low porosity, low permeability and complex gas-water relationship in Dongsh-eng gas field. Fracturing transformation is an efficient measure to efficient develop gas field. Based on influential factors analysis of hydraulic fracture height, we considered that construction displacement was the key controllable factor to influence fracture height extension. By discussing two-dimensional extension process of vertical fracture based on fracture mechanics theory, and analog cal-culating relation curves of construction displacement and fracture height, the displacement of horizontal well fracturing in Shengu-hao block was optimized.Accordingly, this research was successfully applied in this block and achieved preferable effects. Finally, combined with temperature logging means, this paper proved that displacement could effective control height extension of artificial fractures.
