Abstract
The F oil layer is a typical low permeability reservoir. Conventional development cannot develop the low permeability reservoir effectively, so the long horizontal wells cooperate with volume fracturing in the way to transform the ultra-low permeability reservoirs. Well P1 is the first long horizontal section well drilled by our company. Based on its condition and formation characteristics, it conducts a large-scale multi-segment multi-cluster volumetric fracturing field test of horizontal wells to realize the volume utilization of the layers. The test verifies the feasibility of volume fracturing in the reconstruction of horizontal wells and the applicability of the supporting process in the application of ultra-low permeability reservoirs. At the same time, the fiber sand-adding process test for tight oil type II reservoirs was conducted. After the fracturing, tracer monitoring was performed on the flowback liquid to ascertain the produced fluid of each layer, and it was determined that the crack cutting technology had a good transformation effect. The design and development of well P1 is of guiding significance for the development of horizontal wells in low permeability reservoirs in the future.
