在对低孔隙度、低渗透—特低渗透砂岩油气藏压裂中,由于储层基质向裂缝的供油气能力较差,仅靠单一的压裂主缝很难取得预期的增产效果。因此,提出了适合低孔隙度、低渗透、低压储层的“体积压裂”技术。随着苏里格气田水平井大面积的开发,针对其水平井的新工艺新技术也层数不穷,特别是今年“体积压裂”的水平井尤为突出。 In the fracturing of low porosity, low permeability and ultra-low permeability sandstone reservoirs, it is difficult to obtain the expected stimulation effect due to poor supply of oil and gas from the reservoir matrix to the fractures. Therefore, a “volume fracturing” technique suitable for low porosity, low permeability and low pressure reservoirs is proposed. With the large-scale development of horizontal wells in the Sulige gas field, there are numerous new technologies for horizontal wells. In particular, horizontal wells with “volume fracturing” are particularly prominent this year.
