The study research the productivity formula in low permeability reservoir with vertical wells combined with fracturing well of the five point rectangular pattern, seven spot pattern, nine spot pattern, as well as the productivity of anti-nine rhombus fractured vertical well mixed pattern, and to which of the five-point rectangular pattern and the law rectangular fracturing well pattern optimization analysis. The analysis revealed widening well spacing, narrow row spacing, so that the shape factor well network within a certain range, can improve the development effectiveness, and when length of the crack and area of well spacing were given, can determine the length and width of rectangular pattern.

Enhance Oil Recovery

The pilot block is a heterogeneous reservoir with low permeability which is only 100-200(mD). Polymer flooding will be used to enhance oil recovery (EOR). Therefore, some experiment will be carried out in this pilot block .According to the simulation results, we can infer the effect factors of the polymer flooding such as concentration, injection rate, slug amounts, and well pattern. It gives us effective information for the field development plan.

Aimed at ultra-low permeability reservoir, the large natural outcrop model has been made for researching the oil reservoirs porous flow law deeply, and the inverted nine-spot equilateral well pattern also has been designed which is the commonest well patter during the oilfield exploitation. The flow fields have been measured during the experiment in different displacing period (0.3PV, 0.6PV and 1PV). The research shows that fluid flow has obvious directivity, and it strongly affected by heterogeneity of the reservoir. In addition, the regions between the edge production wells are much more difficult to be exploited.

Low Permeability Reservoirs

Low permeability reservoirs have abundant reserves, accounting for about one-third of all the reservoir storage, but the development is difficult and the recovery is low because of its poor natural property. Reasonable well pattern, well pattern parameters and fracture parameters can be effective in improving the development of low-permeability reservoir. Therefore, studying flow law of various well networks, choosing a reasonable well pattern and corresponding well parameters, are key issues of cost-effective development of low permeability reservoir. Based on extensive investigations of former researches, this paper studies the flow law of vertical well patterns and the effect of permeability differential on flow law. Adaptive study of those different kinds of well patterns has been done by numerical simulation method, including the five point well pattern, inverted seven point well pattern and the inverted nine point well pattern. Studying the typical horizontal well pattern on the flow law, comparing the characteristics of the streamlines. Choosing a reasonable form of well pattern and the well pattern parameters.
