Feasibility Study and Some Knowledge of Volumetric Fracturing of Gas Wells in Tight Reservoir

针对目标区块地质特征,结合体积压裂缝网形成机理与缝网形态,进行致密储层体积压裂可行性评价。优选压裂工程甜点区,形成一套致密气储层水平井体积压裂技术及配套工艺,提高了压裂改造的人工裂缝导流能力,为致密砂岩气的开发提供了新的压裂改造思路和可行的施工模式,以提高致密气藏增储上产的技术水平。

According to the geological characteristics of the target block, combined with the formation mechanism and structure of volume fracturing fracture network, the feasibility of volume fracturing of tight reservoir is evaluated. The dessert areas of fracturing engineering are optimized to form a set of volume fracturing technology and supporting process for horizontal wells in tight gas reservoirs,which improves the conductivity of artificial fractures for fracturing transformation, provides new fracturing transformation ideas and feasible construction modes for the development of tight sandstone gas, and improves the technical level of increasing reserves and production in tight gas reservoirs.
