Initiation Pressure

Horizontal well hydraulic fracture construction technology has already become the main development means of low permeability reservoir, and the crack initiation pressure is a key factor in fracture construction. Taking ABAQUS as the platform, combined with rock mechanics, elastic mechanics, fracture mechanics, damage mechanics and fluid-solid coupling theory, to establish horizontal well mechanical model, crack initiation law of horizontal well under different conditions were obtained by using finite element method. According to the horizontal well fracture tested data in Daqing peripheral oil fields, the crack initiation pressure and numerical simulation results are in good agreement, it shows that the numerical simulation method is reasonable, then analyze influence factor of crack initiation pressure on the basis.

Due to the influence of the environment of measurement and complex pore structure in low-permeability reservoir, we use single-well logging data alone to discriminate the degree of reservoir flooded has multiple solutions. In the water flooding procedures, water well and oil well have formed a dynamic developing unit. And with the water propelling, some sand bodies were flooded by water before the well was drilled. The dynamic information of developed wells in connected sand bodies (such as moisture rate and minimum layer water absorption profile, etc.), can reflect the level of water-flooded in some degree. This paper construct the rules of distinguishing the water flooded layer by dynamic analysis data on the basic of dynamic developing unit, which has prolonged the identification accuracy of water flooded layer degree of low-permeability reservoir efficiently.

Oilfield Development

In order to improve the production degree of reserves in low permeability oilfield, taking Chang 2 reservoir in Bailangcheng oil region as an example, the movable fluid saturation and its influencing factors were studied by using NMR and high speed centrifugal method, on this basis, the application of movable fluid saturation in low permeability oilfield development is studied. The results show that the pore radius of low permeability reservoir is large, the micro-fine throat is developed, the movable fluid mainly exists in the volume controlled by the throat, the saturation of the movable fluid is low, and the production is difficult. Based on the relationship between the movable fluid saturation and permeability, single well geological reserves and permeability, availability of reserves and remaining movable reserves are evaluated, and the key areas of oilfield development adjustment are determined. According to the movable fluid saturation, the reservoirs are classified to predict the theoretical development effect of the reservoir, and the actual development effect of the oilfield is evaluated by the ratio of the recoverable reserves and movable reserves predicted by the dynamic method, the adjustment space of oil field is analysed. The results of this paper have important reference value for the development policy and adjustment policy of low permeability reservoir.
